Should You Tint Your Classic's Windows?

We’re based in the sunshine state, so our average climate doesn’t exactly help classic cars’ air conditions. Apart from performing routine maintenance on your classic’s AC, one preventative measure to keep it performing its best is tinting its windows.

You have control over the tint’s shade and UV blockage. Not only that, but your options are almost limitless. You can save money and apply the tint yourself, or you can find a local shop to do it for you.

One issue people find with tinting a classic’s windows is that it’s essentially a modification. Some feel that any changes such as altering the factory glass take some of the originality out of the car. However, if done correctly, tinting is temporary and can be removed at any time.

If you’re still not on board, consider this: your classic’s AC is precious, especially if it’s original. Therefore, it needs any help it can get to stay functional. The biggest advantage with window tints is that the film can block anywhere from 35-65 % of heat from building up in the car. You can decrease both fuel consumption and AC wear, ultimately putting a lot less stress on it. Plus, installing window tints protects your investment, blocks up to 99% unhealthy UV rays that harm your skin and upholstery, and hinders windshield glare from sunlight and headlights. Classic car guru and enthusiast Andrew Golseth gives his views on tinting classic windows here.

We personally recommend ceramic window tint. It’s completely metal-free so in addition to 99% UV protection, glare control, and heat rejection, it won’t interfere with any of your electronics. Its nano-ceramic technology is also customizable; you have a range of different charcoal shades to choose from that pairs best with your classic.

Applying a tint specifically to the windshield is legal in most states, but we recommend you check out your local laws to be on the safe side.

 

3 Reasons to Upgrade to Parallel Flow A/C Condenser

Seeking better performance from your AC system? Consider changing from your traditional tube and fin condenser to a parallel flow condenser. Modern condensers are more efficient due to materials used and increased surface area.

ac condensor


A little history on the automotive air conditioner condenser. Copper was the preferred metal used with R12 to allow for efficient heat exchange as refrigerant flowed through the system. Condensers were designed as one continuous tube wrapping back and forth across a plane to allow for heat to radiate away from the system. Although more expensive, eventually aluminum began replacing copper as a more effective way to provide the necessary cooling. From the tubes being made of aluminum, to also the fins manufactured from aluminum, ac systems continue to evolve.


Today, manufacturers utilize parallel flow condensers with R134a. Using multiple tubes rather than just a traditional single tube, parallel flow condensers maximize contact with the refrigerant to increase the transfer of heat away from the system. This allows the automotive air conditioning system to run even more efficiently than the tube and fin setup.

In summary, here is why you should consider investing in a parallel flow condenser as an upgrade to your tube and fin setup:

  • There is more metal surface area available for the refrigerant to pass over leading to more efficient heat exchange.
  • Our Parallel flow condensers are built to be direct bolt-in replacements of the OE unit – no modification needed on your car.
  • Refrigerant utilized can be either R12 or R134a, and is ideal if you are considering upgrading to R134a.

Here at Original Air, we manufacture our own line of parallel condensers that are direct/exact fit for your original factory AC system.

 

VIR Eliminators and Extra Parts

Original Air’s VIR Eliminator kits are designed to replace all VIRs that GM manufactured. While the orientation of the evaporator tubing varies from car to car, the VIR Assemblies are all the same.

The tubing needs to be manipulated even when removing and reinstalling the stock VIR. The same is true when using our Eliminator kits.

Our customer who has a classic Chevrolet Nova needed the orifice block and associated lower evaporator tube to be moved toward the evaporator case so that there was clearance for the accumulator to sit vertically (critical to allow oil flow back to the compressor). He was hesitant to do so until we explained about removing/reinstalling the original VIR.

The tubing will move where you want it to, but remember to be gentle.

Not too long ago, we had a customer requesting an extra part for the upper fitting of the accumulator since his upper evaporator tube didn’t seem long enough.

Note that if your fitting is too short, it means one of two things:

  • Someone has modified it
  • The wrong evaporator is in the vehicle

All original VIR Equipped vehicles can utilize the Eliminator kit, as long as the rest of the system (evaporator, liquid hose, compressor suction hose) are in factory stock form.

Where to Buy Muscle Cars Online

When shopping anywhere on the Internet, there are two rules. First, make sure the site you are purchasing from is secured. Second, if it feels like a scam, it most likely is. If it’s too good to be true, don’t trust it. With those rules in mind, the Internet has a wealth of knowledge and resources for finding every kind of muscle car you can imagine. There are three primary ways to safely purchase a muscle car the web, each with their own positives and negatives. Prioritize your needs for purchasing methods and what makes you feel most confident in purchasing from the Internet.

Online Car Auctions

There are lots and lots of car auction sites out there. Some big, some small, with varying degree of price, quality, and location. Some of the most well-known and well -respected auction houses are Mecum, Barrett-Jackson, and ClassicCars.com. Each of these sites list some of the most sought after cars in the world and they are some of the most trusted auction houses in the business.

We prefer to use eBay Motors. It offers a certain level of security and buying options. eBay can be a slippery slope and people have been known to fall for scammers, but we refer you back to rule number 2: if it feels like a scam, it most likely is. When spending any large amount of money, be sure to contact the seller and develop a rapport with them as best you can before you purchase anything and do your best to see the car before purchasing. If you haven’t purchased from eBay before, here is a useful resource with some simple steps on how to go about doing so.

Online Classifieds

The classifieds are a dodgy group of websites, so the rules apply here heavily. Do not mistake them for dealers. These are websites that advertise independent sellers. There are many out there that have not been updated for years, so I would stick with the first page of Google when searching for these sites. Here is a little list of some of the best classifieds out there (in no particular order). Again, be always wary of scams, no matter the site.

  • Craigslist – We know, we know, this might be an obvious choice, but it is one of the best resources from gauging local prices in the area, and it deserves a mention. Craigslist offers anything and everything so be prepared to spend some time searching here to find what you are looking for. Again, be careful of scams.
  • Forums – Find yourself a model specific forum (http://www.chevelles.com/forums/) and delve into the classifieds section (http://www.chevelles.com/classifieds/) if the forum has one. Forums are great for information on any muscle car you can think of, so use them wisely.
  • Autotempest One of the most top rated sites that encompasses almost every major listing site out there.  It sorts by distance according to zip, make and model. It is honestly one of, if not the best way to search classifieds. http://www.autotempest.com/
  • Carsonline.com - One of the most muscle car -specific sites available.  While this site is straight out of the 90s, it provides you information to outside listings that you may not be able to find your own search.

Online Muscle Car Dealers

These dealers tend to be higher priced but carry a lot of rare and beautiful cars, so they’re at least a useful source to look at some great cars. Like a lot of auction sites, they can be small and regionally located. We always recommend going with the larger sites if you’re going to buy just for safety’s sake, but as with any online purchase, always assume a certain amount of risk.

If you do shop online dealers, do your best to see the car before you buy. This is an investment, not an Amazon purchase. Listed below are some of our favorite dealers.

 The Internet has completely changed the way we purchase everything, so always be careful. Finding the best deal online takes time and energy, so be meticulous and most importantly, have fun. We wouldn’t be doing this if it wasn’t fun.

Is R134a Right for my Muscle Car?

If the air conditioning system in your car is not running properly for one reason or another, you are probably looking into fixing it or getting it replaced. However, if your vehicle was made before 1995, like many muscle cars, it most likely contains R12 coolant and you might consider converting to R134a. The debate between R12 and R134a is a complicated one, so we've answered five main questions you might have when approaching this problem. 

  1. First off, what’s the difference between R12 and R134a? R12 and R134a are refrigerants used in car air conditioning systems. R12 was the first to be used and R134a is, for the most part, used today since R12 was banned. The main difference between the two is that R12 is compatible with mineral oil whereas R134a is compatible with synthetic oil. 

  1. Why was the manufacturing of R12 banned? R12 contains CFCs, like hairspray once did, that are potentially damaging to the ozone layer. It was banned because of this potential environmental risk and replaced by R134a because R134a, using synthetic oil over mineral oil, does not have the negative environmental impact that R12 does. 

  1. Why should I make the switch from R12 to R134a? The manufacturing ban on R12 makes it difficult to find at most auto stores now. If you can find R12, it has been shipped from overseas and is probably pretty pricey. It has largely been replaced by R134a, which is a cheaper and more convenient option, as well as the one that is better for the environment. 

  1. How do I convert an R12 air conditioning system to an R134a system? There are conversion kits that can help as well as conversion calculators online to aid in the conversion, but the process easy to follow with simple instructions here.

  1. I've found R12 is more effective in my car than R134a. Should I still convert to R134a, or should I keep R12? If you truly are adamant about R12, there are plenty of R12 substitutes that are better for the environment than R12. They are also more readily available than R12, which would be the hassle of using R12 since it is very difficult to find. 

All in all, R134a is preferable to R12 because it is readily available and self-manageable on top of being better for the environment. Hopefully these answers will help you understand the differences between R12 and R134a and guide you in fixing your car air conditioning system. 

Time Lapse Video of Evaporator Restoration

From our friends at Graveyard Carz, here is a time lapse video showing the disassembly and re-assembly of a rare 1971 Dodge Challenger R/T Evaporator Housing.

High Blower Speed

In September, we discussed why you should keep your original factory A/C system. But what if it’s not working?

One common issue is that a fan doesn’t reach full capacity, yet all other speeds work. Most people assume the fan switch is bad, but in reality, the cause is usually a bad blower relay. The switch doesn’t control the high speed, it controls the relay which then activates high speed.

While fan switches can eventually fail, typically they never do on their own. If a fan switch does burn out (due to a loose terminal, there are burn marks on its back, or loses any speed other than high) it’s typically the result of a deteriorating blower motor which is drawing high amperage (or a bad ground connection to the motor).

The same is the case with resistors and relays. If a resistor has a coil burn out or any terminals loose, it’s likely the blower motor. Replacing any of those components without changing or repairing the blower motor may fix the issue temporarily. However, this will only cause the newly installed parts to fail again.

So before you order any new parts for a fan that does not reach high speed, remember to check the blower motor and connections first.

Fall Inspection Checklist

 

October is Fall Car Care Month 


Get your vehicle ready for cooler temperatures this October.
 Preventative maintenance leads to fewer unexpected repairs.

 

Inspection Check List:

Heating, ventilating and air conditioning- Proper heating performance is just as important as proper cooling performance – keep in mind that we are the A/C and heating industry leader and have the largest inventory of used original parts in the business!

Exhaust system- Be aware of leaks and damage to assure harmful fumes do not enter the vehicle.

Hoses and Belts- Check for cracks, bubbles and bulges in your hoses. Don’t risk being stranded on a highway with a broken down car. Read more about replacing hoses here: https://www.originalair.com/when-should-i-replace-my-hoses

Brake System- Have brake system inspected now, especially if you will be driving in more intense weather this winter.

FluidsCheck your engine oil, coolant, power steering fluid, brake fluid and windshield washer fluid.

Lighting Check exterior lights frequently. Look for cracks, burnt out bulbs and dimmed lights.

BatteryLook for corrosion, leaking and swelling in your battery. The connection should be tight and free of corrosion.

TiresInspect tread on all four tires as well as tire pressure. Ensure your wheels are aligned and check for any bulging, cracks or bald areas.

WipersEnsure your wipers are not worn down. This will be important should you drive through any inclement weather.

 

 

Why Keep Your Original Factory A/C System?

We know you have thought about it when planning to restore or modify your classic car or truck - "Should I keep this factory A/C system?"  We get emails and calls all the time as owners seek validation for keeping their classic system and the costs to maintain.  Well, if you ever wondered, here are a couple things to keep in mind:

  • It’s cool.  Literally!  Since many classic cars and truck did not come with factory air-conditioning, and even those that did were often stripped of key parts at some point in its life, having a classic with factory air-conditioning helps it to stand out from the crowd.  Especially if it’s functioning and kicking cool air.
  • Resale value.  Having the original functioning factory air-conditioning has proven to help increase resale value.  It can also help your car sell ahead of one without factory air conditioning.
  • There are still options for getting it fixed, and in some cases, more efficient.  Original Air offers customer rebuilding & fabrication services for many parts for your classic.  We also manufacture model specific (and sometimes custom) parallel-flow condensers, sell model specific Stage-1, 2 & 3 A/C performance upgrade kits designed to improve the factory air-conditioning.
  • No need to modify your car.  Many aftermarket air-conditioning systems require some sort of modification to the vehicle and may not fit as well as the factory engineered system 

So, don't think about it!  If you have a factory A/C car or truck, keep it and enjoy the benefits of being cool.
