Preferred brand of new R4 compressor

mckpaul on Wed October 10, 2007 9:26 PM User is offlineView users profile

Year: 1984
Make: Chevy
Model: C-10 Pickup
Engine Size: 305
Refrigerant Type: R134a

The preferred supplier seems to be, just wondering, who makes the new R4 compressors they sell? And was wondering what are other preferred brands (if any) of new R4 compressors are out there that you guys that do this all the time like to use.

We have multiple sources depending on price and availability at the time. I don't supply my vendors for obvious reasons. You either trust you are getting a good product from us that we will support or not. Don't mean to sound harsh. But I have seen so many ebay posts this year where people buy cheap and come here for support when they have problems. We have seen where Ebay sellers will not take back defective or incorrect items. Bottom line is I recommend new R4's which we stand behind with a warranty and support in needed.

If you have a certain brand you have concerns with and wondering if we sell that brand. Post the brand and I tell you yes or no if we use it.

Hey Tim, thanks for the response! No I don't think that sounded harsh at all. Being someone who only does this once in a blue moon to my own vehicles as needed, I don't really know if any brand is better or worse than any other. You ask around and hear good and bad about just about any of them if you ask enough people. I thought about ebay too, but I'd rather not go that route. I know what's available over the counter at the standard local auto parts places, like the Four Seasons family, and Visteon, and Ready-Aire, and one advantage to going that route is I can put them side by side on the counter and make sure what I'm getting will fit. But that doesn't neccessarily make it the better choice. Guess I'm looking at the thought of ordering a compresson thru the mail with a raised eyebrow, but at the same time, the idea of dealing with someone that sells only AC products has definite advantages as well.

I definitely want to go with a new (not remanufactured) compressor. It's just an old truck, but I don't want to have to spend time and money again on it before I need to.


BTW - Wasn't sure of the ties or connections between this board and ackits and Arizona Mobile Air when I asked the question.

It's cool ask any question you like. I'm sure Ice will post up some information. After all he has two sets of tooling for the R4's. That a joke between Ice and I as some fool kept saying CW had a good set and poor set of tooling for the R4's. They don't and never did according to the information I have.

As far as ordering online. All I can say is if by chance it is wrong. We send a call tag and a replacement. Only ask for a deposit for the second compressor while they other is being returned. We never even capture the funds it just sits in limbo while the item is shipped back. We do this for one reason. When we just sent replacements and a call tag. No one ever sent the other one back.

Saw the R-4 assembly before Delphi quit production. They had a good IMPREX system to inject sodium silicate under vacuum to seal aluminum porosity leak paths.
Saw the aftermarket new and reman production at several locations also. The reman operations all make me shutter, especially the surface finish in the shaft which rubs the lip seal. Basic problem everyone (A, CW & 4S) has is porosity leaks with the R-4 is the gravity cast (atmosphere pressure only) process they all use for the aluminum main housing. All other types of compressors use high pressure die casting.
CW is used by Frigette for new Humvee A/C systems, but not without casting leaks.

The use of a new R4 is by all the means the best method. Most suppliers of new 4's offer a good product.....those made in the US....not too sure about some of the off shore units. Delco and Delphi 4's are no longer manufactured by a GM subsidiary. TRB gave excellent the supplier (major...not some one working out of his garage), after all we are all in this for the 'dead presidents' and selling a product that is substandard is not the most advantageous method to assure a profit. Well it is....if one does not have a warranty or stand by their product.

Buy from a source that will stand by the product...even if the cause of the failure is not the fault of the product......and history has shown that most failures are not the result of the product....but of a possible installation error. Buying from ebay....mmmmm......that sounds like finger nails on a chalkboard.....although may be initially less....but if the unit fails....and the supplier fails to replace....the cost begins to escalate rapidly.

What ever source is decided up...and ACKits is a great location....the best method to insure a successful replacement repair is to do the repair correctly...forget the short cuts...just do all that is necessary...after one likes doing things more than once....OKAY!!!!!...maybe some things more that once....but A/C repair is not one of them.
Insure that the system is clean.....use the correct lubricants....evac and...most important....make sure the darn thing is recharged completely. Make sure the engine cooling system is up to par and all components are functional.
Good luck !!!!

Trusting the supplier is a good point. It's not that I don't trust the generic over the counter auto parts houses, but that's just one of thousands of car parts they sell, it's just a tiny part of their business. AC is not what makes or breaks thier business. Only makes sense that a company based on AC would tend to sell what they trust. From what I've read, the R4 isn't (wasn't) one of the better designed compressors out there, guess that's part of what makes me not want to just run to the parts store and buy the cheapest one they have that will bolt up. It's just my old truck so I'm not neccessarily looking for the best money can buy either, just want a good one. I'll probably be talking to the guys at ackits in the next day or so.

Thanks for the input!
