Honda CRX system build up?

doctorgonzo on Fri July 04, 2008 7:09 PM User is offlineView users profile

Year: 1989
Make: Honda
Model: CRX
Engine Size: 1.5
Refrigerant Type: R12
Ambient Temp: n/a
Pressure Low: n/a
Pressure High: n/a
Country of Origin: Japan

I recently acquired a '89 CRX HF, with a relatively intact but presumed dead A/C system. I'm new to the hobby, but I, at base, want a very well thought out, well-engineered, R134A-based, icy-cold A/C system. I believe the best thing to do would be to remove the old, 20-year-old, unknown quantity of an A/C system and start from scratch. I assume the kit sold for the CRX on the ackits.com website might be a very good starting point, but I'd like to incorporate a PF condenser. In order to provide a solid foundation upon which to build a new A/C system, I plan to remove the dashboard in order to get at the evaporator core case and blower motor housing to clean up, inspect the evaporator core, verify correct functioning of the various components of the system, as well as install new seals whenever possible. So, that's the plan for the first stage of the HVAC rebuild, and I don't have any specific questions, but would like to open the floor to this incredibly knowledgeable forum for any advice, suggestions or modifications/changes I might make to my game plan.

All our systems use a true parallel flow condenser.

See if you have a full-width serpentine condenser. That's what's stock for my '91 Civic DX and the stock system works pretty well on R-134a. Really you don't need to change everything to go to 134a. The condenser is the critical part. If it's a tube and fin you should adapt to a parallel flow one.

You can work on the evaporator by taking the glove compartment off its hinges and out of the car, then remove the evaporator box thru that hole. Any remaining refrigerant will need to be recovered first. There's no need to pull the whole dash. I would suggest doing that to at least inspect and clean the air side of the evaporator because it will likely have a lot of dust and leaves, etc. in it.

TR70 does not do well with R134a. Been more then a few posts over the years with the compressor case with a big hole blown it. After people converted a system with this compressor.

Tim, so what kind of compressor ships with the kit for my CRX (AMA16765-9039)?

Tim,
The engine depicted in the .pdf instructions you linked me to you provided looks like it belongs to a '84-'87 CRX. I would have selected pn.AMA16765-9028 instead, but the mouse-over for that kit, tagged "1988 to 1991" conjures up "1.5 liter 16 valve engine Standard or Power Steering w/o Air Pump", but my engine is an 8 valve, whereas the mouse over for "1988 to 1990" (AMA16765-9039) conjures up "1.3 or 1.5 liter engine Standard or Power Steering w/o Air Pump", which is indeed a model year and engine displacement match, however confounding the fact that the 1.3 wasn't available for the '88-90 models. I have a feeling that AMA16765-9028 is the right kit for the '89 CRX HF, in spite of my engine only being an eight valve, but only you could make that call.
Thanks,
