I was thinking there may not be an expansion valve?


Likely an orifice tube in the engine compartment, no expansion valve.

Whatcha got? For sure any expansion valve would need to be removed first.

Re: 1997 Sebring 2.5L A/C warm (details inside)

Re: 1997 Sebring 2.5L A/C warm (details inside)

When the engine/compressor is running, the low goes to about 35 and the high to about 175 and stays there constantly. The compressor never turns off. What rpm are those pressures measured? Should be like 1800 rpm. There are no leaks. Hmmm - "famous last words". 175 is low for high side pr...

Re: Help! Complete Rebuilt A/C Pressures Wrong

I've used Smart Automotive in north Phoenix for over a decade, for any stuff I haven't been able to do myself (I do well over 90% of my own maintenance and repair). They are honest and reliable.

Re: Help! Complete Rebuilt A/C Pressures Wrong

I used the Autozone loaner R134a service gauge kit and electric vacuum pump up near Prescott, when most my own stuff was down in Phoenix. I felt both were pretty good units. I used my own can tap though, so not sure why you had an issue with the kit's line. Currently my PSI readings are 34/340 (low/...

Re: ac keeps blowing orings

I recently encountered similar on my 1998 Nissan Frontier after my high pressure line developed a pinhole and I bought a replacement line, have a thread on this on this site started about late June. For me, it turned out that the aftermarket part was made incorrectly, and the metal end fittings woul...

Re: finding hoses for r12 to 134a conversion

May not be perfectly by the regulations, but technically one could leave the fittings as R-12 fittings and use the R-12 hoses/fittings and add R134a. You'd need to connect R134a to the center hose of the service gauge set. I actually have an R-12 service gauge set but bought a set of short adapter h...

Re: Subaru AC marginal

Hopefully she's looking at one with a 3rd pedal and row-your-own gears. The CVT and overly aggressive electronic throttle in this one combine for a "drunk teenager learning to drive stick" feeling which outweighs any a/c concerns. :mrgreen: Daughter would prefer one with manual transmissi...

Subaru AC marginal

My daughter lives in Flagstaff AZ 7000 feet up, significantly cooler than Phoenix) and she has been looking at Subaru Foresters and Outbacks under 5 years old. I rode in one of each (9am, cars sitting outside), felt that the AC was marginal in performance, even though the vent temperature did get do...
