Good stuff here. Thanks.
And congrats on the successful service. Few things are more satisfying than successful DIY projects.

I have 5 older Dodge vehicles i maintain. The oldest being 1999. Mostly Caravans.
I also have a 1996 Toyota Tercel that will need a full AC service soon.

All I saw was AUG 18 ...and thought it was yesterday. oops :-)


I'm the OP and I see you've found my old thread on this issue. Long story short, I had an aftermarket TXV calibrated for a plate fin evaporator on my OEM tube/fin evaporator. This mismatch I ...

Hello everyone,

I just wanted to post a follow up to my 1993 Jeep Cherokee XJ A/C repairs. (original post here: https://autoacforum.com/viewtopic.php?p=25581#p25581). I had some service valves leaking oil at the compressor, so I needed to open up the system. I recovered the refrigerant from the ...

The original condenser was a Serpentine design that worked well.

If it was replaced with an aftermarket part of a different type, it is hard to say if the condenser is up to the job.

Jeep went several years where they could not make up their mind on fans. I believe your 1993 should have an ...

I didn’t take a reading at the vent to see what it dropped down to. I would take a guess that it dropped about 10 degrees from 70 ...

Thanks for the reply! To answer your questions:

Yes, all manifold hoses were purged before charging. I vacuumed for 3 hours and the system got down to 29 in Hg. I did not have a micron gauge to get a precise reading but after evacuating for a while I isolated the vacuum pump from the system and ...

I’m having A/C issues on a 1993 Jeep Cherokee with a 4.0L engine. The background on this Jeep is that it had an original R-12 system that worked well up until it was wrecked two years ago. The wreck damaged the condenser and I believe this ultimately led to it leaking out all of the refrigerant ...

I am by no means an expert here, but having some familiarity with this A/C system (have an ’07 TL Type S with the same J35A8 engine, and is probably very similar A/C system to that) I thought I would chime in. I had an A/C related issue on that car in which the A/C clutch relay failed in the closed ...
