Hello jfklein!

At the same time you're dealing with your GTI slow leak, I also had a slow leak on my 2001 Dodge Caravan.
In my case it was a bad high side port. I was able to unscrew the old one and install a brand new one.
I also found that all the rubber O-rings at the evaporator were all smushed ...

Since this is a Dodge Caravan specific thread.....

If you are working on a 2001 that has the electronic sensor mounted on the expansion valve....

Be extra careful to pay attention to the sensor connector that goes to the air intake bellows at the throttle body and the connector that goes to the ...

IMHO, the advice Cusser posted is 100-percent correct.

If you have the knowledge, skills, and tools to work on the system yourself, I suggest concentrating on potential leakage points first. Leaks could be anywhere, but I would focus my attention on the condenser, the compressor shaft seal, the ...

I never take offense when someone adds on to anything I post as many are more knowledgeable than I. I'm NOT an AC professional, just somewhat experienced and live in the land of AC being used 95% of the time, Arizona.


Should I take the car to a dealership, a shop that specializes in VW cars, or ...

If you go that route, just be sure to get a GOOD UV Light source. Many ...

I maintain a personal inventory of Evap Cores, Condensers, heater cores and A/C hoses for my hobby of collecting and maintaining older Dodge Grand Caravans.

Every time I get a new one I used to wonder if it's got any leaks (Oh, I worry about the AC equipment as well :-).

installing it immediately ...

If anyone ever wants to do this resto on their vehicle HVAC housing, I found a much better way via a smart guy who does this type of thing a lot. He suggested Mann Ease Release. It's sold on Amazon etc. It's a spray specifically made to spray on and release hardened epoxy resins.

This is gonna make ...

You might also want to check the lines running from front to back. They can become corroded, degraded, and can leak, especially if they run through a wheel well.

My co-worker had a Grand Caravan from that era. He had leakage of refrigerant on the lines going/coming from the rear unit, Dodge ...

Option 1: I've never tried either option, but how about spray-on foam-in-a-can, the inexpensive type from your local home center that's designed specifically for sealing around windows? Unlike expanding foam that will fill gaps one inch or wider, the window variety features minimal to no ...
