[Vwdiesel] trip with Jetta GTD

Wed Mar 11 20:03:10 PDT 2015

Yeah, I hated those oil coolers. Had multiple problems where I got oil all
over in the coolant. I would check it by connecting the two coolant lines
to each other and leaving the pipes open at the cooler. Then run the engine
and see if anything gets pushed out. Worked every time for me. Depending on
how it was bad, I think sometimes I had to get the engine warm before much
would come out.

I didn't have much luck with degreaser on cleaning the engine. I found
regular Dawn dish soap to work the best of the 5 or so things I tried. Took
multiple batches to really get it clean, but it did do it.

Have fun :)
