Tell you what you should NOT do... don't run water through the engine.

I couldn't resist... just went and read through that old thread. Sorry I don't have any real help for you... good luck!

 

Lmao @ that guy. I saw that thread too. What a shame. Hey I'm just gonna run water through an engine in a $40k+ car.
