Thanks for your help, very informative. I have ordered the cool harness and noted that a 300TE owner said that it worked great on theirs. I've got my fingers crossed! My car is in beautiful condition and I would have hated to get rid of it---but with two little ones, i can't be driving around with an engine that has bad overheating problems. Now I have hope that we can get it fixed!
Thanks again!! I'll report the results after I get the cool harness.
