What should I look for in the new (used) engine. My wife blew the original engine when the temp. sensor blew out. I have several sources for the engine, just need some tips on which one to get. Any help is much appreciated. I look forward to learning from you guys! My car has about 150,000 miles on it. Engines I have found were quoted with anything from 40k to 150k. Thanks again for any help.
