Hey guys this last Friday I had a water pump put in again for the second time in a year and a half. Well Saturday I was driving home and my check engine light came on, I didn't notice right away but my car was over heating. the gauge was maxed out, I popped the hood and it was steaming like crazy. The mechanic left the adapter on top of the radiator and never put the cap on. My question is did this cause any long term damage, even if he said there was none right now. A friend of mine said it cut the remainder of the engine life left in half. My car already has 135,000 miles on it. I was planning on going turbo this summer, nothing crazy just like 7 or 8 psi. Any help would be great thanks guys.
