Hey guys... so I've been doing some searching and can't quite find the answers to my questions. I have a 2001 with 121k miles on it. Runs great, no problems. It appears to have been well maintained. It doesn't lose any coolant, the oil isn't milky, etc... It holds a pretty steady 195-210 on the highway and general driving. Am I going to be doomed at some point? Is it rare for them to crack? Is it something that I should worry about before it happens? Any information is much appreciated. Point me in a direction or shoot me your thoughts.. Thanks in advance!
