I just had a cold start sputtering...loss of coolant (maybe 1-3 ozs (at the end)). This happened after a substantial overheat and radiator neck blowing apart at the end...before I knew anything about cars!
In the end, I don't know what tests the shop did, but they showed me the cracked head.
I wasn't overheating, but I wasn't losing a lot of coolant either and kept it topped up. I went for a few months until I knew it was something serious. Then, 6 months after the work was done, some idiot totaled my car! sigh
As desperate as this sounds, in comedy, 'likes' and 'views,' 'friends,' and 'retweets' really help. If I've ever helped you, please help me by friending, liking, viewing, and retweeting. It makes others think I have a following...it'll take you a minute or less. If you could, I'd really appreciate it!
