Hey guys, I just have a couple questions to ask. I just replaced my head gasket because I was loosing coolant in my oil, I went ahead & replaced the timing chain, sprockets & tensioner. 2.2 ecotec. This is my 1st time doing something like this but ive done minor work to my cars & toys before. I followed everything I read. The car started right up & is running very very smooth but it does have a little vibration, more than it used to. Its not like its missing, just a vibration from it running & im just curious?? The other thing is I let it idle for awhile to see if it got hot & it reached 217 then the fans kicked on & cooled it down to 190. While driving it stays between 186 & 200. Is this normal? It never used to reach more than 205 at idle. I have put about 200 miles on it since the job. Thanks for the advice!
