Recent Overheating Issues!
 

Started this thread on m.net the other day when my car out of the blue started overheating gradually. I know it annoying to link to another thread but I was wanting some of you all's opinions on the issue.

Pull your spark plugs tomorrow and see what they look like. If one of them is cleaner or whiter than the others you could have a blown headgasket.

it still sounds like you have an issue....either the sender to the dash is failing (doubtful) or you have a headgasket issue.

since it's still spiking, it should never go past 12° o clock (especially with fans running 100%), i have a feeling it's the gasket. check your coolant level again to see if it's lowered.

I'll have to check them tomarrow.....what would cause that?
