"Expensive" is a relative term. It all depends on your financial situation. For some, it might mean not paying other bills this month. For others, it's a drop in the bucket.

How much is it? Again... depends. DIY or mechanic? If the latter, is it the dealership or an independent shop. It also depends on how trustworthy that shop is, and how greedy they are. I'd say anywhere from $125 to $600.

Roger thanks for the feedback on my temperature gauge, is that temp sensor an expensive fix?
