I have a 2002 PT Cruiser with 60,000 miles that is only used occasionally. The fan that cools the engine needs replacing as does the valve that controls the fan. Also the battery must be replaced. Estimated cost of repairs is $1200 with a slight possibility that the head gasket was ruined when the car overheated which would necessitated another $800 in repairs. Should I bother putting that much money into the car? If I don’t, I’ll need to replace it with something.
I can’t see how a cooling fan, a coolant temp sensor (“valve that controls the fan”?) and a battery come to $1200. You need to get a second opinion. Also they should be able to tell with a high degree of certainty whether or not there is a head gasket problem. Go somewhere else.
