Complex engine very expensive parts (friend of mine has two timing belt job is very expensive) he had head gasket problems on both cars that I think he takes great car of but puts a lot mileage on. Overheating problem could be caused by many things a stuck thermostat, incorrect fan operation, restricted radiator of head gasket issues.
my 95 did the same thing check the radiator
