Four problems related to engine cooling system have been reported for the 1997 Plymouth Neon. The most recently reported issues are listed below.
Blown head gasket. Oil in cooling system. Contacted Chrysler, no help there. I still owe $5000 on a car with a messed up motor. I believe Chrysler knew these gaskets were defective and did nothing about it. There was a TSB put out in 1998. Why weren't owners notified of the problem. It's alot cheaper to replace the head gasket rather than replace the motor. I called the 1-800 number and they don't want to talk to me. Same with the dealership I took it to.
Radiator fan relay failed which caused engine overheating and then water pump failure due to defect in the anti-freeze resevoir - the nipple for returning anti-freeze to engine was molded closed. Dealer did not advise me of recall on relay and wants me to pay a fee to inspect resevoir. Refuses to pay for water pump.
Vehicle overheats due to the relay sticking in the off position. The engine gaskets are leaking oil which is spraying onto the exhaust system. The manufacturer has been notified.
Thermostat and water pump failed.
