Saturn Repair Problems? Ask a Mechanic for Answers ASAP
Hello Michelle, my name is Bobby. Thank you for the question. There are a number of reasons as to why this will occur. Since the engine is getting hot we need to determine why. I would like for you to see if the fans are coming on as the engine starts to get hot. That would give us a good starting point. If they are and it is overheating then it is possible that there is a restriction someplace or that it may have a small leak in the head gasket. If the fans are not coming on then we can test the circuit with a voltage meter. As for the leak, the system needs to be pressurized to see where the leak is. It may be as you mentioned the pressure cap on the reservoir releasing pressure as it gets hot. Please let me know if you guys can check the fan operation and we can proceed from there. Thank you.
Sorry for taking so long to get back with you. The only place it should leak is from the coolant tank when it gets really hot. If it is coming from anywhere else then that definitely needs to be found and repaired first.
Please let me know so we can continue from there and get this taken care of.
If the engine is staying cool when you are on the highway then it is more than likely a fan issue. If it is getting hot even then you may have a leaking head gasket. You can test to this with a block test kit. Most auto part stores sell them or loan them out. If it comes back with a positive result then you can try the block sealer. The only one that works good is the Bars Leak with Carbon Fiber.
