I have a 1968 mustang with a 289 engine. It normally runs pretty well, but when I took it out of storage this year it started overheating and then coolant started flowing out on the floor infront of the passenger seat. What happened and how do I fix it?
Disconnect your hoses and put a short loop on your engine to bypass the heater core. If your car runs good and you don't overheat/loose fluid then you need to replace your heater core before winter. Otherwise you have other problems and you need to look for the new leak or thermostat.
I agree. It is probably the heater core. If the hoses are attached outside the firewall then it probably won't be a hose. If the are attached inside the car they could be leaking at the end, but my money is on the core.
