I’m looking for some advice on a cooling problem I have been fighting with. For whatever reason, my cooling system pukes around a gallon or so of fluid during warm up.
I have a 69 Camaro with a 350, a Weiand high volume aluminum water pump, and a 3 core copper radiator with a 13 psi cap. Every time I drive the car, it pushes a bunch of water out the overflow when it warms up. Once the thermostat opens, the car seems to run fine and doesn’t use any more water.
This weekend, I started the car without the radiator cap on to see what was going on. Long before the T-stat opened, I could see water vapor coming off the heater hose going into the intake. The upper radiator hose was cold, and the temp gauge had not begun to move yet. However, the level in the radiator kept rising and it started pushing water out. Once the T-stat did open, the level in the radiator dropped to about half full.
Does anybody have any idea why the car would be doing this? I changed the cap out for a new 16 psi unit and it’s still doing it. It does not appear that the lower radiator hose is being sucked closed. Could it be something with the heater core? I’m pretty much lost as to what is going on.
Any advise you guys have would be appreciated.
Thanks
Marty
