Toyota Coolling System Problem

TOYOTA CAMRY

1989 Toyota Camry 185k miles 2.0l engine. I recently change water pump, radiator, hoses and flushed system with radiator flushes. The engine temp goes high after a few miles and coolant overflows thru the resevior. While driving the temp goes up then down intermittently. I can see spills of coolant next to the reservior. With engine cold, radiator would be empty of coolant and reservior would be barely empty. My friend took out the thermostat but the problem still exists but the engine temp goes up slightly slower. Car runs though in the best condition for its year. Thanks

I didn't see where you CHANGED the thermostat. And the problem with running an engine without a thermostat is that the coolant is constanly flowing. This means that the cooler fluid doens't stick around in the engine to effectively cool it, it just flows by, not absorbing much of the heat.
It could also be a problem with the radiator cap, it could be letting the coolant out before reaching the right PSI. Your cap should probably be rated about 13 PSI.
So I would start with the cap, but if you still have the therm out you may want to just drop a new one in as well.
Also check to see that you are bleeding the air out of the system proberly. Some Toyotas have a banjo bolt style bleeder on the upper gooseneck, the piece the upper hose attaches to.
