Hey everybody, so I am having a few most likely related issues with the cooling system on my car.
First off is a regular exchange of coolant between my overflow and my radiator. One drive the radiator will be full and the overflow empty, the next and the radiator will be low and the overflow full. If I try to add coolant to them in either situation it simply burps back out and on to the road next time the car warms up.
Next issue is my temperature gauge seems to wander around randomly after the car warms up. It will go almost to the red and stay there for a minute or two then come back down. The car does not seem to show any normal symptoms of overheating in these situations, like boiling in the radiator, blowing coolant lines etc, and it will do it at both idle and normal driving.
Third issue is I only get intermittent heat when the car is warmed up, it will blow hot for a bit, then fade to cold, then eventually back to hot again. Typically it stays cold more than hot.
Things I have checked: I have checked for system leaves, and have not found any. I am not burning coolant or loosing any coolant beyond what it burps out when I top it off. My heater core des not leak. My vsv controlling the coolant to the heater core actuates correctly and is receiving appropriate vacuum. My fan clutch appears to be in working order. And all my temperature valves and sensors seem to be working.
Things that change prior to the issues: I replaced the coolant elbow at the back of the head and the elbow from the water pump to the rail on the exhaust side of the engine. I also replaced several cracked vacuum hoses on the intake, all routed correctly as per the tsrm. My charcoal canister intake hose crumbled to dust so I capped the vacuum line off the goes to it.
Any help is much appreciated, thanks!
