Hi guys,
Been a while since I've been around. Posted this problem earlier this year, but didn't get any responses. Figured I'd give it another shot since I'm back under the hood.
I'll try and keep it short:
Bubbles in the coolant overflow reservoir. Put my air compressor to the cylinders at TDC and BDC through the glow plug hole and wasn't able to see any bubbles in the coolant through the radiator cap. Did a compression check and all cylinders were good. Used a combustion gas leak tester on the engine 3 times and got no trace of a color change.
Weirdest part of all of this, drove it for about a year like this with no trouble. Air just keeps coming out and I just keep ignoring it. I don't lose ANY coolant.
Engine hasn't been warming up lately so I just replaced the thermostat and I'm trying to burp the system right now and I'm reliving this air issue and just thought I'd see if any of you brilliant IDI folks have any thoughts.
My personal opinion is this:
There is a leak somewhere in low pressure part of the cooling system that sucks air INTO the cooling system and pushes it out of the radiator cap. When the car is turned off, this particular spot either seals itself back up or maybe isn't actually under the water level so it doesn't let any coolant out onto the floor.
No one I have talked to can explain this scenario to me. Assuming I can get the air burped out of the system again, I plan to just continue driving this thing.
Cheers guys, hope all's well.
