Hello there,
I currently have a problem with my A2, where the coolant systems is being pressurized, which on long trips make a lot of coolant escape out the overflow hole. I really want this problem fixed because its quite annoying.
I'm suspecting that the head gasket is leaking, but it doesn't show any symptoms other than the pressurized cooling system. There are no signs of coolant in the oil or vice versa. The temperature never goes above 90C, and the cabin heater works as it should, it doesn't take long to warm the cabin.
I have tried changing the cap on the coolant tank, but it didn't help.
Have anyone else had the same problem?
I have ordered a block tester to test for combustion gasses in the cooling system, and maybe that can help diagnose the problem.
I haven't changed the thermostat or the water pump but plan on changing them, in hopes that it may solve the problem.
If the gasket is the problem, is it even possible for me to change it? I have read the workshop manual where they describe the procedure and it doesn't seem too difficult. But the studs that hold the head, don't they go all the way through the block and keep the bearing caps in place? Because in the SSP 223 manual it says that the bearing covers should not be removed because it will warp the engine block from my understanding. So can i remove the head without removing the bearing caps.
I hope someone can help, Have a great day
