As some of u guys know I changed last month my thermostat with success. But ive been having some problems.
1st. when the coolant expands it wont expand like stock the flow is intermitent like comes and goes continuous i thought bleeding the system might do the trick? i tried finding a bleed screw on the coolant hose that is on top of the engine under the engine cover but there is no screw? i proceeded with the heater core hole in the tube by removing it until its clear from the nipple and turning the engine with the heater at full blast. nothing comes out though no coolant. But as soon as i rev the engine coolant squirts from the little hole. Ive try milking the upper radiator hose and you can see coolant squirts a bit. THe thing with all this is that the temperature in the cluster acts weird sometimes it warms to the middle and sometimes drop cold. I changed the thermostat because i was having this problem with the one it had. oil temp gets normal though. Oh and no codes coming up on vag com. My car is an AWM engine a4 1.8t 2001

Need help guys!!! Im upgrading the turbo this month

You need to login for that video.

It sounds like you have an air bubble in the top of the motor?

When you bled the heater core did you raise the coolant reservoir up about 6 inches as per Bentley.

You do that then bleed at the core, engine not running. You might need to do it a couple of times to get water behind the thermostat.
