i just bleed my system and added antifreeze though it would stop my heating problem. i changed the thermostat and when i hit 90 celsius i get some strong pressure on the upper radiator hose going to the thermostat housing. i use a 324td radiator which is huge. my temp is above the medium mark when my thermostat opens maybe it's f-ed or something. but why do i have so much pressure in the upper hose i just loosened the collar on the small diameter hose that goes to the expansion tank and it spilled coolant around it.could the small diameter hose be clogged?

Clog somewhere in one of the hoses? maybe an air bubble? I'd flush the whole system out and try again. Or squeeze the top hose a bit and try and massage them a bit and see if you can move the air bubble if thats the issue

the expansion tank was clogged where the small hose connected, now the upper hose is just a bit hard still seems to have some air not just waterComment
