HI, on my 2002/ 330I I my coolant was slowly disappearing , yesterday it blew the hose of the bleeder housing . ok I installed new clamp was ok but start to overheat , noticed that upper hose was very hot yet lower hose bit warm ( it could be warm from the engine heat) so it looks like a thermostat? or does the overflow tank has anything to do with?
I need to fix it today please advise
Sounds like a trip to ECS is in your future. Definitely sounds like a thermostat. How many miles and has it had any of the other coolant components replaced? If not , you may wanna just do water pump, thermostat and expansion tank while in there.
OK, thermostat replace and upper rad hose all good now , ( used World Pac parts aftermarket made in Germany by Wahler) other coolant parts replaced 2 year ago. now waiting what else will broke down
Don't guess......
