expansion tank

[top_driver]

hi, i was just wondering, should the water that sprays into the expanison be spraying all the time or just when the rpm is increased, it is an e46 323i

The Coolant re-circulates Top. are you still having trouble with your BM?

[top_driver]

well i lowered the level of my coolant because there was too much pressure in pipe now there not as much pressure, and now it only recycles when with increased rpm

[TWR]

Thats right, it will, check the level on the header & keep to it.

brilliant, thanks, was getting worried there

[TWR]

Providing you keep your eye on the level you should have no probs.

grand, ye i think the level was too high, and it found ways to leak out at top of expansion pack, it seems ok, i am going to wait till the engine is cold and check the level, i will remove overflow valve to attain proper level

How do you know that your coolant pressure is to high or low? How will removing a crucial part like an overflow valve help?

It seems that your coolant system needs bleeding properly.

It is crucial that it is correct, read this..............

i mean remove the valve temporarily to allow a correct level to be achieved, have engine cool take off the valve, the water is free so level lifts to the correct level, and put in the correct amount, i have done that and the pressure has been relieved
