bleeding water sysem and lots of sream

dancarthew · Jan 9, 2010

Hi All,
Thanks for the previous help, i've now replaced the thermostat that i hope was causing the previous overheating problem, filled back up with watyer and antifreeze started the beast up without the expasnion bottle cap on, lots of air bubbles and now a lovely warm cab, temp guage went up to normal and stayed steady but the return pipe to the expansion tank from the top of the rad is cuffing out clouds of steam, is this normaql and just because i was running with the cap off?
The Mrs now wants me to sell it as it's high maintenace, please help before i'm forced to buy a bloody audi!!!

The key is to just not tell her how much is costing and get it sorted on the quiet!

The coolant will boil with the pressure cap off. Increasing the pressure has the effect of raising the boiling point of the coolant

Yes it does, 2 degrees for each pound of pressure. But steam should not be coming out of the rad over flow pipe into the header tank, it should be water. It is there for the purpose of letting the coolant expand out of the rad into the header tank. There should not be any steam even if the cap is off.
