My vehicle has recently had a full engine rebuild. Just recently I noticed bubbling in the expander tank after switch off. I took the vehicle back to the mechanic who did the rebuild and he referred me back to radiator specialists. They tested the cap which was fine but noticed that where the cap fitted the cap fitting area was warped and said that I needed a new radiator.
I need a second opinion. I have a new thermostat as well as a new water pump. I have done all the known tests for a blown head gasket which proved negative, I realize that due to the loss in pressure coming from a warped radiator head that this could well be the problem. The temperature gauge does not show overheating.
Would I solve the problem to buy a new radiator or could their be a problem with the viscus fan. There is a slight loss of coolant.
