gav_113 0 Posted July 15, 2006 Report Share Posted July 15, 2006 hi peeps i need ur help again!right today i went my mates and when i pulled up i could hear bubbling from my header tank. so i popped bonnet and water was bubbling out of the over flow on the tank.i waited for it to cool and refilled tank. i thought a air block could of caused this? because recently the two water pipes on the oil cooler split? and i had to replace them.later i went home and it done the same! :@ my mate said it could be 3 things.1-relief valve thing in header tank?2-head gasket?3-header tank cap?has anyone got any ideas? (i) the car hasnt lost any power, and pulls like a train!is there any way of checking if it is the head gasket without taking the head off?also both fans are working, and the water temp is still running at normal levels?thanks......
