I have a VN V6 series 2 and the over flow bottle keeps boiling over when I turn the car off after 20mins or more of driving, the bottle shakes like it is going to pop the cap off, and than the water comes out the hose until bottle is empty. any ideas?
engines getting too hot, is the thermo fan kicking in and what temp is the gauge sitting on? by the sounds of things there may not be enough water in the cooling system and/or you could have a air leak causing the coolant to heat up and booil over in the overflow once you switch it off..
bleed the air out there is a screw on ya thermo housing loosen that off as you fill the engine when ya finish filling wait until there is a constant stream of water and do the screw back up mate if ya dont let the air out it is a real pain in the a55 trust me lol cheers
Thats the way to do it but make sure you dont have a permanent leak which will have you back at square one.. do a leak test a cooling shop will do this for nothing.
