kris99 0 Posted May 18, 2009 Hi folks, Quick wee question here. Whenever I turn the engine off after a drive I can hear all this gurrgling coming from what sounds like the collant tank. It only last for about 5 seconds or so. The heater matrix was done about 3 months ago, however there is no problems with the heater, mist, and no damp carpets. The coolant level does sit at about 90-100 however. Any ideas what this gurglging noise could be and how to fix it? Cheers Kris Quote Share this post Link to post Share on other sites
Kevin Bacon 5 Posted May 18, 2009 What engine? VR6? Sounds like you have a small air lock in the system which the aux pump is moving around when you turn the engine off. Quote Share this post Link to post Share on other sites

craigowl 0 Posted May 19, 2009 Yes - aux coolant pump (electric) switches on to prevent localised hot spots developing and consequent warping of head, so I believe. I can hear mine - dont know enough about it to confirm there is an airlock as pianowire says. Quote Share this post Link to post Share on other sites
