vin diesel 0 Posted October 1, 2006 Report Share Posted October 1, 2006 Can anyone help with this problem? My beast is loosing water through the top of my expansion tank, i've changed the tank and the cap but it's still no good. The previous owner only had water running through the system i was wondering if the fact that there's no antifreeze in the system is causing the problem?? Temperature gauge does not move so doubt that it's head gasket!! Mail me if you have had the same problem. Link to post Share on other sites
matth76 1 Posted October 2, 2006 Report Share Posted October 2, 2006 If you're losing water and no obvious leaks then that is possibly(unfortunately) a sign of a fault head gasket... Or it could possibly be a temperamental water pump (which may need replacing) best bet is to ring Stealth or The Phirm and see what they say. Link to post Share on other sites
rodney 17 Posted October 3, 2006 Report Share Posted October 3, 2006 Might also be a blockage if its coming out the tank. Does it kick more out when you rev it and then drop to a lower level as revs drop?? Might be worth popping a flush through and draining the system. Only problem is.... if the blocks hiding a leak...... Either way its something of the list Good luck Link to post Share on other sites
c4mbl 1 Posted October 3, 2006 Report Share Posted October 3, 2006 surely if it was a blockage, the temp would be creeping up a bit more than usual too though. Link to post Share on other sites
jezmoz 0 Posted October 3, 2006 Report Share Posted October 3, 2006 i had a leak on mine was the water pump, also check all coolant pipes for cracks etc and the thromstat housing, it's not always the head gasket Link to post Share on other sites
dellert 0 Posted October 3, 2006 Report Share Posted October 3, 2006 and the Auxillary pump hiding at the back, and make sure it not overfilled! With the cap off you should see flow coming into the tank from the little pipe at the side of the tank. What colour is the water now? Link to post Share on other sites
latestarter2 0 Posted October 15, 2006 Report Share Posted October 15, 2006 got same prob with my VR6 corr....had the water checked for combustion gasses and its come up positive so sounds like my head gasket is going..so its a warranty visit for me!!!. Link to post Share on other sites
juliet 0 Posted October 19, 2006 Report Share Posted October 19, 2006 A pressurised system can be either a head gasket or an air lock. For the head gasket i would run the car from cold with the expansion cap off and as the car warms up, the water exspands filling the tank up to the top. a quick 10 to 20 second blip on the throttle at high revs would in the case of a serious Gasket leak send water spewing over the top and on some cars iv seen it gush up in the air. Another trick is to take it to a garage with a old style exhaust emissions tester ie a small crypton type tester with a sniffer pipe and place the snifer pipe in the expansion tank. If the reading on the co2 and hcc goes sky high this also indicates a blown gasket. As for air locks i can only suggest bleeding the system via bleed screws or by removing cooling pipes at the highest point on the engine. Dont be dicouraged i often work part time in my friends garage and iv seen air locks that have taken a hour to remove. Link to post Share on other sites
