waynos 0 Posted August 2, 2009 got the 1.8t installed at last and it starts and runs fine. However once up to temp and the thermostat opened, the coolant level starts to rise out of the expansion tank. Thing is the car isnt over heating (sat at just above 90 on the temp gauge). first thought was an airlock but i thought all the air was out. Another thing is my fan didnt cut in but once i turned the engine off it did? strange. Topped up the coolant and started the car again.it got up to temp again and all was normal, my dad flicked the fan and it started spinning as if it was stuck (so i know i probably need a new fan and possibly new rad fan switch) Would the fan not cutting in cause the coolant to start rising up out the expansion tank? i know that sounds a bit daft but the engine isnt overheating Quote Share this post Link to post Share on other sites
Jay2 0 Posted August 2, 2009 Might be worth checking the seal on the expansion tank cap? Had the same problem of the coolant gushing out on mine after flushing and putting some new stuff in. I'd crimped the rubber seal while taking it on and off, causing a lack of a seal under pressure. Hope its as simple as that. :shrug: Quote Share this post Link to post Share on other sites
waynos 0 Posted August 2, 2009 it think you are right jay,ive got the cap in front of me and was looking at it for ages. Didnt seem to be broken until i clocked that the rubber o- ring has dislodged itself out its groove. so my coolant system wasnt fully sealed. Going to get a new blue one tommorow as i have the black one and have heard they are poopty. Quote Share this post Link to post Share on other sites
Jay2 0 Posted August 2, 2009 :clap: Aye, had me and mates baffled, took it to the local garage and they too were baffled until he suddenly thought to pressure check the cap, turned out it was only a small crimp but enough to not seal fully. Changed mine for a blue one and had no problems since. :salute: Quote Share this post Link to post Share on other sites
