peachers 10 Posted June 9, 2012 Hi, Got a bit of strange problem with my corrado vr6 where it intermittently loses some coolant. It doesn't happen very frequently but has now happened about 3 times in the last 6 months, the most recent was today where I had top it up with about 250ml. I had the car checked by garage a few months ago and they ran it for nearly an hour and couldn't find any leaks from the cooling system. Somebody else I spoke to mentioned that there is a plastic flexi pipe towards the back of the engine that can perish and leak coolant when under pressure sometimes. Just wondered if this was correct as there is no other evidence of coolant leaking on my drive or if anyone else knew what could be causing this problem? Cheers, Peter Quote Share this post Link to post Share on other sites
Jim Bowen 1 Posted June 9, 2012 I had a tiny hole in my rad that would only show up after a hard drive, they quite good at sealing themselves and becoming hard to spot. Sent from my X10i using Tapatalk 2 Quote Share this post Link to post Share on other sites

peachers 10 Posted June 10, 2012 Thanks for the replies, radiator etc was all replaced before I bought the car just over a year ago so think it is OK. Haven't had the heater matrix done but was wondering if it could be one of the pipes just due to the small amount of coolant that leaks out? Quote Share this post Link to post Share on other sites
