Venatus 2 Report post Posted August 18, 2011 Ok, so my m10s radiator is very very rotten, have scored an m42 radiator for rather cheap, but has the 3rd small pipe off the expansion tank, which seems to be some sort of return from the heater core off a t junction. Have tried shoving the m42 radiator in, mounts up all fine etc, but seems to get no flow whatsoever through the radiator so cant even bleed it. Shoving a hose down either end seems to show the radiator isnt blocked, but flow just doesnt happen, and then its fine when the m10 radiator is back in. Any ideas? or just deal with the stupid rotten m10 radiator until engine swap happens? Cheers, Quote Share this post Link to post Share on other sites
