Farky Posted October 6, 2017 Share Posted October 6, 2017 Hi all, Need some help again Little while ago a hose split coming out of my heating matrix, chucking coolant everywhere. Replaced the hose, flushed the radiator and cooling system and refilled. Ran well for a couple hundred miles but now is overheating everytime I run it. Hoses out of the radiator stay cool but pipes out of the heating matrix are red hot. Wondering if when the hose split the water pump ran dry and knackered itself. Any help greatly appreciated before I start changing parts Thanks Quote Link to comment Share on other sites More sharing options...
Puffernutter Posted October 6, 2017 Share Posted October 6, 2017 Could there be an airlock in the system? Is the heater getting hot? (OK - it's a Defender, is it above tepid :-) Cheers Peter Quote Link to comment Share on other sites More sharing options...
Farky Posted October 6, 2017 Author Share Posted October 6, 2017 Yeah that was my first thought, but if it is an airlock I haven't been able to clear it. Its actually belting hot air through the blowers (hotter than its ever been before) Also worth mentioning that I tested the stat in a saucepan and it was opening and closing Quote Link to comment Share on other sites More sharing options...
Puffernutter Posted October 6, 2017 Share Posted October 6, 2017 If you're in the Trowbridge area I've got a cooling pressure testing kit you can borrow. Cheers Peter Quote Link to comment Share on other sites More sharing options...
Farky Posted October 6, 2017 Author Share Posted October 6, 2017 Thanks a lot, bit far for me but appreciate the offer. Will persevere with trying to clear it if its an airlock, if no luck I think it will be a new pump. Don't suppose theres any tell tale signs of it being the pump without stripping it out?

Puffernutter Posted October 6, 2017 Share Posted October 6, 2017 Apart from noise - no! Also be careful on removing it - the screws shear very easily! Cheers Peter Quote Link to comment Share on other sites More sharing options...
