Hey guys, my first post here as a defender noob,
I have a problem with my td5 defender if anyone can offer done advice?
did my first long run in the defender, apporox 250 miles of motorway driving, after returning home, I've gone to do my usual under bonnet checks to find my radiator had expanded right up, nearly to touch the bonnet, I presume the water in the radiator has boiled for what ever reason.
After replacing the radiator for a new, less bent one, bled the cooling system to find only half the radiator has got hot and all the pipes except the return hose from cold side of the radiator to the thermostat.
Then I presumed the thermostat has sized causing the loss of flow and boiled radiator water. Replaced with new thermostat, bled up, no better, half cold radiator and one cold pipe, next jumped to the conclusion that the water pump can't be powerful enough to pump the water.
One replaced water pump, still no better.
Can someone offer some advice before I slowly rebuild my defender for what probably is a easy fix??
cheers guys,
Lewis
