trendkill Posted March 4, 2011 Share Posted March 4, 2011 A friends 90 is overheating having just had a 200tdi disco engine fitted. Put a new thermostat in & checked all the pipes allow water to circulate ok today but its still getting bloody warm. Im only familiar with v8's so haven't a clue with this!! He is coming round tomorrow so if anyone has the 'top 5' things to check?? Or a point in the right direction that'd be grand! Thanks in advance....

voevod Posted March 5, 2011 Share Posted March 5, 2011 when you say it's overheating,do you mean the temp gauge is reading higher than it should?was the 90 a 200tdi also?did you change the temp sender on the thermostat housing to accomodate the difference in engine?

trendkill Posted March 5, 2011 Author Share Posted March 5, 2011 I haven't done anything to do with the engine conversion. Guessing he hasn't changed the temp sender. The engine seems like its warm and the guage is reading over the red after a 2 min drive! Quote Link to comment Share on other sites More sharing options...
landroversforever Posted March 5, 2011 Share Posted March 5, 2011 try swapping to the old engines' temp sender (if the thread fits) that should show if it is over heating or just gauge playing up with the new sender. 200's arent hot after 2mins, or even 2 miles!! unless something is very wrong!

western Posted March 5, 2011 Share Posted March 5, 2011 a common problem when a Discovery 200tdi is fitted to a 90 or 110, the Disco temp sender isn't matched to the 90/110 temp gauge. Quote Link to comment Share on other sites More sharing options...
trendkill Posted March 7, 2011 Author Share Posted March 7, 2011 Has had a new thermostat fitted, temp sender and temp gauge. Top water hose feels fe***ng WARM! Bottom hose feels alot cooler...

doda456 Posted March 7, 2011 Share Posted March 7, 2011 Heres my 2 pence worth: The temp gauge and sender need to be matched. if its a defender temp gauge then you need a defender sender or just fit an aftermarket one that has a reading in celsuis not the usual landrover vagueness . Testing water pump is easy take off the elbow hose from top of the pump, remove stop solenoid and then spin engine and observe the fountain. and it should be top hose hot, bottom hose cold i think.
