squeak Posted April 30, 2010 Share Posted April 30, 2010 Hi everyone, when cruising on the motorway at 70 the the water temp on my Disco 200Tdi creeps up to almost three quarters on the temp guage, yet at 60 she will stay all day ay between a quarter and half. She has only done 108,000 miles but also struggles a bit on hills. Hope one of you guys can help. Quote Link to comment Share on other sites More sharing options...
Fantic Posted April 30, 2010 Share Posted April 30, 2010 Check the back (engine bay side) of the radiator. The fins can get blown out quite easily and it's unnoticeable from the front. Even just a few missing can cause some degree of overheating ... Quote Link to comment Share on other sites More sharing options...

keithjh Posted May 1, 2010 Share Posted May 1, 2010 Sounds like a partialy blocked radiator I would take the rad out, simple job and have a good look at what the fins are like and also give it a good back flush to try to remove any blockages carp build up etc Regards Keith Quote Link to comment Share on other sites More sharing options...

Thys Posted May 2, 2010 Share Posted May 2, 2010 My Disco !1 300 Tdi Auto's temperature did the same when I had 3 passangers, and a long 1.5 mile climb. Radiator was re-cored a while back and the thermostat new, eventually it was the viscous fan playing up. I borrowed a locked one, and the temperature was actually lower, replaced the viscous hub, and all was well again. Quote Link to comment Share on other sites More sharing options...
