Title: Temperature gauge on the up?
Post by: woolley11 on 18 March 2015, 22:02:40
My 3.0 MV6 temperature gauge shows average/ middle reading  when driving along with no traffic in front. But if I follow someone even at speed, the gauge goes upto 100. I assume this is the lack of air ramming into grill.

Obviously in heavy traffic it moves upto 100 or so.

I use the heaters to pull heat out of the system but wondered if rad is silted or some other problem?

Definite possibility - either corrosion related  or possibly oil from a failing oil cooler.

Any signs of oil in the coolant header tank?

Thanks for that - no oil apparent in the water system and no loss of oil from looking on dipstick level

I'll get it drained and flushed and see if that does any good  :y

Air con on or off and are all the fans working as they should?

If the radiator is clagged up with hard deposits then a simple flush may not make much difference, you may need to use a descaler like Fernox. Check that the fans work first though (bear in mind that if the radiator is furred up then the thermostats in the radiator will also be covered in crud and less responsive than they should be)
