Thermostat Temperature 200tdi

<< < (3/5) > >>

Mark2Disco:
yes but engine does not get hot enough
so heater cant get any hotter until engine is running hotter

Vauxuki:
Running an 88degree stat should be enough to kick out a decent amount of heat, provided the heater matrix is working correctly, at the end of the day, it is only a heat exchanger, and they do become less efficent as they sludge up over time, exactly the same as radiators do.

If you would like to make your engine run hotter then go for a hotter stat, i believe they are available still.
Personally, i wouldnt want my diesel running over 90 degrees, specially a turbo'd engine.

Mark2Disco:
just been looking at rave cd and shows a water valve on the heater hoses
maybe thats not opening fully
do you know anyone thats got a good heater in their disco
seems a common complaint

Vauxuki:
I will let you know next week.
My disco had a brand new matrix fitted approx 6 months ago.
I am just finishing fitting the LD28T so will see how well it works on the diesel, was working well with the v8 when i removed it.

the heater in my 200 disco is brilliant. i have to turn it down alot to make it more bearable.yup its that good. i had to change my heater motor not that long ago and believe me when i say this " if i can anyone can ". its a dash out job to change the matrix but its the same to do the motor aswell. i had the same problem as you when i changed the motor. the gauge wouldnt rise very far at all. even booting her up a long hill it still didnt get very warm. so i replaced my thermostate with a new 88deg one. it was better but not brilliant. so i disconnected the pipes under the bonnet to the heater matrix and pushed the hose on the outlet. i let it back flush for about an hour. and then did it the other way.

you wouldnt believe the difference. give it a try and let us know how it goes. no harm in trying  :wink:  :wink:  :wink:
