200tdi heat problem
stefan:
Tim,
My conversion behaves the same, sits between 90 and 100 on a push, just around 88 normally, top hose and stat housing hot, bottom of rad and bottom hose cool, it's a new rad and I know it's not blocked. New thermostat (right way up).
Even when the temp gauge is near 100, I can't say it feels particularly hot under the bonnet, you can normally feel/smell that it's running hot can't you.
So I think the Tim gauge may be a little over optimistic and I don't think it's really anything to wory about. I'm going to fit those twin Mondeo electric fans, predominently to provide cooling when off road, as the fan cowl now cut to fit doesn't quite draw the whole air in over the rad, and may eventually look at removing the viscous fan altogether if the electric ones coupled to a kenlowe thermostat control do the trick.

Hello mate its exactley the same mate i thinks it was me being Paronoid!1
Any way it seems to have cured it self today!! i think an air lock apparant(Bloody Big one and difficult to dislodge).
I was told they were [!Expletive Deleted!] to bleed!!
Any took her off road today and she sat nicley at no more than 60 - 65 Oc with no probs!!
On road she now sits at 85 0c and when pushed 90 - 95 0c so must be ok and when i stop engine seems warm but not as bad as it was the other day..
Could have been a blocked in Engine coolant paths and needed to be run to unblock??
God knows any way its ok again till next time ..but thats Land Rover for ya!!
Hey when ya fit that Fan Details ASAP Begining to end .

Fitted the Mondeo fans, pictures attached and on my new updated 200Tdi conversion page of my website http://www.90county.co.uk. Basically they have to be placed on the engine side of the rad as they are marked with a distinct direction and will then pull air in through the radiator, and need the bottom corner trimming away to fit. They have to go in on a slight angle to clear the top radiator hose, but that leaves each of the 2 fans covering the radiator and most of the intercooler. I connected the positive feed of one fan to the other, than ran a feed to the Kenlowe thermostat unit, from there a wire then runs to a fuse on the bulkhead and then in and connects to the position II connector on the back of the ignition switch. Both fans have their own separate wire to earth, all wiring 35 amp and the fuse 30 amp. I made a bracket up to bolt in to a redundant hole on the passenger side where the old radiator bracket used to be, and then a bracket on the drivers side which comes up and clips in with a radiator bracket clip as per the photo. I just made the brackets from redundant bits and bolted them in to existing holes. The fan unit is very secure with just two top mounted brackets holding it in. I'm going to get a heavy duty switch and put that where the old choke cable was, connected in between the ignition switch and fuse, that way I can disable the fans when using the 90 off road in water.
They seem pretty powerful and when they are both running, you can feel air being drawn in when you put your hand in front of the grill. The fan unit has some kind of temperature sensor on it, I guess by the design it justs butts up to the radiator, and I think if you connect your positive feed via this it might do the job. I had an old Kenlowe thermostat so used that.
So for a fiver plus postage off Ebay, a pretty good bargain!
