Project TB2 - Update 3
« on: 06 April 2007, 18:02:58 »
Not much done yet. Still overheating or overpressurising.

Current thinking is that it may be overheating, and dash gauge is wrong. So I've sent tunnie down scrappy to find a coolant sensor so I can Tech2 the ECU to get coolant temp.

While he is down the scrappy, I've been fixing odds and ends inside the car.  Had to put in another climate unit, as the drivers side display was fubar. Fixed up some other stuff around that area as will.

Flushed the coolant through yet again, its all coming out very clean now.


Changed the backbox on the Rover as well, as thats being MOT'd on Tuesday.

I think the rad is a red herring. Carry on with your other thoughts.

Alas, unlikely. Tractors are fairly rare anyway...

coolant sensor / thermostat / and hard pipes -air block would be my line of thought first of all.

Flushed a number of times, and its supposed to be self bleeding, so don't think its airlock.

Stat replaced, old one had been drilled.

And it seems the coolant sensor is not the fault with the coolant sensor  >:(, must be somthing in the loom  >:(. Or ECU  >:(

what did you say the temp sensor was reading again? -40 or something silly?!?!!?!!

You might be right on the over fueling with that.... so if its constantly giving it more fuel would account for overheating. Plus the nakered intercooler, and fans not kicking in...

I think it's all still linking back to that sensor.... or the loom leading to that...

It knows that reading is rubbish, so substitutes more sensible values...  ...possible fuelling incorrectly, not convinced doing so to overheat though  :-/

Intercooler fan isn't there to cool the system ;)  (its there to cool turbo'd air, as cold air more dense, so can get more in cylinders, hence more power)

Well, technically, you didn't get the old one out. Yet.
