    No it won't, the fuel cooler gets flow direcly from the bottom of the radiator, the return from the matrix goes into a T piece at the end of the cooler where it meets the outlet flow of the cooler when the thermostat in that piece is open cos...

    I double checked the coolant flow diagram and i am convinced now that you can simply stop the flow toward the matrix from the top hose with a simple mechanical valve without affecting the engine's cooling nor the fuel cooler's function, cut the...

    Hi, if the TPS live readings are as they should in the ECM inputs(track 1= 0.5-0.8V at idle/4.5- 4.2V at full throttle and track 2 = supply - track 1 all the time) while TPS inputs are wrong in the ABS i doubt that changing the fuel map will help...

    Only the pedal braking will work this way but without power bleeding the modulator once it was empty of fluid will affect the correct function of all the active braking modes(ABS, TC, EBD, HDC) cos air will be trapped between the OV's circuits...

    Yes, you can for test just the ride heights might be a bit different but if you connect it and the compressor will not run like with the original you know that's it. If nothing changes you should swap the fusebox... what ever you swap disconnect...

    Hi, which fuse exactly? No, at this point the first suspect is the fusebox or in the worst case the SLABS ECU unless it's a wiring issue somewhere and that coud be a nightmare.

    sierrafery replied to the thread Disco 2 AC Cooling Fan.
    If the gauge went above normal means it was too hot already cos it leaves the middle at 120*C and the electric fan kicks in at 110 by default, so if it ran full time means there was more than 110*C and that will kill the engine on a long run...

    The matrix has permannent coolant flow and the heating/cooling is managed by the servomotors which are opening/closing the flaps, when cooling is set the flaps for the heater core are supposed to be closed and all the air should go through the...

    We pre-fill some fuel filters with it neat, we've put 2-3 large bottles in with a quarter of a tank and I'm pretty sure it does very little at all but it's great that it's worked for you!

    Then read the code with nanocom or hawkeye(i dont know other tools to be 100% reliable with the Td5 engine management) but as long as the EML comes on it can be only the crank sensor or TPS unless the ECU is at fault.

    Hi, those codes seem to come from some generic scantool, anyway if it's 10P engine and automatic box the main problem is with the crank sensor or it's wiring/plug hence the EML warning and CAN fault code and the MAF fault is irrelevant unless you...
