Hi there,
Own a 2000 Renault Master 2.8dTi. Have been trying now for a few weeks to work out why the Coolant Temperature Warning Light comes on after I start driving. The temperature gauge rises to a 1/4 - doesn't sit in the middle and for a while everything is fine and no light comes on. After around 10 minutes of driving the Coolant Temperature Warning Light comes on and stays lit red for the duration of the journey. I have stopped stopping to check if the engine is overheating (doesn't seem to be).
So far I have drained the coolant, checked to see if the thermostat is working fine (put in boiling water - seemed to open okay), replaced the temperature sensor, re-filled coolant with bleed screw open to avoid air bubbles etc.
Does seem to be a fair bit of oil all over the connectors and thermostat housing.
What could be causing the light to come on?
Thanks
Ben
