I have a Renault RT S reg hatch the gauge goes into the red but the overheat light never comes on and it appears not to be over heating, possible causes of this please.
sorry forgot to say if cheaper option fails if the gauge goes straight to red when ignition is turned on then it is prob the gauge its self these are not as cheap as the early option before you buy one make sure you trace the wires to make sure that the wires are not damaged causing a short , hope its the first option .
