Hi all, after some advice the temp display on my dash takes ages to go up and often starts to go up and falls back flat. It only seems to reach operating temp if I drive hard and then idle. I changed the coolant temp sensor but that hasn’t worked. any ideas? Could it be the thermostat or does this car have other sensors? I get heating like notmal thanks
thermostat tend to fail after a while as it fails to open fully. when the dash does show a lower than normal reading, changing the thermostat has more than often been the cause.
