VR Running hot

[dannad]

Hey just a question my VR if setting idaling for not too long 10 mins or so heats right up until the fan decides too work about half temp (not nice sitting watching temp guage going up) what could be the issue?

It could be the thermostat not opening when it should or a faulty temperature sensor.

does the temperature go down when the fans kick in? if so, it sounds like normal operation to me.

While driving, the temp' will normally drop as there's air passing through your radiator. When at idle, there's no air passing, therefore the temp' will climb until the fans kick in.

My first car didn't have a temperature gauge (LH Torana), I had no idea what the temp' was. I think these extra gauges are more trouble than good.

Get into the habit of checking your coolant level, and unless you see a leak or your engine smells hot, I wouldn't worry

Wouldn't stress to much, as long as it drop when the fan kicks in.

If it doesn't, check thermo and look for any leaks.

Mine goes up to 3/4 in heavy traffic, I have flushed out the cooling system, new thermostat, changed the temp sender & temp sensor for the ecu, checked the temp sender wirring, bled any air out of the system, the water pump is good & radiator is good, there is no coolant leaks, relays are working properly as well, all of this made no differance to the temp guage, apparantly its normal for them to go either 1/2 or 3/4 on the temp guage before the low fan cuts in, it used to worry me but now if I am stuck in traffic I just switch the air/con button on and it never goes past 1/2 way in heavy traffic.

sounds normal, your car will generally heat up more idling then driving as there is no cool air blowing onto the motor/radiator. the eletronic fan acts like cool air blowing on the radiator whilst driving. you only really need to worry if it creeps above 3/4.
