When dad drove ute he diddn't seem to have any probs but when i drove it with the headlights on it pushed temp gauge to the red zone (80kph 30deg day). Seems the problem is when a roobar is fitted to the tritons they need to shift a earth point because of the roo bar, so got the earth point reconnected in a different spot and hey presto no more problems. The mitsi mechanic new his shit
I just did a search and found similar threads about this electrical gremlin. I wonder if there is a bad earth causing the engine's electrics to send wrong info to injectors, sensors etc. ? I seriously considered this possibility on the weekend as while highway cruising, the car had no grunt up hills. Where I'd normally pull top gear doing 110km/h, it dropped to 4th and revved out doing only 95. Another factor is the noise. It sounds like the motor is pinging like a petrol with the ignition timing out. Something isn't right and it ain't just the cooling system.
Speaking of which, it began leaking again, hot and cold. Going up the Hume Highway on a 41 degree afternoon, doing 100 up hills, it got to 104 degrees. As soon as I backed off on the throttle, it cooled back to 90 quite quickly. Only under load will it get hot. I got some liquid metal epoxy into the suspect radiator channel and used multigrips to squeeze the plastic tank's metal "fingers" a bit tighter in case they'd been stretched out due to extreme pressure. So far no issues since the repair.
Now, to find a bad earth....
