Hi Everyone,
This is the first time I've asked questions in a forum, hopefully I've done it right.
I have a overheating problem I hope someone can help me with. I have a Toyota Prado, Diesel, Auto, Year 2000.
The temperature rises dramaticaly on a long incline when the vehicle drops down a gear, this happens on the freeways. If I just slowly drive, without it kicking down, going about 60klm an hour it doesn't over heat, but if I put my foot down the temperature goes into the red. It doesn't overheat in normal driving or bumper to bumber traffic on hot days, only seems to be on long incline on freeways eg. (NSW) the m1 at Ourembah (heading south), the Hawksbury (heading south) and the high country (Hume hwy Victoria). No extra weight in the car and not towing anything.
I replaced the Radiator (new) and thermostat, apparently the water pump is OK and had the head replaced (wasn't replaced because of the overheating problem).
I've tried searching for answers, the only other thing I have come across is the "viscous fan hub", but I'm thinking this would cause overheating problems in more occasions than just the ones I'm having.
