Took the 5.0 to the snowy mountains over the last week and she devolped a nasty overheating issue. on the long drives up and around the park the needle slowly nudged its way towards the orange section. Also there was a distinct smell of fuel in the car. there was only 95 octane fuel available, on a 16deg day, not fully loaded, the auto was just fine. Also a noticable drop in power. These hills were fairly steep and the car was driven between 60 and 80 for periods of 6 to 10k's all uphill. On the downhill runs the temp returned to normal.MODs as listed. Unichip, 4in cold air intake, k+n filter, lukey extractors, 2 1/2 in single from the cats back. Help much needed

I'd start by checking the timing. Is the dizzy tight, it may have possibly moved.
Also, it might be worth checking the thermostat is operating correctly.

Could be many things, radiator could be blocked etc. As for noticing the power drop, unless you live around there, you will notice a big drop in power, higher you go the less air there is, you would have noticed the power was back to normal when closer to sea level, same thing happens around New England area. (Armidale, Guru etc is around 1000m above sea level) BTW until the ECU can work out what the hell is going on up in the mountains, the engine will be running much richer than normal.

Timing is spot on, dizzy has not moved, radiator is fresh( less than 20k old, same as thermostat and this is my 3rd water pump in 40k. when returned to sea level, power was as normal, and temp didnt change all the way back to sydney from canberra onwards. Will keep looking and any other ideas might be nice. As a side note returned 12.5l/100k for a total of 1900k's in the week. This is the first trip since the mods were performed and am mighty impressed( used to be 16-17 per 100k's combined city and highway) Also have noticed in the last 2 days a leaky exhaust from the left hand back, but in to the shop for that today

3rd water pump in 40k?? sounds a bit strange, was the radiator new? what was wrong with the water pumps when you pulled them off? maybe coincidental, but maybe not. How long is it since the radiator went in? has the coolant been changed every 2 yrs?

it has been 40000k and 18 months for the water pumps. Both the replaced ones had blown seals on the top of the pump and could empty the radiator in less than 10 mins. The radiator was replaced with a genuine 5.0 aircon unit from ford about 20000k ago. first water pump was blown when car brought, 2nd was replaced under warranty, third is still in car showing now complaints as yet. Coolant was replaced on each replacement of water pump. Have had the car 2 yrs as of march this year

Your overheating may be purely due to the high load placed on the engine for an extended period. The factory radiator isn't the best, but being new I still wouldn't really expect overheating. When the engine coolant temp gets hot, the computer pulls a lot of timing out and runs the engine fairly rich to avoid any damage, that is why you felt a power loss.
Although unlikely the cause of the overheating but maybe contributed to loss of power, the computer senses high altitudes and changes fuel maps, maybe the unichip wasn't mapped correctly for high altitude. |
