After driving through town, the water temperature gauge on my Sportrak started to rise. Within 1 min, it was at the top of the gauge.
I pulled into a garage to check the water, and it was low. I let it cool down and then put warm water in.
Drove 12 miles and the gauge started to go up again, it then fluctuated from nearly at the top to half way.
After staying normal for 5 miles or so, it suddenly went to the top again.
I pulled into garage again to check water and it was low again.
Refilled after leaving to cool again.
Water was a rusty brown colour.
Drove another 15 miles and it was fine, never moved from half way.
I noticed that after I refilled it the first time, the fan belt was slipping and screeching, also when driving along at times.
Also, radiator cap wasn't letting excess water in to expansion tank.
I can't see any water leaking anywhere, and the oil looks ok.
Can anyone give me any advice as to what to look for, as I've only had it a week, and its my first 4x4.
