Having fun on the H1 I see...
Are you getting code P1258?
I can't find anything that straight out says what an overheat condition is temp wise..
But @ 230 both fans will run on high.
The P1258 Code is an overtemp code that does not trigger till Coolant reaches 262F for 8 seconds. So you still ahve 12F to go if you're just hitting 250F. Is it going down? Or staying at 250? Are you getting any kind of warning lights? I know the H1 "parking lot" can be rough, Iwas there 2001 - 2004 I can only imagine that it's gotten worse. Sitting in traffic with the hot air from the other car's exhaust blowing over your radiator fins doesnt help much either.
If your engine DOES overheat, the PCM will turn off the fuel injectors to 2 cyldiners. This will help reduce engine tempatures.
But check, do your fan(s) come on? High? Low? Both? Does it overheat if you're in a vacant parking lot idleing?
Is your radiator hot to the touch when its been running? Fins free? Clogged?
