my engine overheat, please help

I am traveling with a van. The engine overheat, especially when climbing slope. If driven on a flat road, it looks OK.
I already added coolant, actually there is no coolant leakage.
I need to drive another 400 miles to home. I might not be able to have it fixed locally since tomorrow is Christmas holiday, shop is usually closed.
Any suggestions that how I can drive safely to home without engine broken?

• 与机油和 transmission fluid无关。注意一下radiator风扇是否工作。 -毅然- ♂ (0 bytes) () 12/24/2012 postreply 06:08:11

• 很可能 thermostat 坏了，它不能完全打开，所以平路尚可。 -旅顺口- ♀ (0 bytes) () 12/24/2012 postreply 10:55:25
