问:过热

我父亲和我取代上周末我汽车上的恒温器。这是星期六。我们都检查我的车后,运行热几时间。,来到最便宜的结论。更换温控器。低,当我们把住房的恒温器垫片磨损。关闭关闭。我们都很兴奋,我们猜对了。我们取代了一部分,跑好了25 mun加热。第二天我精心去上班,它开始运行热大约5英里的房子。 Later that evening we relived some of the air pressure from the water pump reserve to see if that was the culprit. But it didn't help much. I have no leaks under the car and no cloudy oil that would indicate a blown gasket or cracked head. Please, what do you think the prob could be?

我的车有227000英里。
