Ford Explorer Thermostat Housing
Diagnosing Malfunctioning Ford Explorer Thermostat Housing
As tough as the Ford Explorer's thermostat housing can be, it is still prone to breaking down like every other part. Unlike every other part, it's far more difficult to tell when your SUV's thermostat housing starts to fail and falter. That said there are certain signs that you can look out for that will allow you to place the housing on a check list of parts that might be causing the trouble. Here are a few of them-ordered from the most specific to the most general:
Loud clanking noise under the hood
On the rare occasion that your Ford Explorer's thermostat housing breaks apart completely, the first thing you will hear is the loud clanging noise as the heavy steel housing bumps into the parts next to it-even the body of your SUV! Naturally, sounds under the hood will be difficult to isolate. Even if we did mention that the sound will come from the front-most part of your SUV's nose section, it will be difficult to tell when it happens. Hopefully, when the loud noise jars your driving, you can stop, and inspect under hood. Luckily, the broken thermostat housing is the first thing you will likely see the minute you pop the hood.
Frequent engine overheats
Since the thermostat regulates coolant flow to the engine and back to the radiator, one of the symptoms that the thermostat housing might be damaged is when you notice that the SUV heats so often. It's a clue, but not a sure thing, because technically, the assumption is that if the housing is damaged, the thermostat is too. That might not always be the case-in some instances, even with the housing damaged, the thermostat "soldiers on" as it were and keeps on working.
Engine shut down
This last one is included in the diagnosis checklist but is in fact, not only the least reliable, but the one you aren't likely to encounter. If an engine failure is indeed caused by the failure of the thermostat housing leading to damage to the thermostat, then you weren't too conscious of your SUV's functioning as you should have been. By this point, you see, even if you do find fault in the thermostat housing, the engine itself-not to mention the radiator-might need replacing already as well.
