The diesel engine thermostat is one of the important engine spare parts in construction machines and heavy-duty equipment. It can also be called a temperature control valve because it can control the valve of the coolant flow path. Generally, it is installed at the engine coolant outlet for easy maintenance.
What are the common problems with diesel engine thermostats?
There are several common problems that can occur with diesel engine thermostats. Some of the symptoms of a bad or failing thermostat include:
1.High-temperature reading and engine overheating
2.Low-temperature reading and underheated engine
3.Temperature changing erratically
4.Coolant leaks around thermostat housing or under vehicle
5.Poor engine performance
6.Engine takes a long time to warm up
7.Popping-boiling noises coming from your heater
These problems can occur when the thermostat is stuck open or closed, preventing it from regulating the flow of coolant and maintaining the engine’s temperature within its optimal range.
How do I diagnose a bad thermostat?
There are several ways to diagnose a bad thermostat. One way is to check the thermostat’s display. If it isn’t working, it could mean that the thermostat has lost power and needs new batteries. Another way to diagnose a bad thermostat is to check if your AC or heat won’t turn on.
You can also test the thermostat by removing it and placing it into a pot of boiling water. The thermostat should open quickly and completely. You can use a pair of long handle needle nose pliers to fish it out of the pot and watch it close as it cools.
If you suspect a faulty thermostat, you can run a few checks. With the engine cold, remove the radiator cap and start the engine. Look to see if the coolant is swirling/flowing immediately — that means the thermostat’s stuck open.
