Diesel Thermostat Installation Kit

Product Details

dealing with frozen housing bolts

If your engine is not getting hot, the fuel will not burn efficiently - leading to more smoke and poor fuel economy. If you notice your heater not getting as hot as it use to, then this may be a good clue your thermostat is wearing out. A thermostat stuck closed can lead to engine overheating. It is not an expensive part and it is easy to install. If you have any doubts just replace it.

This is a good job to start with if you are just learning to work on your own diesel. Our kit comes with a new high quality 80 degree Celsius thermostat and two seals that will cover all applications listed above. We include PDF complete detailed instructions for ease of installation and to help keep your car safe. If you are planning to change the thermostat check the condition of the short coolant hose right below the thermostat housing. We have the kit to help you replace this hose at the same time you do the thermostat. Look below.
