  Q: What are the steps involved in the removal and installation process of a thermostat on Mitsubishi Diamante?

  A:

  The first step in the process of removing and installing is to first disconnect the negative battery cable and drain the cooling system, and in order to be safe, it is essential not to service or drain the radiator or cooling system when hot since this may result in burns due to steam and hot coolant. Use care with ethylene glycol antifreeze that is lethal to pets when ingested and never empty coolant into a container unless it is sealed to be used again unless contaminated or more than several years old. The second step is to take out any parts required to reach the thermostat, and then take out the thermostat housing that has the bolts and pull the housing off the engine. Cautiously take out the thermostat taking note of the position in which it was initially placed in its housing. To install, both mating surfaces must be clean and without any old gasket material so as to avoid leakage. Install the thermostat by fitting its flange into the machined groove, and aligning the relief valve with the mark on the housing. Install a new gasket or O-ring to re-fit the thermostat housing, and tighten the mounting bolts to the required values of various engine types. Once that is done, add coolant to the system, reconnect the air intake plumbing, reconnect the negative battery cable and drive the vehicle until the thermostat opens and the radiator gets full of coolant. Lastly, after the vehicle is cool, recheck on the level of the coolant.
