In this video, I will show the explanation of how to remove the coolant and diesel filter, and also the place for engine pre-heater installation, in particular, on the Toyota RAV4 D-4D diesel engine.
Then you need to find the place for heater installation. Locate two hoses that go into the car heater and check the left one (to the heater) is connected to the turbocharger and the right one (from the heater) is connected to EGR. You will need to install the heater as low as possible into the left hose.
Toyota D-4D diesel engines are quite reliable and can be used for hundreds of thousands of kilometres. However, living in a cold environment the life of the engine can be shortened by cold weather and short trips. Even though it is not a problem to crank the engine down below -20C, it still helps to have a heater. I have been considering a few options such that Webasto and 220v electric coolant heater. The last works much better for me due to the fact that I have access to the power outlet and it takes only a few hours to install without considerable modification of the car. Depending on the engine specification, you can install it right before the pump between the engine and lower radiator hose. However, 1CD-FTV has thermostat right where the radiator hose connects to the engine, so it does not make sense to install it there. As a result, I chose to put it in the hose between the engine and car cabin heater that is located right beyond the turbine under diesel fuel and air filter. The manufacturer recommends using the heater for no more than 3 hours. Also, make sure that you drive the car for some time to exclude the air from the system.
