Starting the engine in frosty winter conditions is very difficult. In addition, the engine is subject to increased wear due to the high viscosity of the engine oil (antifreeze), which is observed at low temperatures. An oil preheater will help to reduce engine wear when starting and greatly facilitate this process.
Instructions
Step 1
Take a heating element from an electric vulcanizer powered by 12 volts. The choice of a heating element of this type will allow the future heater to be powered from a car battery and to heat the antifreeze before starting under any storage conditions of the car. In addition, this option will not significantly discharge the battery before starting, but on the contrary, it will allow you to warm up the battery. After that, she will turn the starter better.
Step 2
Select a suitable cylinder for the heater body. It is important that this part consists of two parts, connected with screws or other types of fastening. This will provide convenience in the manufacture of the heater and its repair. Provide a sealing gasket for the attachment points of the housing parts.
Step 3
Place the heating element inside the housing between two layers of asbestos. The element must be installed tightly, without gaps with the asbestos layer, and not come into contact with the heater body.
Step 4
To install the heater, it is necessary to make two stands. They will also carry the function of contacts, i.e. supply voltage to the heater.
Step 5
From the engine crankcase, partially remove in two places the cooling fins on the lower surface of the crankcase. Then drill two holes for the heater contacts.
Step 6
Install the heater so that it is located 8-10 mm above the bottom of the crankcase. Additional convenience in installing the heater will bring hatches, if they are installed on the crankcase. There are such, for example, on "Moskvich-412".
Step 7
Electrical isolation of the contacts-racks from the heater body and from the bottom of the crankcase using bushings and washers. The material of manufacture of these elements must provide thermal and electrical insulation. The best material will be fluoroplastic. Please note that their installation should prevent oil from penetrating into the heater housing and from its leakage from the crankcase.
Step 8
Connect the heater installed in this way to the electrical system of the vehicle through a rectifier.
