| The coolant liquid is circulated by an electric pump, through the motor and though a small radiator. Together with the heater circuit (which runs independently and has its own circulation pump), the cooling circuit is connected to the original coolant liquid reservoir. The air buffer in the reservoir will take up thermal expansion of the coolant liquid, and it can be pressurized to ease refilling and emptying of the two circuits. | The coolant liquid is circulated by an electric pump, through the motor and though a small radiator.

| + | Coolant terminals on the motor. Please note that the fittings used in below foto turned out not to be tight - I have replaced them later. The new fittings have a flange to press a rubber gasket against the motor's case. | ||

| + | The coolant pump (again a Volkswagen Vanagon Turbo Diesel circulation pump, as for the heater circuit). This recent model by the way has a brushless motor with magnetic coupling to the pump chamber. It runs on very low current and appears quite long-lasting. | ||

| + | As usual, every component has its own flange diameter, and I needed to solder a couple of adapters. To start with, it is always good to have a plan of the puzzle: | ||

| + | The first picture shows two mistaken ones, corrected in the second picture. Note the additional small diameter pipe on one of the adapters. It connects the cooling circuit to the coolant reservoir via a thin hose. | ||
