Does Volkswagen Bora bond heaters?

No, just apply glue to the flange seat on the outside. When installed in this way, glue can be pressed onto the inner flange base next to the engine. Some cars have a separate O-ring on the thermostat cover for sealing. Just replace it with a new O-ring, and there is no need to bond it. It turned out that the new car was not sticky when it was installed, because the new flange was not corroded and was completely flat.

Installation method of thermostat

Find the installation position of the thermostat, release the antifreeze, loosen the screws, remove the upper cover to clean up the old gasket, glue the thermostat, and increase the total sealing thickness. Pay attention to that the glue should not be too little or too much, let alone get on the middle gasket. Install the bonded thermostat on the air inlet branch pipe, and the vibration will make the glue fill the installation eaves and stick it firmly.

Screw in the screws, fill them with antifreeze and start them. Be careful to turn on the thermostat and cycle it once to check for leaks. Thermostat is a valve that controls the flow path of cooling liquid, and opens and closes the flow of air, gas or liquid through thermal expansion or contraction.

The thermostat opens in one direction. During installation, the wax storage chamber faces upwards, and the water retaining steel plate faces downwards. Usually, one end of the wax storage chamber is made larger, and the other end of the water baffle is made smaller. The water baffle placed in the thermostat housing should be able to contact the nozzle of the water baffle seat, otherwise the effect is not good.
