How to Install an Engine Heater

Installing a Tank-Type Heater

1). Drain the radiator.
2). Cut one of the heater hoses at a location where there is room to mount the heater.
3). Slide a hose clamp on each end of the hose and push the heater hose onto the nipples of the tank heater. Slide the hose clamp in place and tighten securely with a screwdriver.
4). Refill the radiator with a 50-50 mix of antifreeze and water.
5). Plug the heater in to turn it on.

1). Drain the radiator.
2). Cut the lower radiator hose a few inches below the engine water pump. These heaters work best on a vertical section of radiator hose close to the water pump.
3). Place a hose clamp over the upper end of the radiator hose. Slide the heater into the hose and position and tighten the clamp to secure the hose to the heater.
Secure the lower section of hose to the heater with another hose clamp.
4). Refill the radiator with a 50-50 mix of antifreeze and water.
5). Plug the heater in to turn it on.

1). Drain the radiator.
2). Locate a freeze plug with enough room around it to give you room to remove it. Removing the freeze plug is easiest with a punch and hammer. Try to punch one side in to the engine far enough to insert a screwdriver in and pry the freeze plug out.
3). Coat the gasket on the freeze plug heater with a little RTV sealant and insert the heater in the hole.
4). Turn the screw on the heater to tighten it into the freeze plug hole.
5). Refill the radiator with a 50-50 mix of antifreeze and water.
