Using the Rear Heater Sideways

[cofrari]

I was hoping to continue to use the rear heater, but I would like to place it sideways built into a partition wall. Basically the fans would blow from about the left wheel well backwards (versus upwards). Would running the heater on it's side cause any issues, like leaking coolant or anything like that?

shouldnt cause the coolant to leak but for the fans to blow air they need to be able to draw air in so you need for airflow on the air in and out or you will burn the fans up and get poor performance out of the heaters ability.
since it has fans then you could add some ductwork to get the return and supply air into a clear spots but depending on your space plans that could eat up some more storage or whatever space

The bearings in the squirrel cages might not take the side load, especially if they are ball bearing. Not designed for side load, hence the weight of the squirrel cage.

Would work, but how long?
