Coach engine heat

[Jon Kabbe]

I have a 1977 coach that doesn't seem to have the boost pump or the switch, so I suspect that it didn't come equipped with the pump. Are my suspicions accurate? The heater doesn't keep up with the cold despite all the values being in the right position. I get heat, just not enough. How much work would it be to add the pump?

The addition of a coolant pump as standard equipment for off-engine
heaters began in the 1980s. Installation of a 12-volt booster pump is
fairly straight forward. There are a number of possible locations, but
ease of access, availability of 12-volt power, and a forward location,
should be prime considerations. Contact our parts department toll free at 1-888-363-9355 to order the parts you need. You may also need to consult with the Newell Service Department regarding the pump model they recommend.

I talked with Gary in Parts and he said he no longer stocked the pumps. I found the following web site that has them available: http://commerce1.cera.net/tacbusparts/sections/catalog/catalog.asp?cat_id=155 A
