At least you did your research, best to do that than to find out you got a lemonYeah when searching around about these I saw quite a few people on Polaris forums that were having problems with them. The trouble I go through to keep the wife warm and happy...............
I agree with everything you say. The design lacks enough coolant flow to heat.Got the Firestorm heater all hooked up from Motoalliance this weekend. So far not very happy with it. After going through the instructions over and over im almost wondering if they have ever put one on a Viking. Seems like im the first one that is doing it. Instructions weren't very good. The heat that mine puts out is less than impressive. Barely warm. when driving and cold at idle. Ill have to get a hold of them and try to troubleshoot this thing. In the instructions they talk about the upper radiator hose and the lower radiator hose. On the Viking both hoses are right in the middle of the tanks of the radiator so really there is no upper or lower. Grrrrrrr!!!!!
Yes, the kit comes with two Y fittings that you have to cut both radiator hoses and put the Y inline. Then on the remaining nipple of the fitting is where you put the heater hose that goes to the heater core.So what I'm hearing is that you don't interrupt the flow to the radiator, which would divert the water through the heater core...then to the radiator? What you seem to be saying is that you tap into the water line and then some of the water flows into the heater core, while some still flows into the radiator? I did read somewhere that getting all of the air out of the system was critical. I saw that some Folks were jacking the front of the machine way up and then cracking the radiator cap. That way all of the air bubbles went to the highest point.
I'm pretty sure these have a thermostat, so you should be able to tell which line is which by starting the engine and then feeling both water lines. One should get noticeably hot before the other.
