Hi there, and thanks for the inpass on this forum. Much applied! :-)

My son recently bought himself a 550 Zforce EX 2021 with closed cabin and heater.
Though i cant say im very impressed with the heat that comes out of it. Ive tried to seal up open gaps here and there. But even when the machine is on idle it only reaches 3 out of 8 dots on the engine heat. Ive tried to block half the radiator and such but no luck. Im starting to think the thermostat doesnt work proper? Ive had a Polaris Ranger back in the days, and it was like REALLY hot inside heh.. Hope someone has some good tips for me to try out. Because when it hits around -10C its nice to have it working.. :-D

From Norway with love!
Cheers.

Three bars is the normal operating temperature for all CFMs and when it's cold like it is there, for a 500/550 engine to put out enough heat to cause the cooling system to exceed that is going to be next to impossible. You would have to cover 90% of the radiator and run the heck out of it to make it run hotter. I would look to sealing-up all the open cold air sources like all across the front clip and firewall plastics, tunnel opening up front, and all the other holes around the cab. Then explore other heat sources independent of the engine cooling system. I know a guy that built a box to go around the exhaust pipe and had ports on either end-one to blow air in and one to blow hot air out through a flex duct into the cab. Worked great along with his other heater. Said he got the idea from a Volkswagen Bug's heat system.

Aha! Wow thats some good news atleast. Then everything is quite normal i guess. I will continue seal around in nooks and crannies and try to eliminate as much cold air as possible. I think it will do just fine. Thanks alot for quick reply. Much applied! :-)
