I have 582 that on initial startup runs up to 180 degrees and then drops back to 140 and stays there. Are there other thermostats available? Say, 160 or 180’s. Would be nice in this cold weather!

Hi Frank,
I have a 582 in my model 3 with a 130 degree thermostat. When it is warming up I'll see the temp gauge go up to about 140 and then back to 130. I'm assuming this is when the thermostat is opening. Once this happens I simply go fly. I once tested the 'shock cooling' by descending 6,000 feet (over a frozen lake for safety) at idle. The temp never went below 130 and upon opening to full throttle there was no hesitation.
As an aside my Skystar supplied cockpit heater keeps the interior about 30 degrees warmer than ambient temp. When it is below zero frost builds up on the windscreen, so I generally don't fly at temps that low. Perhaps a hotter thermostat would provide more cockpit heat.
Regards,
John Stoner

Thanks John for your input. There was no pretense at making the Kitfox air tight and we all know that they leak like a sieve so any additional heat is appreciated. I also have the small heater that I assume came from Kitfox and it helps keep my feet warm.

I seem to remember reading somewhere that these two cycle engines should run at 160 and not exceed 180 degrees but I may remember wrong. I do that sometimes. If there is a different thermostats for them I have not been find it. Thanks again.

Frank

Are all these very stable temps with a model 90 or a Bluehead mod 99??

Standard thermostat will open about 135F- 140F so you will see you gauge go to 140 or so then once it opens it will drop back to 130f or so as the cold coolant from rad starts to flow then the thermostat will close again till 140F again. This cycle might happen a a few times until the engine can finally keep all the coolant over 140F, this is what I wait for until full power is applied.
When flying and after a long decent with temps in the 130 or lower range, I would be use less throttle until the engine temps get up to 140F or so again, full throttle could bring on a "cold seizure" at this point.

Simplest solution is to cover up part of your Rad or design a shutter for it . Normal operating temps should be 160 to 180F, over 1860 F is the caution area and 200F is definitely a trouble zone. If you thermostat is opening at 180F could it be sticking or a off brand that is doing this ? Sounds like it works ok though ?

The Blue head has the by pass on the engine and helps it keep warmer by being able to circulate the water around the engine in a loop before the thermostat opens. My Blue head is at 370 hours or so since June 2006 and never been open yet. It could fly apart at anytime now , that is my disclaimer Smile

- To help with the rad temps, I use "Thermostat 3853799 Bombardier Evinrude Johnson", in the fall and replace with the Rotax one in the spring. This thermostat is 160F and I see temps of 160 - 170 regardless of what I do with the throttle.

- Ensure the water temp is warm, I use about 130 before I rev over 3000. Ensure that the thermostat is open and water circulating for a few minutes before high power operations.

- I preheat the engine at all winter temps with an inline radiator heater. I got mine for $20. specifically for Ski Doo. ( any 1" hose one will do). I set it on a timer the night before I fly. Amazing what a difference an hour or 2 of heat will do. Starting water temp 80-100F. It starts and idles better at 20F after heating than in the summer. ( tells me I must have the summer idle too rich?)
