I have a Grey Head 582 running at climb 5800 rpm 180 degrees at cruse 5400 rpm 170-175 I  and 70mph I have Changed the pitch from static 5800 to 6200 and no change I have a two blade IVO Medium for at least 100 hr now  Checked the carbon on pistons but looks clean  I moved the radiator down one inch to get more air on it , the outside air temp is been 80-85 water is a 50-50 mix it is two years old and 183 hrs, egt's run about 1150-1100  no cht gage,  it cools right off when pulling the throttle back and slowing down, at 6000 rpm level still runs 180 + but i don't go much hotter.  Question; How hot do people run there's , What can I look for to run cooler ? My next place will take out temp sender unit  and put in hot water with thermometer to see if the same. ANY thing will be appreciated,  Thanks

Hi

  

 Do you have a radiator scoop?

 calibrated RPM indicator?

 Jerry,

     I run up to 180 on takeoff if the ground is above 90F. S&L I rarely go over 160 no matter how hot it gets. I'd check the thermostat- I've had several fail, sometimes they even break in half. Check the vent in the water pump to make sure you don't have an air bubble. Make sure none of your water lines loop over such that they can trap a bubble.

....water is a 50-50 mix it is two years old and 183 hrs............



In the winter you need more anti freeze but in non freezing month or location you can run 90% distilled water and 10% dexcool . Your temps will drop. 



I would also swap temp and /or sensor , one at a time to make sure they are correct. 



My Kitfox has run without a problem  at 180 F cruise indicated for over 1300 hours on several engines. 



You would make your prop a but finer as well likely if you using a tiny  tack.  those Rotax tachs are rarely accurate.   2 blade medium static 6300 to 6600 -- once airbourne they coursen up a bit.  Great prop but you gotta tweak it like any prop. 

Hope that helps

I had a Mk 4 582 before my Mk 5 and when I bought it the engine (grey head) coolant ran quite warm.  Your EGT's seem fine if they max at 1150 and I wouldn't be too concerned at those.  Contrary to what many people believe, these will rise with cooler ambient air so in the Summer you will find they are fine but might creep up to 1200 in the Winter.  Coarsening of the prop SHOULD help this and I used to adjust my prop to the EGT's as the seasons changed and it worked a treat for me.  I aimed for 6200 static.



Regarding the coolant temps, I did the following (and in this order):



1.  I reduced the coolant percentage to 75 water/25 coolant which made a bit of difference (about 10 degrees).

2.  I lowered the radiator and this did nothing.

3.  I moved the radiator back 2 inches and this did nothing.

4.  I then decided to buy the over-sized rad from Kitfox and the temps dropped by 30 degrees and ran comfortably at 160 from there on.



I know it is an expensive option but it worked really well and I could return the coolant back to the 50:50 ratio with no worries.

Depending on where you live, you can dilute your coolant to about 75/25. Ethylene Glycol is an insulator, not a conductor. It is a double edge sword, however. The lower ratio will boil sooner, but it cools better.



In a 2-stroke engine, the mixture cools the cylinders as well. if you're running lean, it will run hotter. Richen it up a bit to cool it down. Also check your oil flow; it may be a reduction in flow. Of course if your pre-mixing, you can add a little bit more to the mix. otherwise, check your oiler to make sure its working properly.
