582 Aquila running hot

[Heever]

Ons het n 582 AQUILA, en vind dat hy warm word. Soms tot 85 grade, ek wil graag raad vra, wanneer moet ons bekommerd raak? Na wat moet ons kyk, plugs is vervang,airfilter al skoon gemaak! Sal graag julle advies wil hoor want eks maar nog n groentjie

Watter coolant en olie gebruik julle?

[Heever]

Caltex anti freeze met low silicon and caltex two stroke

make sure you are running a 50/50 mix in the coolant. Also if you fly with a really big passenger it will run warm.

we fly this evening with a tiny girl and it also getting warm??? any advise????

[Africa]

haha ok, all I can think of is your coolant mix then. I would also hook up another temp gauge as those solo wings use are not the most reliable

[Heever]

maybe thats the girl behind me who makes me hot ha ha ha

hahahaha maybe, that and you problay live in hoedspruit or mesina where the temps have been 40 degrees

I also have 582 on my trike that runs a bit hot sometimes (I normally land when it goes over 80). Here are some of the lessons I have learned:
- I can fly safely up to a certain air temperature without overheating (about 30-33 degrees for my trike)
- As mentioned the antifreeze mixture is very important. The more water, the better the cooling and it makes a big difference! What I do is to fly with a 50/50 mixture in winter but with a 30/70 mixture in summer. Do not go below 25% antifreeze unless it is an emergency and you have to get home on a hot day! (No comments about what the book says please, I know it say keep it above 40%. ) Above about 70% antifreeze starts making a boundary layer and it will inhibit cooling - more or less a recipe for disaster.
- I can not fly with a passenger on a hot day without overheating ( about 27 degrees)
- If I obstruct the airflow behind me, e.g. extra fuel tank, if does influence the temperature
- I have flushed the engine (no sediment or anything found) and I have record the radiator and it did not make any difference.
- I have added scoops to the sides of the radiator and it did make a slight difference, maybe 3-4 degrees
- I do not know if my observation is correct but I have a feeling that if the air is dry it is worse. (I live at the sea)

I bought the trike with the radiator and my radiator is not a Rotax radiator but one that was bought from one of the trike suppliers I understand. I have asked other people and nobody that I know of overheats if they have a Rotax radiator (the 2 small vertical ones) installed. The area of my radiator and the Rotax one is about the same so I have to assume that the Rotax is more efficient.

If your trike used to run cool and overheats only recently I will be worried, check you thermostat and water pump. If it has always been like this you can probably fix it with either the mixture, repositioning your radiator or fitting a new radiator. Note that if you make a custom radiator the automotive guys design a radiator to run at about 100 degrees and we have to run at less than 80 - a big difference.

Petrol filter??

My enjin het ook warm geword (90grade) veral in die middag na 'n warm dag,ek het my antifreeze minder gemaak 30/70 en my probleem was opgelos ,hy word nog warm as ek met 'n swaar passasier vlieg in die middag veral as die enjin vir 'n lang ruk op 6000 revs loop om hoogte te kry en tydens touch en go's ,maar sodra ek straight en level vlieg met die revs op 5400 kom die temp af tot by 80 .Ek het my AP gevra wanneer ek moet begin bekommerd raak oor temp en hy't gesê eers vanaf 115 grade raak dit kritiek.

Kry vir jou 'n ander AP. 15 Grade bokant kookpunt ...??? smokun...
Die tipe temp,....... is dalk fine op 'n 912.....

Jy trust hom ook nie ....... dis hoekom jy vra..........?

Ek is heeltemal bisexual sorry bilingual(tweetalig)l, if you can please post in english so that the other plebs and overseas people can understand?

Just a request,
