Due to the cooler temperatures here in the NW my oil temps stay mostly on the cool side and it take a pretty long warm up period to reach the min. temp..



I decided to buy and Oil thermostat from CPS ( see attached pic  )



I am curious if anybody is using this thermostat and if so, how & where did you mount it ??



Some pictures would greatly help.



Thanks in advance

Hi Bernhard,    (there was no name  on your post?)   We are in the NE and run our Allegro in the cold  temps. Last fall we had our mechanic install the thermostst you bought, on our  912s. We got it from Lockwood. I flew the plane alot (demos and shows) and can  tell you it made a hugh difference.  Oil temps came up to operating range  in 5 min. not 15. In flight temps run 182* - 184*. Right where you want to be to  displace moisture. I was not there when the mech did the installation but I know  we needed more oil line. The owner may have taken photos, I'm not sure? He may  be able to help you out more as he was there when it was installed. His name is  Lee Ramsdell. You can contact him at landlsportaviation.com  I also read  something recently about trying not to use 90* elbows which may restrict flow.  You may want to check with Rotax in regards to that?                                      Bob  Griffin    Berne NY

Bernhard10,



I bought the identical oil thermostat from Summit Racing and installed 

it over a year ago. Next time I'm at the hangar and have the lower 

cowling off, I'll take some photos of my installation. It was a tight 

fit but it works pretty well.



It speeds up the warmup period and helps keep the oil temperature up 

closer to normal in low power situations. Keep in mind it is always 

open at least part of the way(10% or so) even in cold weather so that 

there is some oil flowing through the oil cooler at all times. It 

should be wide open by the time it reaches 180F so above that 

temperature it will just as if there was no thermostat installed. Below 

180F it gradually closes down to keep the oil from getting much cooler 

than that. On ours, at very low power settings the oil temperature runs 

around 170F now, much lower before the installation.



I'll give you some pointers when I get and post the photos of how we 

did it.

Thank you so much for your input.  and yes I look forward to the pictures so I can get the installation going. I want to combine it with my oil change which is pretty much due.

I also read somewhere to avoid 90 degree elbows, that's why I ordered the straight fittings and hope they will do the job.

Looking forward to learn some more and see some installation pics, fly safe

Bernhard
