Remote oil thermostat

[jrthomas]

Are most of you running the oil thermostat? I can't seem to find any information on purging the system with the thermostat. It seems to me that the thermostat redirects the flow through the oil cooler when the temp reaches a certain level and by purging a cold engine, the oil cooler is being bypassed. I had a small leak on one of my oil cooler fittings and may have allowed some air in. I need to purge but I want to make sure I do it right. Thanks, James Thomas

All of the new SLSA use oil thermostats, mine didn't come with one, but John has said I could add one when I do the 5 year hose replacement. I'd need to go read the instructions to better understand how they work. They mount them behind the engine on the lower engine mount tubes. I do have some photos of the installation if interested, and I also have the installation instructions. I could make a PDF of the installation instructions as well.

Kitfox sells an oil thermostat kit with all the hoses and fittings you need, as well as instructions.

I purged my oil system just the way Rotax says to do it and had no trouble because of the oil thermostat. I believe the thermostat never totally blocks off the oil cooler, so when you purge you will move some oil thru the cooler.

My experience is the same a Jim's, I have a thermostat and use the normal purge procedure.

I suspected, based on the lack of any info otherwise, that the purging process would be the same. The oil thermostat I have is the same one that Spruce sells, (#15-05849). Their info says it remains 10% open so, hopefully, purging will displace any air that I might have let into the oil cooler. Thanks again, James Thomas

crank the engine with the mags off. if you have oil pressure you are purged. you can also do the prop turning until it gurgles in the tank. the oil thermostat works by bypassing the cooler, same thing as going through the cooler. when it gets hot it allows passage through the cooler. not an issue for purging air at all. the air doesn't know the thermostat is there.
