I could put something like the one in section 4 here http://www.rotaxservice.com/rotax_engines/rotax_914UL.htm But I found one I like better, if just for the fact it is advertised for both Rotax and Jabiru engines. It is sold in Australia by mcoates@xair.com.au . They claim it is made in USA so I wonder where I can buy one over here. I d like to hear your comments and suggestions. Here is how they say it works. > > I have just come across one of these products and it's a specially designed thermostat system designed to regulate the oil temperature on engines like the Rotax and Jabiru. > > We are all aware of the damage which can be caused by running your aircraft engine oil temperature too low, in fact it has always been recommended to get the oil temperature just over 100C during each flight to burn off the water which can contaminate the engine oil, if you are flying time and time again and the engine temperature is only getting to say 85C the water will remain in your oil as a contaminant and can go on to destroy your engine with corrosion problems. Additionally, warmup is achieved very quickly on even the coldest of days because the thermostat diverts the oil flow from the oil cooler. > > Made in the USA these special oil thermostat units are designed to quickly allow your engine to reach and maintain its optimum operating temperature even on the coldest of days. > > CNC machined from 6061-T6 the unit is anodised with the type 2 surface finish to protect the thermostat long-term against corrosion. All of the hardware is aircraft grade and the oil thermostat unit is finished to the highest possible standards and is supplied with hose nipples to fit the most common oil tubing diameter used by Rotax and Jabiru. > > There are a number of benefits in using an oil thermostat in your aircraft which include fuel savings resulting from quick warmup times and engine operation at optimum oil temperature which also increases engine life because the engine is being operated at the correct oil temperature. > > > **************** > > I have been asked the same questions by most of the people I have shown this thermostat unit to... > > Will it reduce my oil pressure? The simple answer is no installing an oil temperature thermostat may slightly increase your oil pressure when it is most needed during cold starts. It offers a shorter, less restrictive flow path to the lubricating oil while the engine is cold. The cold oil bypasses the oil cooler and eliminating the small pressure drop that would otherwise occur. > > Can it block the flow of oil? No, it cannot block the flow of oil in any circumstances whether operating normally or in a failed condition, it is impossible for the unit to block the flow of oil or the oil circuit. > > What is the warranty period? The warranty period of the oil thermostat is two years. > > How big is the unit? The unit is really small being 55mm high, 55mm long (without the hose barbs) and just 40mm deep, the unit can be bolted to the firewall or a bracket with the two 3/16" mounting holes. > > Most important... The Cost? The cost of the oil thermostat with oil hose nipples is only $200 AU$ plug GST and delivery. > > Read this topic online here: http://forums.matronics.com/viewtopic.php?p=285987#285987 Attachments: http://forums.matronics.com//files/pic1_small_213.jpg http://forums.matronics.com//files/stage_1_112.jpg http://forums.matronics.com//files/stage_2_197.jpg http://forums.matronics.com//files/stage_3_485.jpg ________________________________ Message 3 _____________________________________ Time: 11:50:28 AM PST US Subject: Lightning-List: Re: Oil Thermostat From: "Bill Strahan" That looks pretty neat. On a particularly cool day a few weeks ago I experimented with progressively taping over the small intake on the front of the cowling that directs airflow through the fins on the bottom of the sump. I was surprised to find that just closing that off entirely resulted in a remarkable decrease in oil cooling. Even with an outside air temp of about 38 degrees a sustained run at full throttle would get the temps within about 15 degrees of maximum. I'm sure if I had been climbing it would have gone much higher. Until you get that thermostat, if you're flying in really cold weather you might try a single piece of clear plastic packing tape over the intake on the front of the cowl. Just don't venture far from the airport until you're sure it's not making too big a difference.

It is very cold over here.
