Greasecar wvo temperature sensor/sender

Does anyone know what temp sender they use? I don't want to shell out $65+shipping if I don't need to, but I want my copilot to work with the temp sensor.

If anyone knows I'd be very grateful... if you know the resistance range (ohms) that would be equally as useful.

Thanks!!

the readout guage on mine went out so i did some shopping for a temp sender/gauge combo the same style as the one GC provides... $65 is a pretty good price.Maybe cheaper if you are just looking for the sender alone without the readout gauge.

No this isn't the gauge combo. Its the sensor and Tee for the copilot. Attached a photo.. It really shouldn't cost that much just for a sender? Some of them go for less than $12 on eBay.

I see.. You need just the sender. I need just a readout gauge for mine.. My sender is fine.

From my experience the oil temp gauge is kinda unnecessary. First, it doesnt give an accurate measurement of the oil temp unless there is oil FLOWING through the sender ( in-line Tee configuration). Second, there is no way, in my configuration to have oil flowing through the sender without switching the fuel supply to the engine. Whats the point of having a gauge to tell you if the oil is hot enough to switch if it can't tell you how hot it is until you switch? for manual switching it wasn't long before i knew how long it would take for the oil to heat and be ready to switch without the temp gauge.

I understand that you are wanting to use the "co-pilot" that automatically switches and all of that. just be aware of that flow problem.

Long story short... I'll entertain an offer for The GC temp sender tee.

That's quite interesting since the copilot is designed to switch the to WVO once it reaches the desired temp. You're saying that temp is artificially high (because of lack of circulation) or is it low? The only solution for that would be a return line to the tank so it flows constantly..(obviously a pump as well). No way I am doing that now, but possibly in the future.

I probably don't need this specific one in all reality since I can run it on manual mode if I like, however I wanted the option of having it automatic.

Sort of a side note but I am planning on setting up an Arduino and LCD with several temperature sensors throughout the system so I can keep track of everything in one small place. This way I can find any problem areas during the summer, and more importantly the winter.

I would definitely be interested in your sender. I am not sure if they are the same. I believe I asked greasecar and they said the two are different. Would you be able to check it and let me know the identification numbers(probably letters too) off the side of the actual sender?

I already have the water sender w/ tee, and I have a gut feeling they are the same model for both..so if it matches let me know what you'd let it go for. You can PM if you'd like.

Thanks a bunch

I wrapped my temp sender around injection lines 2" from head.It gave me a more accurate measure,and I used injection line heaters to make sure oil didn't loose heat thru I.P.

The Temp sender and the basic GC setup ( plus a cleanable pre filter and a hot water l/O valve).

I'll have to do that with my secondary gauges that I am using with LCD box. Otherwise my copilot would never get a reading.
I'll have to wait on injection heaters until I replenish the cash reserves at the end of the summer, and have some time to research.


I pulled the coolant temperature sender from the greasecar tee. Isspro R8923-03. Since most of these senders are designed for both water and oil, I am going to assume this is the same model used in the oil temp tee. Also looking at the photo they look identical.

Now I just need to figure out the ohms rating so I can integrate it into my other display..surprisingly I cannot find it anywhere. I am going to post what I do find here since I believe this is some what useful for those working with the copilot, and might save them some research time.

I did find this ISSPRO.com - Quality Gauges, Tachometers, Speedometers and more! however the pdf for the model has no info about the resistance. The troubleshooter at the bottom does have a bunch of info, but states its for the EV product line. I am waiting to hear back from Isspro customer service for more details.

How I understand it, the coolant temp sensor controls auto switch to veg and the oil temp sensor controls electric heat. You can set up injector line or vegtherm style electric heat and have the copilot throw the relay at your specified oil high and low temps.
