Cummins coolant temperature sensor

[Max Hubrich]

Hi Monaco Mama and All you neat Guys and Gals,

I have a friend that has a '98, 40 ft, Dynasty with the 330 HP,6CTA 8.3 engine. The coolant temperature sensor has gone bad. Anyone got a replacement part number from NAPA, CarQuest, etc??

Thanks,

Hey there Max! How are things going for you?
I am also going to move this down to the "Cummins" forum for more exposure...

It is great to see others trying to help others...That is what iRV2 is all about!

Thanks M Mama,

George, my friend, said that Cummins does not supply that part. The Motor Home manufacturer installs it

[Ecker]

I think he's part way right. Cummins ships bare engines to chassis builders (no oil, coolant, accessories, etc) unless special order for some particular item. The chassis builder sends the engine down a so-called "dress up line" and adds the radiator,fan, coolants, oils, accessories, etc. The sensor would probably be installed at that point; I just don't recall tonight. I'm having a CRS attack.

Max, I've been Googling and I can't find it. I thought I'd try my luck.

Maybe a call to the Monaco Tech line might help come up with a replacement part number.

Hi All,
George also needs to know the location of the sender (sensor) on the engine-- any ideas?

I know there is a sensor on my 01 Dynasty 350 Cummins in the side of the coolant tank that sits above the engine. At least, there is one coolant sensor there...not sure if there is one in the block or not????? Mine is problematic, in that it will display a low coolant light on the dash when there is plenty of coolant...then it goes out...I need to replace mine also!!

teofff,
Looking at the sight glass sometimes provides a false view of coolant quantity. Consider taking a rod and placing it into the expansion tank. Determine how much coolant is really in the tank, when cold. Many times the sight glass will show the coolant color, but the coolant level is way beolw the glass. It may be you do not have enough coolant, when cold, to cover the sensor. When the coolant gets hot and expands it then covers the sensor.

Gary:
Unless I'm missing it, I don't see a sight glass....the sensor sits on the side of what I would call a coolant resevoir...which, I might add, is very difficult to see through. Only when cold can I remove the cap and put a rod down to see where the coolant level is......I beleive my level is high when cool, and I will still get the light intermitently...

just spoke with Monaco about it. the sensor is still available on my 95 40ft dynasty for a whopping price of $137.44.then u have to buy another wiring harness to go with it from ford. that part # is f6hz-14a382-aa for around $50.00. goin to do some more homework and find the coolant sensor from another source.

[Perry White]

The new type coolant is screwing up the sensors. Cummins sensors are $230/wack. I just disabled mine in the ECM.

67WildBill does your sensor look like the attached picture? If so you can get it from your local Ford dealer for under $30.

Part number is Ford Coolant Sensor part XC4Z10D968AA
