I've pretty much only bought OEM parts but was wondering if there was any known problems with using aftermarket sensors for oil and coolant temps. As you can see between the 10 and 12 sec mark my oil temp swings about 10°F in about a second. I need to check the wiring but will probably just change the sensor too. I had a step change in EOT recently and thought my oil cooler was on its way out but after seeng the changes as i'm watching it, I think its a sensor/wiring problem. Any one else have this? Edit to say this is on a 6.0.

To continue it will go as high as 213 and settle out. I want to know if there is any reliable place to put a sensor in that will measure oil temp. I have plenty of thermocouples and rtd's that i could adapt just wondering where they should go to get a reading or should i just pull the Sensor and put something else in there temporarily?

 

Sorry just realized i posted in the EX Forum. I think this might be more appropriate in the 6.0 forum. Is there any way to move this.

 

Stewart to the rescue! :-P

 

No, Toreador_Diesel.....

 

Thanks for moving

 

you could switch the two sensors and see if they are reading the same or diff I have always bought sensors from Riff raff diesel products ( OEM) never chanced the Aftermarket stuff (yet).

 

I have the same problem with the sensor readings. My EOT does not read correctly all the time. It will read about 170 and jump around a bit. All I need to do is touch the sensor wires and it comes back to normal. Just recently the ECT started acting up, again just touching the wires and it was good.


My logic, right or wrong, is the correct reading is he highest one. When I touch the wires EOT will go to 195 and stay there steady until the truck cools off.

I believe the solution is replacing the sensor and the pigtail. This will involve cutting the wires and splicing in the pigtail.
