Diff. temp. sensor?

[LongrangeLauber]

So I just got my mag hytec differential cover in last week (for whenever I get around to regearing) and it has a 1/8th NPT insert for a differential temp. sensor. I went searching for a sensor, but I cant find a sensor that is long enough to touch the fluid from the top of the cover, considering you don't fill it all the way with fluid.

 

So, does anybody know where I can find an extended sensor that will give me an accurate reading? I really just wanna pay attention to the fluid temps. when I regear to 4.88's and the gears are still being broke in, plus I will use it for towing

 

Thanks

the pml differential covers have the fill hole on the top and drain hole on the bottom. The temperature sensor they locate slightly below the top fill hole.

It sounds like your differential cover did not compensate for the sensor from what you describe......

 

Scooby.

 

You should feel the fluid at the top fill hole, there fore the sensor does not have to be long.

I read about your Mag hytec cover and it says it comes with a dipstick hole, not for a sensor..

[LongrangeLauber]

Comes with the drain hole, dipstick hole/fill hole, another hole on the face of it to help you get your fluid to the proper level, and a 1/8th NPT hole for a sensor.

 

Unless mag hytec makes their own sensor that isn't listed anywhere on the web...

Unless you just want another gauge to look at, I don't see the need for a diff. Temp sensor. I don't think the ZL1 HAS A diff temp sensor though it does have a diff cooler though that's a high performance machine for track performance.

Towing, it's a pretty steep gear, 37's (when i have the $) and highway driving. And I do all of that at once sometimes so it would be nice to monitor it, especially during the break in period (not towing of course). Plus I don't have a light foot haha

 

The ZL1 also doesn't have a steep gear like that, so not as many rotations which equates to less heat buildup. Plus as you said, it has a diff. cooler

Here is a pic of the top of the cover that I was talking about:

 

Left port is the temp. sensor port, the right is the fill/drain plug hole

 

 

It is all the way at the top, unless the sensor is suppose to just read the fluid as it is flung up at it, which wouldn't make sense to me, cause it could really throw off a reading

Most diff covers that I have come across have the fill hole located in an engineered spot so you can't over fill the unit with gear lube. That one being on top of the cover scares me a little, especially since it looks like it would hold a larger amount of volume of lube than stock.

Maybe that is the hole on the backside where it says mag hytec. I tried uploading the pic but the file was too big

One of the purposes of the hole in the back is to help get the level correct according to Mag's own website

 

 

 

This it?

I took my own pic so I guess the file size was bigger. And yes that's the cover

[LongrangeLauber]

And that's what I read. You fill it from the top and keep that plug off.and when it starts to our out then you are at the proper.level

+1 on that, if you are worried about high differential temperature, use a synthetic 85W-140, your temperature problems will be non existent.

Is it OK to run 85 weight oil instead of 75? Cause I normally run 75W-90 mobile 1 synthetic in it but if the higher weight will help the steeper gears stay cooler I'll just run that instead

[Black02Silverado]

The 75w-90 should do just fine as long as it is a synthetic. If you want to go heavier, then I would go up to 75w-110. No real need to go to 140. AMSOIL's Severe Gear would also work well.

Got the differential cover axle flange all cleaned up. Just need to get the axle housing sand blasted after the 4.88's and Detroit locker get installed!
