Hey folks.
I'm building a diff cooler rig and had a few questions:
1. Does the temp sensor need to be 'touching' the fluid, or can it be further up the line (before the pump, of course)?
I understand that the reading might be off by a few degrees, and that would prevent the pump from kicking in/turning off at the absolute 180ºF mark. But, in theory, the air temp inside the hose should be very close to the fluid temp. considering the short section of hose being used.
I ask because there are several inline temp sensors that I'm considering that would not only aid in installation (no extra hole drilled into diff cover), but also get the temp sensor out of harms way.
The other reason for moving the temp sensor is to get it away from the heat the diff. itself is putting out. While the fluid might be 175º, the housing and cover could still be at 190º, setting off the temp sensor and kicking the system on (or off when it's cold out).
2. What size radiator to use?
I've found several that would fit this application- 19"x7"x4" being the largest; 8.5"x3"x2" being the smallest.
Is there a minimum size required? Maybe in relation to how much fluid is in the system? (I'm running a little over 3 quarts)
3. In respect to question #2, I am thinking that more than the OEM amount of diff. fluid will be required when running a diff. cooler.
Is there a specific amount that needs to be added, or just follow the Comp. Coupe filling guide?
4. While the Comp. Coupe runs a Tilton pump (and those rock the hizzouse) are there any other comparable options out there?
5. -06AN and -08AN seem to be the two hose sizes of choice.
Any advantages/disadvantages of one over the other (aside from fluid movement and price of hose/fittings)?
Thanks for any help or insight you can give.
I appreciate it.
