More Is Better
The fitting you're looking at is an additional bung I had Canton add to the tank. The coolant temp sensor you see is a normally open switch that senses I/C coolant temp and closes to turn on (2) 5.2" Spal fans on the Afco H/E. There's no need for them to run when the temp is below a certain temp.
Yes the tank is a custom tank, but it is only custom because of that additional bung I requested. The I/C reservoir is basically just a 80-237ND reservoir with the additional bung.
If I were to purchase this reservoir (or any other reservoir) again, I would request the outlet fitting to the I/C pump to be moved from the rear of the tank (next to the firewall) to the front of the tank. This relocation would provide additional clearance for the Performance Automatic pan's dipstick tube and JDM transmission catch can.
Here's a better picture of the outlet fitting to dipstick tube clearance issue I just mentioned. You'll also notice I replaced the black reservoir cap with a red reservoir cap - just my preference. This picture also shows the previously mention I/C coolant temp sensor.
If you are planning on ordering a custom tank, it really isn't that much more expensive and you can get the tank configured the way you want it - just ask for Brandon in Sales @ Canton.
Concerning the I/C pump - it is mounted in the same location as originally per Saleen, right in front of the W/W reservoir. The reason the location may look odd is because I have a GT 500 fascia.
EXCELLENT information...thanks much!
