Need ideas on where to tap into for EOT and ECT

[RoCkfiSh363]

Got some digital Autometers today and need to hook them up. I need to know where to put my Oil temp sending unit ( tap the oil pan?) and I need to know where the best place to put the coolant temp sending unit ( drivers side drain plug?) Thanx in advance guys.

For your oil temp get a billet oil filter cover and it will have the 1/8th npt tap in the top for the oil temp sending unit. As for the coolant temp I think it gets spliced into one of the return lines going to the degass bottle. I don't have the coolant temp gauge on mine so I'm not exactly sure on that. But the oil temp goes onto the oil filter cap or there is a test port on the oil cooler housing that can be drilled and tapped for the temp sending unit but it's not easy to get to and should be done while replacing the oil cooler though.

Thanks for the reply man. I always thought that port on the billet caps was only used for oil pressure. Also, I was wondering if anyone knew what the coolant oil temp delta safe zone was? 10 degrees within eachother?

No higher than 10 - 15* when going 65 mph on flat ground with the truck at normal operating temp. Should be lower than that but if it's in the higher realms of 10-15* get ready to replace the oil cooler cause it's clogged.

15* is the allowed delta. Block drain is an excellent choice for location of thee coolant temp sensor. For the oil temp sensor get a T and run it under the Pressure switch.

Can the ect sensor be t'd into a radiator or heater hose and be accurate?

FWIW: My oil temp sensor is in the top of my billet oil cap; My ECT sensor is in the block drain on the drivers side. Works well.

I think i'll be using the block drain for my coolant sensor, as for the oil sensor not sure. Does the billet cap give accurate readings?

The difference is on the billet cap is your oil temp is being read post oil cooler where as at the oil pressure switch it will be pre oil cooler so you will have different oil temp readings.

The billet oil cap is read post oil cooler, just like the OEM EOT, and EOP.

Oil gets pumped up from the oil pump to the oil cooler, then goes thru the filter, and then gets divided to go to the reservoir/crankcase/turbo feed/EOT sensor/EOP switch.
