Coolant Flow Direction / E-fan Install
I am trying to find the best location to install a temp probe for an e-fan controller.
On every other vehicle I've seen, the heated coolant comes out the top of engine , goes into the top of the rad - cooled - out the bottom of rad back to bottom of engine. Makes sense - heat rises.
In this truck (2nd Gen 4.0 Frontier) it looks like the hot coolant is flowing out of the bottom of the engine as this is where the water pump and T-stat is. Can someone please confirm this?
The probe is the type that sits in between rad fins. It should be placed on the inlet side of the rad so it measures coolant that has done a full loop and not just the freshly cooled stuff on the outlet of the rad.

Re: Coolant Flow Direction / E-fan Install
The way I am reading the service manual I believe the flow of coolant is out of the cylinder heads, top of rad, out the bottom of the rad, into the block.

From the FSM: Coolant goes from the rad, to the t-stat, to the water pump, etc.. follow the arrows...FrontyFlyer wrote:I am trying to find the best location to install a temp probe for an e-fan controller.
