After searching i have not quite yeilded the answers i need..
My swap is done, but my fans are wired to run all the time. what can i do to make them come on and off at a certain temp? should i buy a kit like this: Two's R Us Fan Relay and Thermo or can i figure it out without dishing out the cash? Fuel pump relay... do i need to do anything with this? I think its on all the time, should it not be? etc. i don't want to burn the pump out.. its an SW20 pump and i usually run around 45-48psi on average when driving.

if you have a gt radiator, then you should just have a plug there that connects right to the radiator, without having to do any splicing or cutting. then you fans will come on/off as needed.
as for the fuel pump, you dont need that relay. all it does is switch from high to low voltage for the fuel pump. ive been running mine on high for about 3yrs with no problems. -------------------- 15PSI - 30MPG - Megasquirt Tuned

Now onto the fan.. well i have the plug etc etc. but when i finished the swap the fans never came on. and then i remembered, that doc had flagged a wire in the engine bay on the harness that he told me was for the fan relay. I just gave this wire 12v and now the fans are on all the time. In the fall this was fine, but now since it is getting cold as balls (finally) around here.. the fans cool the engine too much and i never get over 140 degrees in the top radiator hose. If im on the highway she won't leave safe mode because she never warms up enough etc. also i have no cabin heat since the coolant never gets up to a decent temp. |
