Oh it is MUCH, MUCH worse then that!!!

Primary fan comes on at 216 and the secondary at 224. Stupid!!!

BTW - the PCM starts pulling timing at 200 degrees. 20% by 210, 40% by 230

Programmed in heat soak!!! Absolutely asinine Ford!!!


My operating temps hover in mid to upper 160's when moving. The engine just loves it. My engine gets no higher than the low 190's in stop and go traffic. (it's been 90's with 90% humidity here too so far)

Even at that the primary fan hardly ever runs (never if the car is moving) and the secondary has never kicked on to my knowledge.

Yes I have the fans kick on early (185 for primary/195 for secondary) and for those that asked No you can not just build a simple relay circuit for them. The stock harness and setup will not allow for it.

The SVT radiator combined with the 60/40 water/dex-cool mix and some water wetter works just amazing for heat control!

2000 SVT #674 13.47 @ 102 - All Motor! It was not broke; Yet I fixed it anyway.
