i tried a spal 3500cfm electric fan on mine and had it completely shrouded as well and it was not as good as the std engine driven fan. after lots of r&d in my mates shop we have found the flex-a-lite engine driven fans to be the best suited step in cooling. we have had heaps of different cars in complaining of overheating, most running thermo fans, changing to these fixes it every time. these are what you need for the p38, retain original shroud and remove viscus fan and hub.

So changing to a fixed fan... nothing wrong with that - worked great in dad's 77.
I wonder if the thermo fan kicks in at a too higher temperature then. I do like the thermo fan design though, with the ring around it.

I use Ford Falcon EL V8 twin thermo fans with integral shroud to cool my Disco, and AU twin thermos on my 4.6 SD1. Easy to fit, massive cfm and cheap at $90 each from the local Ford wreckers. You need to trim the plastic shroud slightly but they fit like a glove on those two vehicles (EL fans are slightly bigger and have more blades). Run much cooler than they ever did with mechanical fans.
Thanks Traco, It looks like I've just bought myself a set off Gumtree (twin 8 blades with shroud)- I pick them up tomorrow for $20. I figure at $20 it's worth a try ;).Quote:

with the spacer the fan is still a fair way from the radiator. the back of the fan just protrudes from the rear of the shroud and the fan blades are roughly 1&1/2" from the leading to trailing edge (thickness)Quote:

I ran a fixed fan on my 4.6 for a short time, it had an overheating event and one of the problems was a faulty viscous coupling which wasn't stiffening up with temperature.
Anyway, while I was waiting for a new one to be shipped from the UK I took the old one off and drilled several holes straight through it and put some small bolts through to permanently lock it.
The cooling was great but it noticeably sapped engine power at high revs and made a hell of a noise, it also kicked up lots of dry dust and dirt from under the car, even at low speed.
Its running great now with the new viscous coupling and new fan, no temperature issues at all. I did put an extra temperature sensor into the hose from the top of the engine to the top of the radiator as I prefer to have multiple sources of information to avoid a repeat of the overheating as the blocks will only recover from a couple.
