LJ78 Prado BIG Cooling Fan Upgrade (1 Viewer)

[GTSSportCoupe]

Hey Nick, thanks for the input. I had done the clutch fan mod, but am trying a brand new one. Seems to work about the same as the old one post-mod. I do lose a little bit of coolant over time I think, but most of the time I can pour back in from the overflow, and that fills it up. I think it depends how hard I push it over the hills.
I wanted to do most of the GTS mods before I change the head, as I only want to do it once. I next want to remove the EGR system, and will work on larger exhaust this summer.

Just remember, I'm only learning as I go! If you really want a permanent solution that is bar none the best, go to the Evans waterless coolant. After everything I've done, I've realized that is the only sure solution for these engines. You could run it in the red with that stuff and the head will be just fine.

I am interested in the specs for the machined spacer as well. Did that ever get posted? In the mean time I have done a search on the internet and come up with this. Looks pretty good no?

The spacer from the ebay link is 3" long.

GTSSportCoupe Checking in to see if anything has changed since doing the upgraded fan? I know it's been a while and I have a different truck/engine, but I'm looking at doing a clutch and fan upgrade and wanted to know if there is a better option for my 1KZ-TE other than the 10 blade fan.....

Has any just tried adding water wetter to the cooling system for major temp drops?
