i gotta 90 f150 with a 300 i6 and i was thinkin bout doin an efan swap i wasnt for sure how to remove the mech fan and i was also considering doin the timing bump i saw the post on the bronco i was wondering how different it wuld be on the 300 i6 like spark plug gap and things like that

 

as far as the fan goes break the bolts lose on the front of the fan, then remove the serp belt and finish unscrewing the bolts, then seperate the fan from the pully and you will have to put the pully back on you might need to get some shorter bolts or use some washers and then just put the belt back on and hook up you new e-fan, not to sure about the timing though

 

As far as the timing bump goes, it is exactly the same on our motors. My gap is at .055, and I've got 8mm wires, and a brass cap and rotor button, with the msd blaster coil. You don't have to buy an msd cap, any brass terminal cap will work alright. I advanced mine to 16 degrees btdc, the stock setting is 10 degrees. It's the same procedure, just make sure you disconnect the spout plug, and use the correct timing plate and mark on the crank pulley. Its the opposite of the one you would expect on both parts haha. The big notch on the pulley is for balancing not timing, it is a small etched line, and you need to use the timing plate on the passenger side below the alternator

 

wat if there isnt much room between the radiator and the front of the fan will i have to remove the radiator?

 

your better off just trying to get your hands in there best you can, u might bust up your hands a bit but its less work, is there a shroud in the way also?

 

yes there is a big ole shroud in the way lol idk how it comes out tho lol any ideas

 

Your fan should have just the large nut that holds it to the water pump. Some vehicles require a special tool to remove it (just a very skinny large wrench) but I was able to use channel locks. You won't need to do anything with the pulley, it's held to the water pump with 4 separate small bolts.

 

On mine it was the 4 small bolts that held the fan and the pully together to the water pump

 

Is yours an I6? All the inline sixes I've seen had the large nut.

 

Oh i just figured they were the same thought i remember doing one where it was the 4 bolts i guess im wrong but no i have a 5.0 sorry
