Water Pump removal 239 V8
 

Hi, I am new to the forum, and also have just bought my first Ford pickup. A 1950 Ford F1 (actually a Canadian built F47) with a 239 Flathead v8. I need to replace a water pump. I am going to replace both of them. They are mounted to the front engine mounts. Is there a spot where I can position a floor jack, so I can remove them or do I need to get an engine hoist?

Welcome to the forum. Glad you stopped by. You can place a wood block under the oil pan and use your floor jack to raise the engine enough to remove the water pumps. Be sure to disconnect the motor mount from the frame first. You only need to raise the engine about an inch to get the water pumps out. Tell us more about your truck. Let me be the first to say "we like pictures". Looking forward to following your progress.

When removing the water pumps remember there is a bolt inside the water inlet - I can drive one crazy if you forget to remove it.

Thanks for the quick replies and the tips. I will try doing this job over the weekend. And here is a link to some photos of the truck.

that's one beautiful truck. enjoy.

The other thing is to swing the radiator away from the pumps (either up or to the front) so you can get the hoses off. Not an easy task. May be easier to just pull the rad (and the shroud if you have one).

I am finally going to work on the water pumps today. I am looking at the oil pan and assume I need to put the block of wood just behind the pulley.

The deepest part of the sump is better, with a piece of wood between the jack and sump. Don't raise the engine any more than needed to unload the motor mounts.

Thanks, sorry for more questions, but do you mean to the rear of the oil pan behind where the oil plug bolt and the 8 surrounding bolts are?

Yeah anywhere in that flat area will do fine.

I know, bringing up an old thread... but I may be doing this soon as well. I had the same question about where to put the jack. However, do you have to jack it up or just hold it in place? Can't you just take out the motor mount bolt off(which you would have already taken nut off for) and slide the water pumps out?

If/when i do this I'll be replacing the motor mounts assembly since they'll be accessible and cheap.

you do need to support the engine. the only points that hold up the engine, transmission are the two front waterpum/motor mounts and the transmission mount. you don't need to raise it much, just "take the weight" off it. haven't read back into the thread but usually a chunk of 2x8 strategically placed under the oil pan with a jack put push it.

Thanks! Yes I'd need to take weight off motor mounts which would require maybe 1/2 to 1 inch... maybe that's what they meant.

As for the placement, i would think i should avoid the oil pan cleanout (circle with bolts) for fear of dislodging seal?

The oil pans on these are made of serious steel, you won't hurt anything. The other areas aren't flat enough, jack can slide off or tip over. If your "seal" on the cleanout is like most, it leaks like a sieve anyway.
