I have a question for anyone that's has an older style Ford chassis rv with a  460cu inch engine in their rv. I can't seem to get an answer, even from the dealer. My question is, the heater bypass hose that goes from the water pump to the engine block. Its a small hose and I wonder if it is possible, or if anyone has actually tried to change this very important hose, without having to pull the water pump to do this. I'm not sure if there is enough room to somehow squeeze or fit this hose between the block and pump. I really don't want to find out the hard way by cutting the hose off and then finding out that was just not a smart thing to do. Any help or advice would sure be appreciated.

                 Thanks

A very good question. Looks really tight; maybe too tight.   Never done it on this model.   Members what do you say?? Can it be done?!!

 

WOW! What a great response. Yes, I was afraid that's the way it was going to be. And I do agree, original water pump and I do need to change the belts, fluids, etc. So a new water pump ,hoses, etc. it shall be. What was Ford thinking when they designed an engine like this? The engine over the years has been bullet proof with only a carb change to a trusty old AFB and not much more. Again, thanks to everyone to the great response.

I have changed 3 or 4 of these over the years in misc Fords, and Its almost impossible to change it with out removing the water pump. It looks so close to being able to just cut it and then squeezer-ating another in there,,,, It dont work.,,  Some early Chevy 305's were same way..  water pump removal is the way to change it.

Ain't that a crummy design. Guess may as well put in a new high capacity water pump and change the fluids and all important thermostat at the same time.      I guessed wrong. i thought he might just be able to do it so glad to know we can't.

, I  could never get it to bend enough and squished enough to get both ends of hose on,  Mind you,, I did try and I could never get it to cooperate.

I would drain the antifreeze,pull the radiator,change out that old water pump and install a new piece of heater hose.Plus all the other hoses and belts.This would be a good time to check your transmission lines and also replace your engine fuel pump and thermostat.Doing these things now is much better than later when it might be inconvenient.

 I owned a ton of those DARN 460 Fords over the years and HATE THEM LOL. As I recall if you have the fittings greased and cut the hose just a tad short its possible to change that hose but it will still drive you to drink grrrrrrrrrrr. HERES WHAT I STARTED DOING. Each time I bought a dern 460 Ford the FIRST thing I did while at home in a nice clean shop and warm weather was to:

 Pull the radiator and replace it with a 4 core heavy duty unit,,,,,,,,,,,(factory was only 3 core)

 Replace the dern water pump n be done with it cuz they will all go out.

 Refill with distilled water......anti rust,,,,,,,wetting agent,,,,,,,,,, and super cool

 Allllllllll new belts n hoses

 The you can drive them dern Ford 460's for years trouble free

 If you have to change a water pump on the road in a parking lot when its raining grrrrrrrr There are 1000 bolts on that water pump and you have to remove water pump and PS pump and alternator n smog pump and AC and they all have belts and all those things are all bolted together grrrrrrrrrrrrrrrrrr grrrrrrrrrrrr I hated them 460 Fords lol

 Sorry for the rant, but I learned all this the hard way over the years

Yup, that is definately the way to go John T.  You just know it's going to go out. so, better to do it now.

Is there a timing belt in that engine?

Hi Kevin,this engine has a timing chain made out of steel.

so should it be changed while you have the water pump out or not? pardon my stupid question. I know a lot of times they change the timing chain along with the water pump in some engines.

If your in that far,, its a good idea to go ahead and change the timming chain and gears with fresh gaskets and front seal,,, that way ya wont have any problems in that area.
