1998 Ford F150 4.6 - Heater Hose Change
Looking at replacing the 2 heater hoses above #4 cylinder on a 98 F150 4.6. Would appreciate any info someone could give me on the best way to approach the R & R (special tools needed, cautions, etc..). Stay with the QD set up or use the hose/clamp set up without QD. Believe the current hoses to be the factory original ones. I've read about the quick disconnects & to replace with clamps vs. the QD set up. Thanks.

If they're not leaking, I would leave them alone. My truck had 185K miles on it when I pulled the engine (in fact, I haven't yet put the new engine back in yet) and they weren't leaking then. The only reason I might consider replacing mine is because the engine is out and I've got plenty of room to work. Like I said, if they're not leaking or giving you any trouble - put it off for another day.

Okay nope nothing special as far as tools, yeah , I wouldn't mess with the hard line behind the pump unless it is leaking - Thers 2 bolts that fasten the line to the back of the head..My fix on that line is in the books , but it never made the TSB's - it should have..Fords sent me the procedure , not the parts for free Damnit (that's what I was hoping for lol)..
If you mail them and blow a little sunshine up there a$$ about there product , they bend over backwards to help..
Anyway, when you order your intake gaskets make sure whoever orders them for you gets you the right one's - Fords moved the dowl holes around quit a bit on the heads and gaskets thru the years..
When tightening down the manifold , make sure you do it in sequence and only a little at a time for a good seal..
Check out the tops of your heads for pits around the water jackets - fill with aluminum filler if applicable..
Good Luck.
