1990 Ford F150 6 cyl 4.9L, or 300 cid, Fuel Injected Engine
I don't have a clear understanding of the history of this truck. The
owner is offering it to me to use if I can fix it. I really need a
vehicle now for work, so I'm trying my best to get it going.
After doing a number of repairs to the truck, and getting it going
sort-of, I discovered two leaking freeze plugs, the front and the rear
(on this inline 6). The leaks are too large to ignore, and the rear
one pours directly on the starter. (The truck is missing the radiator
cap; this is probably because the former user misplaced the cap
because of constantly adding water, or he or she didn't want to
pressurize the cooling system.)
The freeze plugs are very hard to access. I'm not even sure it's even
possible to reach them with the engine still in the truck. So I'm
wondering, is it possible to change these freeze plugs without
removing the engine?
I'm not an auto mechanic, and I don't have a lot of tools. But I have
a mechanical aptitude, and if it can be done, I can do it. But I need
to know if it's reasonable to change them without removing the engine.
I need to know how to proceed. Someone with experience with the engine
I have to decide on a course of action. I would appreciate any
recommendations. Has anybody changed these freeze plugs?
It's a 1990 F150 with a 4.9L fuel injected engine.
