1997 Mercury Grand Marquis (W). After 92000 miles, it finally happened....my
manifold devloped a crack on the bottom of the intake crossover. (article
02-2-2) Luckily I wasn't too far from home so the tow charge was fairly low.
(funny how the radiator hoses last longer than the manifold)
I would like to completely drain the anti-freeze before starting this
project. According to the instructions there are anti-freeze drain plugs on
the block that can be removed. The only things I see toward the bottom of
the block are some 10mm bolts (looks like 4 per side) and also freeze plugs.
Are these bolts the drain plugs?
Also, as far as relieving the pressure in the fuel rail, the instructions
call for a MFI pressure gauge (T80L-9974-B) is there another (safe and
cheaper) way to relieve the pressure?
And finally do the injectors just unscrew out of the manifold?
Any other hints in replacing this would be helpfull! (I've ordered "$$$ THE
KIT $$$" from Ford.)
Thanks in advance for the help!
