Whether I liked it or not (and definitely not because of sub freezing
weather), the water pump on my 2000 Mercury Sable, which has Vulcan 3.0
V6 OHV engine, went bad earlier this week. After viewing a variety of
different procedure videos and some written material, I removed the pump
yesterday and I am awaiting the new pump and thermostat to arrive today.
As I replaced the intake manifold gasket several years back due to a
failed PCV valve (which I couldn't get to without manifold disassembly),
I had not run into either of the issues I'm about to ask about.
So, I have some questions. With snow on the ground today, it's unlikely
I'm going to be able to complete the job until tomorrow so that give me
1) What is a decent way to clean the gasket area on the engine? I looked
at a variety of videos and read some posts, but can't make up my mind.
One gentleman takes a hose and washes the entire area down, but not sure
I'd want to do that. On the other hand, there is coolant residue all
around the area that will have to be removed. What I am thinking, which
I also read, was using a moist Scotch Brite non-scratching pad to gently
scrub the gasket area to both remove gasket remains and the residue.
Thoughts would be welcome.
2) I was going to clean up the gasket bolts and apply both anti seize
and thread sealant to the fresh bolts, but upon removal many of the
bolts are oily or sludgy. Hard to find a proper solution, but the mess
is obviously coming from the mounting holes. Should I just reinstall
as-is and, if not, how do I go about cleaning those holes?
3) I am doing this procedure with the car on 9" car ramps to get better
access of course, but I am concerned that not all coolant was drained.
I'm thinking that, during the flushing process (where I'll drive for a
few hours with a cleaner and water fill), that I will drain most of the
water with the car on the ramps first, then follow up with the car on
the ground with a pan to catch the rest. Is this really necessary, or
was the coolant drain sufficient on the ramps? (EDIT: I don't think this
will work because I won't be able to back the car off of the ramps with
most of the coolant drained! Looks like I'll have to do it all with the
car flat on the ground.)
Thank you in advance!
