More cooling system issues

[1987cp]

You can redundantly seal the back of the water pump, but it shouldn't be necessary.

And yes, the funky bolt/stud things were standard on all '79 and later 5.0 engines I've worked on. 9/16" deepwell on the nuts followed by 5/8" deepwell on the bolts themselves. They're the items I was commenting about earlier when I observed that it can be aggravating to get exact replacements (which is why I've sometimes resorted to using a regular bolt with washers to separate the brackets from the face of the water pump).


Oh, and I'm 5'9" and a bit larger around than ideal. The taller and ganglier type can probably work on the topside of a raised Vic or Marquis a good deal more comfortably!

I'm not sure I understand why I need to put the car on jackstands though. I was able to get under there just fine to change the radiator. I mean, other than disconnecting a few hoses under there.....isn't most of this job done from above?

Off course You donīt have to. I did it because I am quite tall and appreciated the extra access.

Torque specs are (5.0 engine) in Ft/lbs:
water pump to engine : 12 to 18
Fan clutch to water pump bolts: 15 to 22
Fan to fan clutch bolts: 12 to 18

Thank you both very much!

I will not tamper with the new water pump at all then.
It just got me to wondering.....when everyone was stressing about putting sealant on both sides of the main gasket.....and then I see a gasket in the pump assy that looks just like it but has no sealant on it.....why you wouldn't want that one sealed up real good too?
But....I'll leave it be.

I'm happy to say all seven waterpump bolts came loose okay. (just broke em' loose and re-snugged em')
All accessories and brackets are now out of my way.
I'm going to go drain the anti-freeze and call a night.
I put off doing that in case the job went south and I discovered I was in over my head.

I always repected how hard a mechanic's job can be (since my Dad was a one)....but it was different working with him (more like helping).....I always knew he'd figure it out.
Doing this on my own now.....I have even more repect for all of you that do this.

Oh.....and 1987cp......I'm 6' and go about 185 lbs.
.....and my back is sore from leaning over.....and I swear I have a permanant impression of my hood ornament in my gut.......LOL

Thanks mang!
I suspect your taller than me and given how sore my back is at the moment......I can now see why you'd want it up a bit higher as well.
But I'm managing.

[andymac0035]

Here's where I left off today. I'm going to tie off the PS pump to one side.
I got the alt sitting on the airbox tray. Thought it would be easier in the long run not having to unhook anything.

When I had a stock radiator in my car, I actually left a 2" piece of rubber tube permanantly on the petcock drain. It was just enough to direct the coolant below the rad support where I could catch it in a bucket cleanly.

[andymac0035]

Old pump is off.....time to clean things up.

Other than lots of time and fresh razor blades............

Is there any special trick for getting the old hard, brittle and baked on gasket off??
That thing is really stuck to the mounting surface quite good.

[andymac0035]

Well it's getting there....I suppose I should not be surprised since it's had 18 years of heat baking it on there.....but.....damn!

I can actually stand in the engine bay now.....that makes it a little easier.....(still sucks!)

Do I have to get every last little but if this off?

[mfmagicmike]

Was about time to change this one, it looks like Michael Jackson (may he rest in peace).

Scrape the old gasket of as good as You can, and hone the surface with an old brakepad (it works+++).
Most importantly,donīt forget that You/we want this job finished today.

Unfortunatley, I don't have an old brake pad handy.....Now I know of a good reason to keep one around though.

I got it all off....took a few more razor blades and my Dad's old carbon scraper.
Put a frash blade on at the end and tried to get things as smooth as possible.

I'm headed back out with a rag and some aclohol to clean the surface and let it dry before I put things in place.

Then planning on a light layer of RTV on each side of the pump gasket.

........and LOL.......I have tomorrow off.......

Called my usual parts store:

Water pump (new and supposedly with gaskets) = $47.19

Upper radiator hose = $13.86

Lower radiator hose = $19.22

Bypass hose (that lil' elbow) = $8.51

Also, they don't have timing sets listed, and I forgot to check on the gasket, but they do list just the chain for $13.88. How important is changing the whole set vs just the chain?

It's more effective to have the whole set changed because then you're starting with unworn parts.

[andymac0035]

I left the timing cover alone......I don't have another gasket for it anyways.
And honestly....I don't know if I'd be up to that task or not.

Pump is in and bolts are torque'd to 15 ft/lbs.
Hoses are back on but I'm having an issue there.

They are gates brand hoses.
The lil' elbow was too long on the small end...of course easily solved .....better too long than short.
The lower radiator hose is also a bit long and shaped a bit differently. I trimmed the radiator side and now it fits okay but I don't like the way it's bent coming off the pump.
My old hose is still in nice shape.....so I still have that option as well.

EDIT......pic of hose

[andymac0035]

All cleaned up, ready for the pump. (note I took the advice of laying the bolts out)




Pump in place.....bolts snugged getting ready to touque it down.

[gadget73]

Cool. The hoses are all made a little wrong. Its really annoying to have to trim brand new hoses so they fit right, but they're all like that.

[andymac0035]

Well, I feel a little better about the hoses then.....I honeslty wondered if I got the wrong ones by mistake.

Two questions:

-Should I trim that hose a little more? (maybe get some more of that bend out)

-should I re-use the OEM clamps.......or stick with the ones I have in the pic above?
