Re: 88 Jeep Comanche cooling issues
The diagnosis from the garage is a new water pump and new bottle/cap. They
are recommending replacing the thermostat as well, at the same time. The
thermostat and bottle/cap are no-brainers in terms of how-to (I think; I've
done the thermostat before), but does anyone have a cheap source in Canada
for the bottle? They're quoting $100 for the bottle, and $15 for the cap,
which seems ridiculous, although the local NAPA says they can't get them for
any price, so rarity is probably inflating the price. Something I can get
in a timely fashion to Edmonton Alberta, in particular.
The water pump I'm not so sure about, but my neighbor has offered to assist
in the operation. I've got the full-service manual as well, but that might
not be the final answer either. Ah, well, the library has a Chilton's and
Hayne's guide, I think. :)

Re: 88 Jeep Comanche cooling issues
I believe you either need a bottle 'or' a cap and not a pump unless it
is leaking out the bottom of the snout under the pulley.
If the bottle is cracked and you have to buy one, then you may as well
get a new cap. More likely the cap washer is just old.....
If this only happened once in hot traffic, then I would almost suspect
the old cap just wasn't tight enough.
You can do a visual inspection yourself. If your bottle has a long time
seep or crack, there will be a green stain by the crack. If the cap
washer is bad, there will be green stains around the rim. If it was a
one time thing because the cap was loose, it should be clean. If it
actually overheated because you have a bad pump or t-stat, then the top
of the cap will have stains.

Re: 88 Jeep Comanche cooling issues
No, it's happened before. The bottle is cracked, as well, apparently. The
bottle was my first choice in replacing; I just figured something else was
wrong too, as I doubted the low flow would have been caused by a slightly
leaking bottle.
And I suspected the water pump was leaking as well (drips under vehicle
overnight), so I'm not entirely surprised by that.
Any suggestions for Jeep parts up here in Canada? I phoned a couple of
local places and got a couple prices on the water pump, and they weren't too
ugly. At least I'm a little more informed about what I'm getting into,
anyway. And I found at least one US source on eBay for the tank (around
$30), but it looks like they'll only ship UPS, which sucks up here to
Canada. The one parts place I talked to suggested a wrecker, but with the
issues I've heard with the tanks, it's not something that I really want to
replace 3 or 4 times trying to get one that's not cracked or anything.
I did find this link on the Net, WRT replacing the pump, if anyone else is
interested:
http://jeepin.com/features/waterpump/index.asp
Looks pretty straightforward on there, with the possible exception of the
4th bolt holding things in place. Of course, I'm expecting my mileage to
differ. I'll have to weigh the labour charges the garage gives vs. the
money I can make doing some contract work...

Re: 88 Jeep Comanche cooling issues
No, it's happened before. The bottle is cracked, as well, apparently. The
bottle was my first choice in replacing; I just figured something else was
wrong too, as I doubted the low flow would have been caused by a slightly
leaking bottle.
And I suspected the water pump was leaking as well (drips under vehicle
overnight), so I'm not entirely surprised by that.
Any suggestions for Jeep parts up here in Canada? I phoned a couple of
local places and got a couple prices on the water pump, and they weren't too
ugly. At least I'm a little more informed about what I'm getting into,
anyway. And I found at least one US source on eBay for the tank (around
$30), but it looks like they'll only ship UPS, which sucks up here to
Canada. The one parts place I talked to suggested a wrecker, but with the
issues I've heard with the tanks, it's not something that I really want to
replace 3 or 4 times trying to get one that's not cracked or anything.
I did find this link on the Net, WRT replacing the pump, if anyone else is
interested:
http://jeepin.com/features/waterpump/index.asp
Looks pretty straightforward on there, with the possible exception of the
4th bolt holding things in place. Of course, I'm expecting my mileage to
differ. I'll have to weigh the labour charges the garage gives vs. the
money I can make doing some contract work...

You may be able to glue the bottle, depending on the size and location of
the crack.
