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 $15 for the cap, which seems ridiculous, although the local NAPA says they can't get them for any price, so rarity is probably inflating the price. Something I can get in a timely fashion to Edmonton Alberta, in particular. The water pump I'm not so sure about, but my neighbor has offered to assist in the operation. I've got the full-service manual as well, but that might not be the final answer either. Ah, well, the library has a Chilton's and Hayne's guide, I think. :) Clint "Clint" <nobody@nowhere.none> wrote in message news:igIPg.555744$iF6.409921@pd7tw2no... > So we had a really hot day here awhile ago, and I ended up overheating my > Jeep Comanche (4.0l engine).

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...
