Re: 88 Jeep Comanche cooling issues
 

Make sure you get the correct pump. Somewhere along the line they changed
to a reversed impeller. I understand it is quite common for the reversed
and non reversed pumps to be in the wrong box at the parts house. They are
easy to tell apart as the reversed models will have an 'R', "REV', or
'REVERSE' stamped into the impeller.

Be sure to replace the thermostat and cap while you are in there, they fail
at the most inopportune times. Get the correct thermostat.

Replace the factory springs clamps, they are a bad design to begin with and
cannot be retensioned. Stainless steel screw clamps are cheap.

While you are doing all this you should probably flush the cooling system,
adding a flush-n-fill kit makes this child's play.

Finally, be sure to use the proper coolant.

Mike Romain can give you pointers for Canadian suppliers, generally speaking
you can get any Jeep part you need at Canadian Tire, The Beer Store, or Tim
Horton's.

In many smaller Canadian towns that is all in one building.

Re: 88 Jeep Comanche cooling issues
 

I've had nothing but grief with Canadian Tire, and their local parts
department. I replaced my thermostat about a year ago, and I was in and out
of there at least 3 times trying to get the right part before I finally
yanked out the old one, took it in to them, and found out they didn't have a
matching one. Went down to the NAPA store, and was out of there in 5
minutes with the right one.

If nothing else, I've got selection. The local garage is a decent place in
a small town, so if he starts screwing people around, word will get out
quickly, I'm sure. Then the Canadian Tire is about 15 minutes away, with
the NAPA and a Parts Source (haven't checked them out yet) about 17 minutes
away. There's supposed to be a wrecker about 20 minutes down the road from
me, but I haven't ventured down there yet.

While I'm doing all this work, you're probably right that doing a flush
would be a reasonable idea. My only concern would be breaking loose a bunch
of crud that was nicely settled into place. :) No idea if that's a valid
concern or not, though.

Thanks for the input, guys.

Re: 88 Jeep Comanche cooling issues
 

I've had nothing but grief with Canadian Tire, and their local parts
department. I replaced my thermostat about a year ago, and I was in and out
of there at least 3 times trying to get the right part before I finally
yanked out the old one, took it in to them, and found out they didn't have a
matching one. Went down to the NAPA store, and was out of there in 5
minutes with the right one.

If nothing else, I've got selection. The local garage is a decent place in
a small town, so if he starts screwing people around, word will get out
quickly, I'm sure. Then the Canadian Tire is about 15 minutes away, with
the NAPA and a Parts Source (haven't checked them out yet) about 17 minutes
away. There's supposed to be a wrecker about 20 minutes down the road from
me, but I haven't ventured down there yet.

While I'm doing all this work, you're probably right that doing a flush
would be a reasonable idea. My only concern would be breaking loose a bunch
of crud that was nicely settled into place. :) No idea if that's a valid
concern or not, though.

Thanks for the input, guys.

Re: 88 Jeep Comanche cooling issues
 

I bought one a couple of months back from a local junkyard - they had
a whole bin of them - for about $30 and that included the cap. I got
the same story at the dealer you did - ouch! Until I found this
place, I was ready to make my own out of sheet copper with a regular
radiator cap and a sight glass I had laying around but I don't
recommend this unles you've done a bit of sheet work.

Before you try mending the bottle, remember that it IS under pressure
same as the radiator. Assuming 15 psi, it is really hard to get a
decent repair in that polyethelene bottle and that still leaves the
cap to fit. The last bottle I replaced had problems around the neck
on top and would not seal with a new cap.

That crack would account for most all the overheating - same as a bad
radiator cap.

Have you tried the mail order houses for a bottle? I've seen them
somewhere - surely sombody has a few sitting around.

Re: 88 Jeep Comanche cooling issues
 

I found a whack of them on eBay for $27 US ($30 Canadian), but nothing in
Canada. If anyone is aware of any mail order Jeep places in Canada, I'm all
ears (and eyes, I guess).
