Hi all,

Just picked up a 93 jeep cherokee sport for a few hundred dollars.
Everything was great until tonight, when upon parking I noticed the car
was losing a lot of coolant when I parked...basically pouring. I
managed to get the car home, there was no over heating indicated by the
gauges, and park it. The car was driving fine the 2 miles it took to
get home (just smoking from the coolant). I looked for a leak but
couldn't identify one in the radiator or the lines. How could I
identify if it was the water pump that has gone? Does anyone know of a
engine diagram online?

Thanks for your help!

Best,
Breton

ps. Separate problem. I is very difficult to get into second gear when
cold. Any ideas?

There is a 'weep hole' on the bottom of the water pump. Look for rusty
stains that look like it may have been leaking from there. It starts as
a daily drip and then ultimately, a gulley washer.

You can look around my site. But no, no online manuals. I'd suggest
getting the service book if your going to do your own work.

Refill the radiator, dry off the engine and hoses, then start it up
and watch for leaks. That's about the only way to do it unless you
have a pressure cap.

I had an issue with the radiator cap being loose. The metal ears
that hold it down were slightly bent down out so I just bent them
back a bit with a pair of vice grips. Leave the ramp so you can
put the cap back on.

Leaks can happen almost any place, but running coolant is usually
a hose. The heater core hose was the first to go on mine.

The problem with using the temperature gauge is it reads from the
pump output. No water = no reading. At two miles you should be
fine but in the future, it's better to fill the radiator
with water and leave the cap off when you drive home. You leave
the cap off so the coolant can still circulate but not build pressure
and leak. The trade off is it will boil when it gets too hot.

A leaking pump will run down the face of the motor. Just make sure
it's the pump and not the lower return hose.

Also, if it still has the pressure clamps, when you put new hoses
on, use the band style. The old clamps loose their effectiveness
over time.

Automatic or standard transmission?
For automatic: Check the transmission fluid level.
Engine warm and running, transmission in Neutral.
(remember to apply the parking brake)
