Still unexplained Coolant loss
My 2001 Jeep Cherokee has a total of 29.5K miles with only 5 weeks
to go on the warranty. I have taken the XJ back for a 2nd time(this year)
now for coolant loss. There are no traces on the ground or in the engine
compartment. I do not see excessive smoke out the tailpipe or any wetness on
the hoses or smell it anytime .The bottle was checked by the dealer and
found nothing wrong with it or the system. Both times the dealer had
pressure checked the system to 18 psi and left it sit for 40+ minutes with
no pressure loss. I have asked as of this week that THEY will add coolant
when I see the bottle go empty. This is my attempt at as much documentation
before warranty expires. The consumption rate in the last 3 months or
approximately 3000 miles was 2 gallons!.
Anyone with similar? How was it resolved?

Cracked overflow hose or leak at the overflow hose connection on the
radiator. Another possiblity is a slow leak by the water pump shaft.
Those can produce just a few drips at speed and are difficult to find.
I'd hang my hat on the overflow system.

Re: Still unexplained Coolant loss
Hey Doug,
Dealer checked the bottle and hose and found nothing. I have had water pumps
bad before on other vehicles, usually some noise from bad bearings or a
wetness on the engine. None of these symptoms.

I had the same thing happen to me on my Ram, replaced the thermostat and
radiator cap. The thermostat was sticking and when it let go it forced the
water by the cap and when I stopped the vacuum sucked the water out of the
reservoir leaving it dry. No problems now.
