Re: 2000 Jeep Grand Cherokee Limited
No, what you're seeing is the weep hole leaking on the water pump. This is the warning sign that the water pump is worn out. Don't use any stop leak or anything to attempt to stop it. You'll be waisting your time. You'll have to replace water pump at this point.

remove stat housing HOSE,. then the housing.
new gasket , sealant
wax side to water jackets side.
bleed hole up hill (aka. jiggle pin) same deal.
With the engine turned off, put your finger up behind under the pump pulley. if you find antifreeze there likely the pump seal has failed. Otherwise, locate the leak source and make whatever repair is necessary. You will get a noise any time water or coolant gets on the drive belt. Best to look before going through a pump replacement to find later you have a pin hole in the radiator on a hose!!!
check for blockages in the piping, this may be blocking the flow of the antifreeze.
Also check the coolant you are using it needs to be a 50-50 ratio of coolant and water in most cases. Please go by the manual.
is fan acually working? check and make sure its working. if not its the fan module located behind passenger head light. you have to cut a hole in body under headlight to access it. the hole will be covered by headlight so dont worry about making hole.
Front drivers side could be a bad cap, lower hose or the radiator itself. You need to look carefully and find the leak source. Steam travels and isn't a good indication of where the actual leak is coolant will run down and take any path it can to reach the ground. Therefore, you need to follow it back to where it is coming from, then deal with it. Your water pump can also leak and run down the lower hose. there is a small hole in the pump behind the pulley. If you see coolant coming from there the pump needs to be replaced. Sealers will not work on hoses or pump leaks so don't bother using them for that. Good luck...don't forget this is free, so rate answers! I will answer follow-up questions too!
