If you are trying to solve an overheating problem this will not achieve anything, but if just to clean out dirty coolant this is how its done..
When engine is cold !!! with radiator in vehicle.
1/ Remove Top and bottom radiator hoses.
2/ Insert garden hose into bottom hose connection of radiator (Use a rag to help seal the connection) turn on water fully to reverse flush radiator till water comes out of top connection, repeat a couple of times.
3/ Reconnect hose to radiator , fill with clean water only.
4/ Run engine till it reaches normal temperature, then switch off engine and allow to cool.
5/ Remove bottom hose to drain system again, refit hose and refill with a good coolant mixture according to you climate.

1997 jeep wrangler overheating


bought a used 97 jeep that apparently had the same problem and had a low temp thermostat installed in attempt to cure the problem. I noticed when draining the radiator that only 1/2 of fluid came out. I jumped up/down on bumper and dislodged sludge and other half of fluid. Flushed system twice and then noticed temp gauge was now registering low, out of specs. Placed in correct thermostat and all problems solved.

Jeep Overheating?


I would suggest you have the radiator and cooling system pressure tested . .another option would be to get a new radiator cap and try that. If you want to do a quick test for the radiator cap .. try loosening it to the first notch and see if your overheating problem subsides ..

No Heat 1988 Jeep wrangler


any time you do not have hot water in the hoses to the in side of the vehicle, your water has quit either due to you having only water in the system and it froze in the winter and you started it . or the propeller just broke of old age. make sure u dont have a check valve in the hoses going to the heater core in side the car. valve would be under the hood somewhere in the duration of one of the two hoses, which is the feed. this should do u good

Radiator problem, I think?


Not likely, but you can flush the entire system, and that would give you an indicator of the condition the engine is in internally. Smell the overflowing coolant, if it has a burned or exhaust like smell, you need to look at your engine gaskets.(Cyl Head gasket) especially. in a worse case scenerio, the heads themselves may need to be looked at. When you get a cracked head, you typically get a condition where the pressure the engine makes, pushes to coolant back through the system end up in the overflow bottle. I love jeeps, so good luck with this repair.
