SOURCE: just replaced the water pump,

Check to see if the thermostat is installed correctly there is a certain way it goes the cooling system. Since you have had a lot of parts replaced could have air trapped in system this can cause overheating as well. Drain radiator leave cap of and start motor add water slowly until radiator is at the level recommended. Does car have white smoke comming out exhuast pipe this would be good indication of a blown head gasket. Hope this helps

SOURCE: drain radiator

How easy is it to remove lower rad hose? I've reverted to that more than once rather than fight with some of those drain plugs & their neat locations.

SOURCE: 1990 4.2 Jeep Wrangler that is overheating

Still sounds like a bad or from scrapyard? If you can't add coolant faster than a really slow dribble that's a big clue.
You can run the engine with the heater on high and the engine should not air-lock. I'd also remove the thermostat just to make sure it is not defective. Run the engine without it and see if it still overheats. Last, it is possible that your head gasket has failed, and engine compression is causing the overheat. I tend to think not only because the hose stays soft.
While it's running, also make sure that the lower hose is not "sucking in" if it is, replace it. On 4.0 engines you can also get the serpentine belt on wrong and it will drive the pump backwards. if you replaced the belt check that too.

SOURCE: My 2002 Jeep Liberty 3.7 liter is leaking coolant

The Drain Plug aka Radiator Drain **** has an o-ring on it that does wear-out over time, causing a leak. You can remove and replace these relatively ease. They only turn 1/4th to 1/3rd Counterclockwise to Open and Clockwise to Close. Work on only when the engine is cool. Leave the cap on the radiator to create a suction, decreasing the amount of radiator fluid you will lose. OR drain the Radiator Fluid into a clean container and save for reuse.
Have the new Radiator Drain **** ready for immediately insertion after removing the other leaking Radiator Drain ****. To Remove:
Twist the Radiator Drain **** counterclockwise and pull, continuing to twist counterclockwise removing it.
Immediately install the new Radiator Drain **** by first pushing in and then twisting clockwise to close.
Let me know if this helped, or if you have additional information or questions. Feel free to contact me at!

Replaced radiator and tstat still over heating, water pump a little over a month old

my used 4 cyl jeep radiator would only drain 1/2 of the fluid. jumped up and down on bumper and this dislodged the sludge in radiator and/or engine. flushed twice, then now notice low temp reading on gauge (out of specs) due to a low temp thermostat that someone installed due to previous over heating (sludge). Replace with factor spec thermostat and everything is fine.

Do I need a special wrench to remove the radiator bracket on a 2001 Jeep Wrangler?

You may have torx head screws there, like on a '95 cherokee: size t-30 for the radiator bracket, and oddly enough, the hood latch piece there was also torx head, but sized t-27.

Where is the radiator drain plug on a jeep cherokee sport 2001

On some you need to remove the front grille. on others you will find a access square on the passenger side of the grille. The drain itself is on the front of the passenger side radiator tank.
I've found that most of the drains don't work properly and that if you remove the air filter box (two 13mm bolts in the bottom of it) it gives you easy access to the lower hose. Much faster and easier to drain from there by removing the hose from the radiator.

Changing the thermastat 2001 jeep grand cherokee


As in most designs, the radiator drain plug would be at the lowest part of the radiator. However, in some instances, it would not be readily accessible due to some other components such as a skid plate, fan cover brackets and others. An alternative is to loosen the lower radiator hose (radiator end) which should serve the same purpose.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information. Good luck and kind regards. Thank you for using FixYa.
