Water pump and thermostat replacement. 2001 Jeep Grand Cherokee

[@SouthMiamiMartialArt]

What a great video! We're planning on doing my son's 2002 GC. This video is GOLD for that endeavor. Thanks again!

[@jointheir9594]

Nepa Krawlers, Just subscribed!!! The visuals were excellent, your teaching skills are on point!!! I am a woman and I would want you to teach me about trucks, cars!!! The best video I have ever seen on YT concerning my Jeep!!! Thanks for sharing your knowledge, I really appreciate the instructions on the thermostat!!! And the pulley, my water pump needs to be replaced, but there is a CLACKING noise that, I now realized after praying and asking others what it might be and my brother said, the water pump when its in need of replacing will make that noise!!! Thanks again, I must learn about torquing!!! I can do all the other things, but not confident about torquing just yet!!! My daughter probably can handle the torquing for she is good with the tools!!! Thanks again for great video!!!

[@dkenderdine79]

Thank you much appreciated.

[@pineapple7502]

Awesome video! All the details and pointers are what these videos need for the backyard mechanics. Well done sir!

Yo man today at 3 am my truck over heated. Stuck on the 105 west off ramp here in LA. This video just saved me some money 💰 🤑 . I'm waiting for the autozone to open up and I'm changing my waterpump thermostat and radiator.

[@jessec-q5589]

Really appreciate the attention to detail you gave in this video. It was very helpful. Thank you for taking the time for us.

[@tselinsky6452]

I just left the fan shroud in and did both thermostat and pump. No issues, just a bit tight. Used my normal ratchets. Great detail on bleeding the system!

[@brad300ZXS16]

I'm currently doing a water pump job on my '98. Be glad you don't have to mess with the power steering pump and tensioner bracket!

[@ibberman]

Some people insist the water pump bolts have to be coated to prevent leaking, even into the engine ? doesn't look like I should worry about that? Great instructions, thank you. 👍👍👍

[@ricdwe]

I have the same model Jeep Cherokee, in every way -- with the exact same problem and replacements, as you demonstrated. I kid you not. After searching KZbin for [how to videos], this was absolutely the best DIY video I've seen yet. Completely detailed in every way. Even down to video quality and sound clarity. You are someone to watch. I tapped the bell, to not miss your videos. Many thanks for presenting this video.

[@69fenderstratdan]

I had a hell of a time a couple years ago sealing up that damn verticle thermostat on my wife's Jeep. Just like you stated in the video that thermostat would move right before you seat the housing flush with the cylinder head. I'm going to try your method next time because 2 yrs. later (now) the S.O.B. is leaking again. Thanks for the video and the advice. I appriciate it sir.

[@davidmcmillan343]

excellent explainer on the 'burping' process! Keep 'em coming!

[@lawrencefalco3546]

Thank you immensely for saving me hundreds of dollars! The only hint would be to keep the lower radiator hose coil spring for the new one. I cleaned off the old spring and fed it through the newer one.

[@gregorywilson7858]

Great video, detailed (one long bolt in water pump) little things like that are important to the novice. thanks!

Thank you for the video. Excellent advice and you're camera work is very good as well as your mechanics. ;) Out there today doing same thing so your video will help me so thanks again.

[@dkenderdine79]

My camera work was pretty terrible but thanks! 😉

[@tonymadrigal2301]

Thank you for providing a excellently detailed video! My 2000 4.0 WJ is slightly different than the one you worked on in the video; I was completely thrown off when you pulled the fan shrowd off so easily only to discover there was no clutch style fan attached to the pulley. I honestly didn't know some WJs came that way. Do you have a video where you replace the water pump in a 4.0 with a regular clutch style fan attached to the pulley like my WJ? Or do you have any tips or tricks on the easiest/quickest way to replace the water pump with fan clutch? Any information will be greatly appreciated.

Excellent video, what brand water pump you use? mopar or other?

[@dogsarefun2]

Ready to do a thermostat and water pump replacement.... is it ok to use thermostat gasket and put the sealent on both sides of gasket?

[@nevarrekrivachek651]

its sad that you gave me better instructions then the people at the auto parts store thanks man

[@dkenderdine79]

Its not sad. They sell parts. I'm a certified master tech. Its actually quite understandable 😆

[@Whomadegod]

theyre not mechanics with 25 years experience its silly you would expect them to be

[@jonathanlopez7672]

I have a 2001 jeep grand Cherokee, could a fault water pump cause the car to shut down while driving and cause the coolant light to come on? Trying to determine the root cause before i throw start changing parts?

[@jointheir9594]

NEPA Krawlers, helloooo!!! As I watched the video to gather my tools together, I realized you did not show replacing the water hose pulley!!! Lollll!!! I thought perhaps I missed it and rewound a couple of times and then I saw you were reinstalling the fan and I said, I must have looked away and missed that step, but nooooo I did not!!! I rewound the video again and the pulley was on and the belt!!! And you were reinstalling the fan!!! O.k. Still very good video!!! Thanks again!!!

[@dkenderdine79]

Good catch! The shot must have been deleted in editing... But its pretty self explanatory.

[@jointheir9594]

@@dkenderdine79 All is well, still the video and all your effort are very much appreciated!!! I was being very attentive as a student who shall do the replacement for the very first time!!! Do I get a gold 🌟 for being very attentive and can I move to the front of the class??? Lollllll!!! Thanks again and please keep the video's coming!!! Bye for now!!!

Good video. Shows tip on getting four bolts off of water pump pulley. Thanks for sharing.

Did you had to change the timing chain?

[@darrellwilliams4520]

@Nepa Krawlers well this is just the video I needed to find because I too am now in this same boat, gotta replace the water pump in my '01 Grand Cherokee. Thanks for the boost of confidence with video. I need that red tools you used to fill the jeep up and burp the air out of her. Autozone? O'Reillly's? What's the tool called again?

[@dkenderdine79]

Cooling system funnel. I believe I got it from matco tools it's nice to have but not necessary

[@darrellwilliams4520]

@@dkenderdine79 yeah, O'Reilly's wanted $45 bucks for it, and like you said, a backyard wrencher like me only needed it one time. Maybe I'll get one later, but for now you're right, it wasn't necessary. They had another regular funnel for $1.79! Did the exact same thing, thank you for the excellent video! First time job for me and thanks to you I did it right! Temp guage now hovers below the 210 degree level. Bam! 👊🏾

[@dkenderdine79]

@@darrellwilliams4520 that sounds about what I paid for it, but it was worth it to me because I use it all the time for my job. Besides playing with Jeeps at home and making videos I'm a Master certified Technician for my day job 😉

[@YouTuber1g]

@@darrellwilliams4520 -- I made my own funnel. I attached a piece of PCV pipe to an empty water bottle with duct tape (cut the bottom off the water bottle and PVC attached to the bottle threads). Then wrapped duct tape around the end of the PVC pipe until it was the perfect circumference to fit into the radiator fill. Worked like a charm and let the car burp when I replaced my upper and lower radiator hoses

[@nebulousJames12345]

what is that piece attached to the water pump?

[@jonpatton7332]

Hi nice video, do you have a recommended parts brand for water pump and thermostat?

[@dkenderdine79]

OEM mopar is always best.

[@susu-mi7kx]

Hey I replaced the radiator... ( 2001 grand cherokee laredo 4.0 6 cyl) both lines were seized to busted up radiator so i disconnected them from the trans lines( skinny hoses) just I did not take note of where the top/bottom radiator trans cooling line connects back to. please help. does top radiator line connect with top skinny hose.?, on my jeep the trans line sit on top of one held in place by clip like a brake line then the skinny hose .. before one of the hoses (the bottom line) there is a check valve looking thing then the skinny hose, the other line the skinny hose just connects to the line. So would the upper radiator trans cooling oil line connect to that top line, or bottom. help a girl out please its been days...

Excellent instruction. Very detailed and very easy to follow and understand. I learned alot thanks for taking the time to do video man. . Cheers.

[@keithmorgan266]

Did you wait the 24 hour cure period with the ultra black on the thermostat housing? Didn't hear you mention how long you waited before introducing coolant.

[@dkenderdine79]

I've found if it's compressed you don't have to wait long for it to set up. Then with the engine heat it accelerates it. Been a mechanic for 26 years never had one leak

[@yaestalasopa5541]

Great vid... about to do the same to mine...one question tho didn't quite get the jacking part on bleeding rad...front or rear gets jacked ?!?!?!???thank you sir

You didn't show taking the clutch fan out

[@mayhewcastro1505]

Hi good video my 04 grand cherokee is over heating at idle i and the fan does not come on dont know what is wrong , the vehical does not have a fan relay ,

[@dkenderdine79]

There is a solid state fan control module mounted behind the passenger headlight. They are known to fail. It's a small black square with a heat sink bolted to the fender well just behind the headlight. If you remove the headlight it's easy to get to. Otherwise it's pretty impossible to see

[@revolutionday1]

Coolant temp sensor.

[@carlatrahan6693]

what is the name of the part that you remove with water pump in the vice?

[@Brian-qw2nj]

heater hose pipe

[@fatman5706]

If your jeep has Air in it it will over heat so How do I know if the water pump is shot or if I just have air in it?

[@dkenderdine79]

Water pumps can fail in 3 ways. A leak at the bearing (the weep hole on the underside of the pump shaft will drain coolant) or the bearing will fail. (Loud noise and wiggly pully) or the impeller can rot and disintegrate causing a low flow condition. A good way to test your pumps flow rate is to disconnect the heater hose coming from the water pump at the firewall connection. Place it into a bucket and start the engine. If coolant pumps out rapidly the pump is working. If it doesnt pump out or is very slow the impeller is likely damaged. If your system has been closed for some time and they are no leaks its safe to assume the air has purged on its on (its designed to) you only need to purge it yourself when the system has been drained as in this video. Also note that your overheating can be caused by many factors including a bad fan relay, bad fan, bad head gasket or cracked head. If you can verify the fan works, and no coolant is being lost. Check the flow of the pump. If the flow is good assume the theromost is failed.

[@leeatterberry1453]

👍

[@allenballard2681]

Great video, but where's the fan & fan clutch. Most of the videos this is gone. Also I've looked at used Jeeps with I6's & V8 but no fan or clutch. My electric fan is toast and I took it off 12 months ago. Most aftermarkets are too deep and hit on the stock fan/clutch. Only one that fits is AutoZone's. Lastly you didn't mention the thermostat bleeder valve goes up as positioned in the block.

[@dkenderdine79]

This is an 01 grand Cherokee only 1 multi speed E fan. No fan clutch. The factory thermostat does not have a bleed valve. Therefore I didn't mention it because it doesn't have one 😉

[@ricdwe]

@@dkenderdine79 you good dude. You know your stuff.

[@Alfonso-nc6lw]

Thanks men. nace video

[@johnbrummet524]

been a mopar fan all my life And always only owned a mopar. worked on em whatever repair was needed. In 2019 i bought my 1st Ford. A mustang GT. Modded the car like you wouldnt believe. Im here to tell ya...Ford engineers are smarter than mopar engineers. Fords can be built quicker on the line. And fixed faster by the end user. As a born and bred mopar fan...after owning my 1st Ford...gotta say...mopars suc to work on , compared.

[@CameronDC-Grimes]

I actually agree, there are some very dumb Chrysler/Mopar engineering designs. If you have the 01-04 WJ 4.7L you know what retardation went into radiator removal design and the OE fan module being under the passenger headlight under a plastic layer you need to cut a 4" square into just to get into it and let airflow in. The failing door harness wiring is cheap wires that are 5 different gauges. The proprietary bolt sizes on sway bar link to bar. The hydrolic fan instead of a electric fan. The shroud eats up all the space and honestly not needed, no overheating here and I don't have mech fan just a 1350CFM 14" fan.

[@spicecrop]

That year cherokee is not supposed to use the green antifreeze. It's supposed to have the red.

[@dkenderdine79]

The color means very little as long as it's compliant with Chrysler specifications for that year which most antifreeze is now. The red coolant it's just extended life that's the only difference
