Thank god for this video! The dealer was trying to charge me $2200. Said it was gonna be 4 1/2 hours of labor and the part was $900 🫤

[@abeltorres6563]

I give these men a standing ovation, a 10 out of 10, I’m buying my self a kw T680 MX13 , and these men give me hope. Well done y’all!

[@Redbikemaster]

This channel is a gold mine if you own an MX13

[@KoonTrucking]

Thank you

[@edjahman]

I changed the water pump and the bottom hose on the radiator and those 3 plastic fittings that the heater hoses are connected to on Saturday. The water pump was very easy and I couldn't have done it without your video. Thank you so much. I appreciate all of you at Koon.

[@KoonTrucking]

Glad you got it taken care of and saved a bunch of money doing it! Job well done !

[@AL-Boogie.]

You're right it's easier than the detroit no gears to deal with it enough space to work on etc best part wild Billy using KY he seem to have practice with it 👍👍i really appreciate it guys

Thank you

[@jekylljr-trucker7238]

Thanks for the videos ! I’ll be doing my own on a 17 mx13

[@terrystoner4504]

Seems like that cooling system is easy to get the air bubbles out of. Worked on a couple Freightshakers and they both wouldn't pop their cherries unless you took them down the road a piece, became more of a job than the repairs. Good vid guys!

[@KoonTrucking]

Terry Stoner they actually are easy to do a waterpump job and get the air out. Probably the easiest ones there is

[@HerreraCam]

I'm about to get into tractor trailer maintenance. Thanks for this, guys.

[@mcombuster]

I swapped an mp7 starter in 1 hour. No exaggeration. Paccar starter is definitely a 2 hour job at best I would be impressed to see someone do that in 2 hours.

[@robotvacuum1957]

Very easy pump to change. Before this I thought Detroit series 60 was the easiest. They both are a hell of a lot easier than a 3406 cat and definitely a cummins, especially the old NTC Cummins.

[@henrychavez8068]

One of the best how to videos I've seen. Informative and to the point. Thank you

[@KoonTrucking]

Thank you!

[@feeneysmechanical6215]

Nice work guy's, what I have done is find some of the same water pump bolts. Cut the heads off the bolts. Then cut a groove with a die grinder say a 1/8 of inch. Just enough to get a stubby flat bed screwdriver to thread them in the holes of the block to use them as alignment studs. I slip on the new pump on the studs and take one stud at a time use the original bolts to reinstall the pump and this way you don't have to fight getting it mounted up.

[@KoonTrucking]

Greg Feeney that’s a good idea. Usually we will hit it first try but this was a stubborn one.

[@HarryC786]

As usual, Always amazing 👏 . You guys the reason I bought paccar. Please keep coming the awesome information.

[@dannyjones3840]

Great video, my 17 T680 is leaking at only 343k, looks like an easy do it yourself at the truck stop job lol.

[@freebir73]

THANK YOU SIR YOU HAVE HELPED ME ALOT WITH YOUR VIDEOS.

[@walt404]

Thanks for your video ,it was very informative 👍🏿 and save me money 💰 🤑 💸 👍🏿

[@Toolaholic7]

Grease works well on that type of gasket too.It is cheaper to fix a leak than ignore them burning up an expensive engine.I have seen engines burned up all because of leaks ignored

[@mcombuster]

I work on garbage trucks. That engine is a good over the road truck but from my experience most guys including me struggle with repairs on those truck. Discharge line for instance a common issue is bracketed down to top of Trans and connects to a metal pipe that wraps around and bolts down to top of air compressor. Depends on truck it's either under body or under cab, have fun getting them off when they clog up and truck won't build air pressure. I'm 140 lbs skinny as .... so I can get of quick and easy but most guys are tiny and can't fit. Garbage truck front loads usually have a service lift to raise the body which makes it super easy, if the lift isn't trashed which they almost always are.

[@edjahman]

I'm going to attempt a water pump replacement tomorrow. Ty for the information. I feel pretty confident because of you guys. I'm also going to attempt to replace the plastic fittings that go into the block where the heater hoses plug into. Have you guys messed with those? Ty

[@dieseldoctor9294]

Gravy as long as u can get to the tensioner to release it! Good video as always sir!

[@djzippy312]

I'd love to see a video of you replacing the thermostats on an MX13

[@zionjuba4779]

Great videos...I have a Paccar MX 13 as well KW T660. Thanks for all the information you share.

[@KoonTrucking]

Be sure to check out our playlist diy truck fixing. Lots of paccar stuff in there.

[@Zak6959]

I was going to mention a cool: tool called a coolant lift pump, it’s great for checking your coolant system with a vacuum before you have to refill the system, also you can actually refill the system with the tool instead of putting in the jugs or putting in the original coolant. Google it or KZbin it, it’s a pretty neat tool. Helps avoid airlocks.

[@KoonTrucking]

I actually bought one after this video

[@scottpearsontoolsmore185]

if only every job was that easy! looks like a nice relaxing day at the shop.....for bill! was that an "M" word ratchet i saw there....it must be bill's!

[@KoonTrucking]

J.C. SMITH PROJECTS haha it was Bill’s there’s nothing in my boxes that has the M word stamped on them

[@j.c.smithprojects]

i am happy to say that there is no mac, matco or cornwell in my box now. it is a shame that a bad dealer can make you dislike the brand name.

[@KoonTrucking]

J.C. SMITH PROJECTS yeah I have 90% Snap On and a few Cornwell but luckily for me I have a good dealer so ...... but no more M Words at all !!

Great video koon trucking thanks for the great teardown

[@sneakysnake109]

Did wild Bill use his tools out just grab some of Wally's that were still laying on the floor?

[@sebastiancannavo8786]

That was easy. Truck looks kinda new or very clean.

[@KoonTrucking]

Sebastian Cannavo it’s actually 3 years old now. Needs a bath ! I like for our trucks to stay CLEAN! Thanks for watching and taking the time to comment !

[@the_traveling_man4284]

Can I pull this off with standard ratchets or do I need those specific lengths?

[@KoonTrucking]

No you can use anything even wrenches. This just makes it easier

[@nicholaswilson2134]

There is a nut that has part of cut that is leaking that on the part that the filter screws into that is leaking is it just the bolt that needs to be replaced

[@mikes8189]

What is the part number for the water pump? Appreciate all the videos you post helps me out.

[@craigthomas4999]

Why couldn't cat made them so easy lol. 60 series are easy if you don't have to fight the frame . Nice job and good video as always

[@KoonTrucking]

Craig Thomas haha ! I know I just thought the 60 series was easy until the Paccar came out ! I don’t mind them at all !

[@Danogstunter]

What’s the part number and where did you purchase the pump from?

[@mcombuster]

Then when your air compressor goes have fun getting those inside mounting bolts off of the starter and air compressor. You also have to pull the fuel pump it's mounted on front of starter. There's a lot that can wrong there to. The air compressor has a oil tube thing I don't remember what it's called but it goes in side ways thru the compressor into the engine and to get an Allen head on it in between the compressor and frame is horrible it's a real tight spot. I watched 3 mechanics combined 30 years xp break that compressor off the truck because of that stem. Then the truck sat for a week while they tried to figure out how to get that stem. It's always a Paccar, waiting for parts. Mack, bam they are there that day or next day. That's my experience with them. They are good over the road trucks, but horrible garbage trucks. We have one that stalls out sometimes twice a day and rush has "fixed" it like 6 times for the same thing it will go out the very next day and do the same thing after they "fix" it, I'm not exaggerating. Rush is a Peterbuilt certified dealer if I'm correct, all the Pete's we get have paccar mx13 or whatever they. I had one I did a pm and oil change on 2 years ago. Cabbed it over and the cab cylinders took a sheet and it wouldn't cab back over then after oil change it wouldn't start and nobody could figure it they had to call rush. It sat in a bay for week broke the phuck down and it's a defect with the fuel filter it would do it sometimes after a filter change. I can't remember but it sucked bad. Flooded the bay with dookie juice and sat for a week like that.

[@prevost8686]

Leaking out of the weep hole.... Getting old sucks.

[@AvtarSingh-ki5my]

Do you guys have videos on emission parts replacement? specially diagnosing

[@Wytchdoctor77]

Can you guys do a video on replacing the power steering pump on a Paccar?

[@SIKKMAD3]

Tnx a lot for this video 👍

[@mikerussell4859]

I cant get the five bolts too line up got 3 in 2 wont line up any suggestions i dont wanna cross thead them

[@mcombuster]

But they are good over the road they seem to break down less than an mp7 or autocar but they can be horrible to work on. The new ones like the engine in video don't have that fuel filter anymore. I haven't seen the new new ones we have a bunch of 2019 paccars and we have a couple front load Pete's around that have a Cummins in them I don't what the engine is called I just fix it lol. It's red

[@heavydutyrepair64]

The mack mp7&8 is easier I believe

[@mafhu9027]

I have Kenworth T680 2015, engine oil overflow the power steering reservoir Do you know the solution? 😬😬CAN U HELP ME? Thx

[@DLSWV]

I hear gots say you have to take the mx to a pacarr shop only they can work on them. And for general repairs and maintenance parts can be hard to locate. ?

[@KoonTrucking]

Lots of paccar is just rebranded cummins

[@redmesa2975]

I’m curious about how to change the air compressor. Paccar has it tucked into the frame rail, at the bell housing. Looks like a pain to get out ! Is it secured to the block by a large snap ring, because I see no fasters ?

[@muthatrucka76]

Do y'all do any maintenance for outside companies? Gotta 2015 579 MX13...Would like for you guys to look her over...Based out of Oxford MS..

[@KoonTrucking]

Yes

[@stariontransport7991]

Would that be the same procedure on a 2018 model. Since the water pump is a little bit different. Just wondering if they added a bleeder somewhere to get the air out

[@draconis0469]

Is there a way to change the pump without draining all the coolant?

[@johnrusselllubo]

My coolant temp sticks at 165F, Warm but not warm enough Can tell somethings is forcing the Thermostat to run at Cooling mode. Truck runs fine no check emgine light but its annoying when your cruising on the rolling hills when its time to get a hard pull engine is Luke warm. I thinking it may be my coolant temp sensor or thermostat. I have a 2015MX13 500/1850 mounted on a long nose pete. Could this just be the Ambient temp in that bay because its has all the room in there to fit another mx13 and big grill sucking in cold air? 🤣 Your advise will be greatly appreciated and will save me time before I even think about pulling parts here and there. 😇

[@AvtarSingh-ki5my]

Please put at what mileage yo change parts and how much they cost thanks.

[@kelvinmiller7016]

What's the part number on that water pump

[@danielricketts6469]

how to change the thermostat in paccar mx 13 please?

[@shawnnagreenhill8539]

[@scottwirth783]

I got all the way to pulling out the water pump, and couldn't get it pass the fan blades, only needed half inch but couldn't get it out so ended up putting it back together with it still leaking, T-700 Kenworth, wasted day.

[@Wytchdoctor77]

I had the same problem on my T700. What I ended up doing was using a Milwaukee rotary tool to grind out a gap on one of the fan blades, big enough to allow the pump to clear. Took about 5 minutes.

[@eagletran9]

Thank you sir

Have you found the 15's are running with less issues then the 12's did ? Don't hear much on the newer MX13. But sure did hear lots of them the first few years. Still like my old Series 60 Detroit. Also it was coming a flood in Selmer Tn yesterday also.

[@KoonTrucking]

Pete k they have less issues but we have learned some tricks on them so we love em

[@Pete-from-Tn]

Thanks may have to come by the shop. And talk to you soon. May be looking at a TRi Axle or Quad dump truck. And finding the trucks with that engine. Weights less for sure, and less weigh means more $$ at the end of the day.

Looks like you guys didn't reverse suction the coolant in, I've got an 2016 t680 paccar mx13 and am about to change my water and coolant. The cat guys are telling me to reverse suction it, but if I don't need to I'd rather not. Will the engine be fine if I just dump in the coolant and fill as needed?

[@KoonTrucking]

You seen us do it.... that’s all I can say. It’s your truck and your call on how you do the repair. We just show it the way we do it. We have done it with vacuum and without.

[@KoonTrucking]

They are pretty salty i think around $150ish ?? Don’t quote me on it but they are high. Easy to change not tools required. Just pop the connector loose and pull it out and pop the new one in. Coolant doesn’t even come out.

[@KoonTrucking]

Not every person on KZbin is my customer and most guys that will try to do a water pump won’t use KZbin (I mean at the end of the day it is a water pump) and most guys that will pay to have it done at a shop wouldn’t get their hands dirty in the first place
