2006 Chrysler 300C 5 7L Hemi Water Pump R & R

This is a "How To" video for removing and replacing a Water Pump on a 2006 Chrysler 300C with a 5.7L Hemi engine. It is a fairly easy project - yet, there are a few little details that can make a huge difference on your success or failure. Please pay attention to details while working on this project - especially when removing the metal "bypass" tube - making sure that you do not damage it. If you have any questions, comments, and/or helpful hints, please leave a message in the Comments section.

Thanks gasket tips personally helped me

[@mliphart]

Thanks for the comments.

[@michaelm_713]

Thank you for this video sir. My son’s water pump in going out on his Charger and this definitely helps me out a lot.

[@mliphart]

Thanks, that's why I do the videos. I appreciate the comment.

[@smokeyj3983]

How do you know if it's going out. Looks like mine is starting to leak, I didn't know if it just needed a new gasket or the whole thing.

[@mliphart]

@@smokeyj3983 if it is starting to leak, then it needs to be replaced.

I have another question. My r radiator hose came loose while driving my vehicle. I didn't notice at the time that it was leaking and my arm check engine light came on so I turned my vehicle off then turned it back on tried to turn it back on but it wouldn't start but the radiator holds back on and my car's been having issues ever since because of that radiator hose coming off cuz that had something to do with my water pump malfunctioning?

[@mliphart]

It is possible that there is air in the system - providing that the water pump isn't leaking. I have found that with some vehicles - including this one - that after you fill it with water, you have to run the car for about 20 minutes with the radiator cap off - refilling as necessary - to get all of the air out of the system. If there is air in the system, the car will overheat.

[@zzxenu]

i can use black adhesive sealant silicone rtv for this right?

[@mliphart]

Yes, you can.

[@crazylarryjr]

Is there a torque spec for the bolts? Or is it a more snug to a little grunt to tighten? thanks for the vid, great vid

[@mliphart]

I'm sure there is a torque spec S but, I just snug them, and go around a second time to make sure I didn't miss any.

[@crazylarryjr]

@@mliphart, That's what i figured thanks, This looks easier than the water pump i did for my Dodge Dakota V8 years ago

[@chrisw7542]

Good information

Thanks,

@@mliphart my friend has a 2011 300 and it's over heating and the motor chugs to a stop at every red light and stop sign. She had the thermostat and hoses replaced. I think it's the water pump. And I hope the chugging is just a dirty throttle body. Any thoughts?

[@mliphart]

@@chrisw7542 I'm not sure what you mean by "chugging" - but, if it's what I think it is - it could be caused by the engine being too hot. Other than that, I'm not sure - without seeing it. The water pump may be the issue with the overheating problem - fortunately, it is a fairly easy project.

[@freddiethorpe879]

Thanks I have to do 1 today

[@mliphart]

Let me know how it goes.

[@19kcartio31]

How did it work out ?

[@nicholas440]

Did you drain any coolant before?

[@mliphart]

Yes, you will need to drain some of the coolant.

[@ya_native1734]

How did you take the old idle pulls off and put it on the new one?

[@mliphart]

I'm not sure what you are referring to, can you be more specific?

[@ya_native1734]

@@mliphart nvm I figured it out

[@JeffreyMillswa6cej]

Should there be an interest for preventative maintenance concerns, my 06 300c had a water pump leak at 100K miles and it was 18 years old at that time. I heard of one being replaced at 16 years old with 190,000 on it.

[@mliphart]

No, this is one of those repairs that you will typically only do when needed - or if you have to disassemble the front of the engine for something else - then I would replace the water pump.

[@JeffreyMillswa6cej]

@@mliphart 2003 through 2009 Hemi motors can drop valve seats particularly if the engine has overheated generally due to leaking radiator as these cars now are almost 20 years old. Replace the plastic fans (blades) as they become brittle as they age, suddenly break, then go through the radiator. A car this old should get a new radiator as well. If you have the single fan setup check fan motor bearings. Look for the heater hose near the fire wall with a “Tee” fitting that goes to the water bottle, those crack over time and leak. Good to replace the Tstat with a 180 degree and if you can get a tuner to make the fans come on at a lower temperature. If you have one of these it’s best to fix it before it breaks as the “Hemi” is expensive to fix.

[@mliphart]

@@JeffreyMillswa6cej thanks for the information - it is good to know.

[@JeffreyMillswa6cej]

@@mliphart one more thing. The transmission in this car is a Mercedes unit and is very strong. However, learn about the conductor plate in the valve body, and the pink thingy in the shifter. Also Chang the starter relay. If the AC quits, change the replaceable valves in the AC service ports.

[@mliphart]

@@JeffreyMillswa6cej yes, I knew that the transmission was a Mercedes - I didn't know about the other things. Our 300 has 180,000 miles on it - with not many issues. Thanks for your imput.

[@ezetymer6268]

Whats the pipe called that connects the the water pump in 2:52 called and where does it lead to.....

[@felipeavila4873]

Is there Part# for this o-ring or did you just use silicone

[@anthonyportugal9013]

How much coolant it takes to fill it up after replacing pump?

[@mliphart]

The entire system takes about 14 quarts - but, the system isn't completely empty. I typically will put 1 gallon of the "concentrated" Anti-freeze, and the rest water. Depending on where you live, and how cold it gets - you want about a 50/50 mix.

[@Malik-mx8st]

What kind of coolant did you use?

[@mliphart]

I always buy the coolant that says "mixes with all coolant types." That way I don't have to be concerned about what type is in there.

Hey Matt best to replace 2006 chysler 300c hemi water pump with an OE or aftermarket ok?, Purchased an aftermarket but can return and get stock, dont want issue in the future?

[@mliphart]

I used an aftermarket - no problems. On Chrysler products, I go OEM on electrical parts - aftermarket on most other things.

[@ufcplanet711]

@@mliphart thank you

[@ufcplanet711]

@Matthew Liphart my indications are no heat right away but it will come intermittent, also the temp has fluctuated weirdly, and when im driving usually on gas get the weirdest noise from the car grinding sound almost

[@mliphart]

@@ufcplanet711 my pleasure

[@mliphart]

@@ufcplanet711 I would start by removing the belt, and checking the pulley on the water pump. If the bearing is going out of the water pump, it could bring some of those symptoms that you described.

[@user-jn8vx7gu3j]

The bleeder screw on the front of mine is bone dry I hear a squeal when I cold start I’m guessing water pump being that it’s dry but what could be causing the pump to not get coolant in that area because the hose and rad have fluid in them but nothing in the front of the water pump housing, I’ve been having issues with it getting hot the. Cooling down getting hot then cooling Down originally had a leak and used k seal fixed the leak I think but then the overheating issues started, hasn’t overheated but it gets hotter than it’s supposed to I think I’ve seen it get up to as high as 242 then shoot back down to 195-197

[@mliphart]

These engines are very finicky. They get air trapped in them and will overheat until it is out. I start with plenty of water and Anti-Freeze, and with the reservoir cap off - start the car and let it idle - with the heater on high. At some point, the car will suck the water down - be prepared to refill it as it goes down - DON'T WAIT UNTIL IT ADDS MORE AIR INTO THE SYSTEM. I let this process go for about 45 minutes. It will bubble out both air and water - but keep it as full as you can. As long as you don't let air back into the system, you will be ok. I just had to do this to my wife's car. It got low enough on coolant that it got air into the system. It is an idiosyncrasy of some vehicles - this being one of them.

[@makantahi3731]

has this water pump tendency to wear impeller vanes and because of that to pump coolant to slow

[@mliphart]

I'm not aware of anything like that - but it is possible.

[@makantahi3731]

@@mliphart why am i asking it: i replaced both cooling radiators, good coolant , fans are adjusted to start to cool at 96deg C , thermostat opens at 88 deg C, and engine reaches temp 98-102 deg C in drive , at 180-200km/h at outside temp 30deg C, so only thing that maybe is wrong is water pump , that has worn vanes, i could replace it but if is not worn it is useless work

[@mliphart]

@@makantahi3731 yes, unfortunately, you don't know that until you remove it.

[@krystalrainer9722]

I put a new pump in but is is still overheating and now my heat is not working whatbdonjndo

[@mliphart]

With my 300, I have to let it run for about 20 minutes with the radiator cap off to purge all of the air out of the system. Also, it could be a stuck thermostat - did you replace it when you had it apart?

[@bozodaclown5425]

How do you add antifreeze

[@mliphart]

The anti-freeze goes into the reservoir - above the drivers side fender.. There is is no "radiator cap" - the reservoir is part of the pressurized system.

[@jaysmith5084]

Great video but you didn't plug in the air temperature sensor if you haven't noticed the check engine light yet .

[@mliphart]

Yes, I did later. Thanks.

I own a 2006 300c dang thing is just one issue after another first the mds went out, then the ecm went out got that replaced and on my way to work the water pump went out dumping coolant from the pilot, I’m just gonna avoid older models for now on I mean it is a Chrysler

[@leoncrisp5429]

I think my Chrysler 300 needs a water pump. What is the best way to determine if that's the issue without going to a mechanic?

[@mliphart]

Usually the best way to know if it's the water pump is to check if it is leaking water. There is typically a "weep hole" on the bottom side of the pump that starts to leak water. Are you leaking water?

[@mliphart]

I hear. I think mine has been pretty good. We bought it with 125,000 miles, and now it has around 188,000 miles - and other than the computer failure - most of the repairs on their car has been due to the amount of miles on it.
