Water Pump Replacement Recommendations?


Recommended Posts

I need to replace the water pump on my 2019 Dodge Journey SE 2.4L, and I know a lot of people here say to get the parts from Rock Auto but which one do I get? They seem to have a few different brands, they also have with and w/o housing. Any recommendations would be great.

I assume it's knocking and leaking. For my wife's 3.6 journey I used the gates brand, it has a lifetime warranty, no housing option. But I bought the oem dealer gasket, its an unusual 30 thou thick aluminum material design. Even though gates came with its own gasket. A lot of labour on the V6 engine, didn't want to waste time doing it twice.

 

I try to use recognizable oem manufacturers like Gates, Dayco, GMB and if I can afford it dealer parts which are the best option in most cases. They even give good discounts if ordered at Mopar Canada online and picked up at a dealer, where I am.  Dealer parts are meant to last beyond a decent warranty period, so you do pay a bit more. You might see Mexico or China on the bags...but it is made to Stellantis quality specs.

 

What is interesting is the pump with housing and pulley deals are cheaper than just a pump flange unit no pulley. Logically the extra 2 pounds of steel and gaskets would cost more money. But getting the heavier assembly could bump up shipping costs. 

 

It's a bit more work changing the whole pump and housing, but you are replacing several extra original gaskets that are 5 yrs old. With time they can wear out. You are also getting a machined pump assembly, flanges are going to be matched/true from machining.  My daughter in law has a 2.4 journey, I'm planing on changing the whole assembly if extra  shipping is minimal.

The interesting thing is that there is no knock or leak happening, nor is there any chocolate milk in the oil or etc. But for some reason my vehicle's coolant level keeps going down (using 50/50) at the radiator only. It appears to not pull coolant from the reservoir either, I checked all coolant tubes, radiator cap (replaced), thermostat (replaced), and right before my warranty expired the shop replaced the water inlet housing, and that seemed to fix it but after a month or two, it started again. The vehicle is getting hot when in drive but when stopped at a light or stop sign for a period of time. 

 

The only thing I can think of after a few diagnostics are the fan or the water pump. Any suggestions?

Which is it? "Getting hot in drive or sitting while running" or both?

Coolant does not draw down or up much at all in the reservoir tank on these.

First thing is to make sure the radiator fan is working. It should come on at 210 - 214 degrees on the small info screen for the low speed fan portion and 230* for high speed(failsafe) mode. A common failure is the radiator fan resistor, mounted high next to the fan opening on the passenger side of the car. The easiest way to test without running the motor to temp is with a bi directional scanner that can test run the low speed fan circuit and high speed fan circuit. IF you don't have such a scanner handy, a good independant shop could do this for a nominal fee. I have the alfaobd program and it can do such checks quite nicely.

  Next step should be a cold pressure test of the cooling system, this will show leaks where they may be and possibly "burning off" when the motor is running. Another common failure for coolant loss is from leaking gaskets between the thermostat housing assy and the cylinder head on the 2.4's .

BEFORE throwing parts at the car, get a good inspection done on it for the cooling system so you don't buy and pay labor for unneeded work.

My daughter in laws 2.4 has 125k miles and still no water pump issue. They seem to use a decent pump. The plastic manifold on the side of the engine that does cabin heat is a problem like 5rebel9 is saying. We fixed two leaks on this assembly.

Bottled Water

 

This assembly has the separate thermostat for cabin heat. I bought the whole Gates assembly because the dealer unit was 3 times aftermarket price. Then had a constant drip with the new unit. Ended up moving all new seals to the old factory manifold, no leak afterwards.

 

Just look where the red crusty dried glycol is collecting. Pic is of plastic manifold. Oring on coolant temp sensor is also another leak spot. Might have two problems, fan speed and a coolant leak.
