When to replace waterpump?

Last week I was at 315k miles now I am at 320k. Looks like I am having some cooling issues. I plan on doing a leak test tomorrow. Should I just replace water pump now? Is there anything else related I should replace due to high miles?

 

Regular coolant changes, if so what intervals? When was the thermostat replaced?

Couple options that could lead to rising temps. Unless you are doing a cooling overhaul.

 

Still have the original radiator?

 

I just did a flush, thermostat, and radiator cap. I am losing about half a gallon of fluid every 200 miles.

 

dang!!! And you aren’t seeing it coming out of the weep hole? Have you taken a look at your oil?

 

Yes still same radiator.

 

No just got back from Utah. What is a weep hole/

 

Fan clutch is a good one to replace with water pump. I’d find the source of the leak first tho. Before throwing parts at the problem. That’s what going to the speakership is for lol

 

small hole in the front of the water pump. It will often drip fluid if the water pump goes.

check your oil. If it looks milky, that would narrow things down.

 

Ok. I will do it now

 

Looks like the oil is good. Fluid is coming out weep hole.

 

yup its time for a new water pump.

 

there you go!

 

Are you the original owner? 320 is an impressive run on the original water pump.

 

Losing half a gallon of coolant every 200 miles should have created a puddle under the truck. I don't mean to alarm you but I'd be concerned of having a blown head gasket. Hopefully, you simply didn't notice the puddles for whatever reason.

I am about to do a lot of coolant component replacing as preventive maintenance for truck's 200K mile anniversary - radiator, fan clutch, fan, thermostat, radiator cap, and various small hoses (five of them, not counting the two radiator hoses).

 

Yes, one owner truck.

 

Damn impressive.

 

I am just going to do the fan clutch and water pump. Yes, I have my concerns, but water pumps are not pricey and will need to be done sooner or later. I have an Aisin kit coming tomorrow and will do the install with a buddy.

 

320……..WHOOT!

 

I have to thank some of the peeps on TW.
