[A necessary evil?]

One of the problems is that the bushing in the water pump wears in for a certain eccentricity. When you remove and replace the fan clutch or even fan blades (like when you replace the timing belt) and remount them, the ballance will be different (most likely). This causes new, different wear on the WP bushing, often enough to cause it to fail...

This makes sense. I read on a BMW site that they recomend replacing the water pump at every other timing belt replacement. And their timing belt replacement schedule is the same as the 92 Pathfinder....every 60k.

 

Also, I don't think the water pump is driven by the timing belt. Isn't it on one of the other belts?

 

Thanks everyone for all the info.

[What is this?]

will let you start the truck without depressing the clutch for sticky situations.

just press it and once and start the truck. not in gear though!

 

 

The manual gives steps to using it.

 

1 set parking brake

2 depress brake

3 put in first gear or R to move backward

4 put left foot on brake and release parking brake

5 turn ignition switch to "on"

6 press and release the interlock

7 turn ignition to start while at the same time depress accelerator. As the truck moves take left foot off of the brake.

 

Hope this helps

I dont think the water pump would "cause" timing belt failure. But waterpump failure would cause massive loss of coolant and overheating.

 

I replaced my timing belt a little while ago. Decided not to replace the waterpump at that time. A week later the water pump went out.

I then had to do more or less the same amount of work to get to the busted waterpump, clean it all up, and install a new one.

 

The reason people do them at the same time is that to get to the waterpump you have to take all the timing stuff off. The pump itself is only about 50 bucks, its the labor cost of scraping the old gasket off the block that causes the price to jump that much. Ask them how much a waterpump would be seperate from the timing belt? I bet it comes to more if they do them separately.

 

Better in the long run to do both at the same time.

 

 

Thanks for the response. Your water pump went out a week later? What a coincidence. I just wonder why in the manual they have no replacement intervals for something so crucial as a water pump....... Makes you think the pump is designed to last.

I'm about to have my timing belt replaced and after looking at the configuration and location of the water pump, I just don't see where or how it would cause the timing belt to slip unless it (the water pump) was just plastered. And if it was leaking that bad, wouldn't I know it before it was so bad that it caused slipping of the timing belt.

 

Seems like an un necessary expense if my water pump is perfectly fine. I can get the timing belt replaced parts and labor for around 220....but add the water pump and it jumps up to almost 400 dollars. Seems like a rip off .

 

So, how many of you guys have actually had experience with the water pump causing the timing belt to go out? Thanks in advance.

[Colorado]

Aurora/Denver here, where are all the Rocky Mountain Runner's at?

 

 

One here, just moved here (Denver) and bought a Pathy. Love it and as soon as I get some maintainance stuff done (timing belt, starter, alighnment)....I'm gonna take her out to see what I'm workin with.
