Thanks! But I looked it in the book at Walmart at the time, and it said my spark plugs were Bosch. Hmmmm...

Yep! I will have them do so. The service writer said the mechanic will inspect the hoses, and they can tell by that when the hoses will go.

I wonder if I should also replace the two heater hoses and the thermostat bypass hose and the overflow tank hoses??

Thanks to the SportyandMisty, trlhiker, southernnaturelover, and Unit731. I tried to multiquote you. Hope it works.

My coolant overflow tank has always lost coolant from day one, so I have them add some coolant at each LOF. The radiator itself does not appear to leak since the fluid is always within an inch or two of the neck. I might check the pump myself or have them do it. It's a complex job since there is a side cover covering the serpentine belt, and I am not sure how easy that will come off or if you need ramps or jack stands.

The last time I changed a water pump it was a 1964 Buick. They just don't go out like the used to. As for the serpentine belt, I last changed one on a 2002 Jeep Liberty at 95,000 miles when it started to show cracks. Before that, a 1997 Escort with 155,000 miles. All of my other cars have never needed one while I had it, but I rarely keep them more than 140-150k miles.

That's because Walmart doesn't carry premium plugs from NGK or Denso. Sure, their book 'recommends' Bosch plugs but your owner's manual will tell a different story.

Is this the 3.5L Toyota corporate V6? It's a good engine, but the water pump is a known weak-point. Mine failed at just before 100K miles. And because so many widgets need to be removed to access the water pump, the shop manual considers this to be a 4-hour job. If the dealer will only add $100 for parts, to do the water pump, then I wholeheartedly recommend getting it replaced as a preventative measure.

Default Water pump / serpentine belt

Hey Bro, I wait until my pump goes out. Some pumps are very expensive and a ***** to get to. If you know for sure it's going out, absolutely change it A.S.A.P. Otherwise, you're going to begin to know it's going out cause you'll begin to overheat. It could be your thermostat, which is a lot cheaper. If you're overheating, use a rag and squeeze the top radiater hose. If you can't squeeze it, it's your thermostat.
Your belt is expensive too, but not hard to change. I check it all the time for cracks and tension.
Happy driving

Ha, well I guess I wasted my money by buying those cheap Bosch spark plugs then. Lesson learned!

I might very well do that then. Yep, it's a 3.5 L V-6! I agree...great engine.

Thanks Money Suckered. I agree...the water pump is a pain to change out. I never knew about squeezing the top hose trick. I hope I remember it if I ever start to overheat!
