I need to replace the water pump on the 04 Denali. Should I buy the $130 NAPA or the oem water pump kit from the stealer for $300? Any other brands that could trusted?

 

Also need a system flush, I guess that's straight forward.

 

Thanks

Check rockauto.com . They sell AC pumps as well as other brands. They usually have good prices on AC pumps

I don't think I've had an aftermarket pump leak, as long as you get the premium one(like napa's).. most of the premium ones are not reman, and they have a lifetime warranty, where GM's is what, 90 days?

I put over 200,000 miles on my 99 6.0L before I changed the waterpump out of fear of it failing on the road in the desert. I got 200,000 miles out of a factory pump...I put a factory pump back on, NAPA lifetime warranty not withstanding. I think I paid well under $200 from a mailorder house like GMPartsDirect.com. Your experience may suggest a different path.

I agree I would go with a factory pump again, but I would def stay away from the stealership. I have ordered a few oem chevy parts from www.gmpartsclub.com and find they better prices than the stealership. gm partsdirect also has decent prices but I have found their customer service to be poor.

Should not matter. Just make sure you use the best gaskets (ie fel-pro). If you don't you're gonna be doing the job again real soon.

Use OEM gaskets.

That's fine but, the Fel-Pro will work just as good or better.

I bought a new NAPA water pump today, it's a Gates for $123. Every easy process to change pumps. I was surprised how easy it was to complete the job.

 

The only thing that makes a little worried is the pump I took off had the exact gaskets as the new ones I put on. It makes me wonder if the previous owner had replaced the pump prior. They were the metal with orange O rings. The pumps had different markings, the one I took off had a lot of numbers and the gates looked more blanked.

 

Thanks for all the advice

The gaskets may have been the only thing changed. There have been problems with them.

my autozone lifetime pump came with the metal gaskets with orange rubber/silicone inserts.. My original pump has the same gaskets, no big deal.. those pumps are the easiest waterpump you'll change on a truck.. huge pump though...

It should go without saying that all the hoses should be changed at the same time as the pump. But, I'll say it anyway. That heater hose with the Y is a pricey SOB.

The metal with the O-rings is just what you wanted. The paper one will not work very long.

      Transmission Temperature Hitting 220s

      By Grumpy Bear · Posted

      After I wrote that reply I went for a ride. 85 F out. So trans started at 85 F and it shifted the same as it did an hour latter at 168 F. I've never actually recorded the to cold to shift point but it is under 32 F before they start hanging on to a lower gear or leaving the converter unlocked. Both intended to heat fluid.    Yes, brake or bake. Absolutely.      Your welcome. True research ended decades ago. Field trials are still in play.    There is a thing called oxidation onset temperature. This is the heat related oxidation not the O2 exposure kind. For mineral oil that starts at 140 F. So what happens after 140 F? Each 20 F cuts fluid life in half! Does using a Full Synthetic improve that? Yes! By how much? Depends on the base oil type and a few other factors. But enough to notice. Some esters are even higher. There are even synergies between types the will raise it higher than any one component is alone.    Then there is "Hindered" oils. Antioxidant additives. Hindered Polyol Esters can sit at 500 F for years in a turbine.   When a blender brags his oil will 'take 500 F" in service he doesn't specify for how long. Water will dance on a 500 F hot plate for several seconds. @newdude put up a chart showing the relationship between fluid temperature and it's life in an automatic transmission. Here's a version of that chart for Group III based oils. These temperatures are those in the pan as observed as 'normal'. that is you drive as you do for as long as you do under what load you ask of it and whatever that temperature is this graph applies to. Flash temperatures of a few minutes isn't what his means.    Note that fluids held at a constant 240 F have a service life of only 20K miles. 220 F explains the factory exchange limit, eh? My equipment I keep under 180 F and I'm good if the cooler will hold it as low as 140 F. But that's me.

      Actual Full Screen CarPlay on Refreshed Silverado/Sierras.

      Im in the same boat. Carlink adapter comes tomorrow and dev account is in process. Would you he able to send the new instructions my way also? Question, do you have to change code and republish app everytime developer updates? Thanks for your assistance, truly the only thing i cant stand about my truck is the carplay limitation

      Weight limit in bed

      By rav3 · Posted

      And Google AI says......... Yes, your truck can technically handle it, but you will be right at or near its maximum limit. A 2016 Chevrolet Silverado 1500 High Country with a 6.5-foot bed has a maximum payload capacity of approximately 1,770 pounds.Weight RealitiesLoad weight: Half a cord of dry hardwood weighs roughly 1,100 to 1,500 pounds depending on the wood type (like oak or hickory).Payload limit: Payload includes the weight of the wood, you, any passengers, and a full tank of gas.The math: If you weigh 200 pounds and have a full tank of gas, a 1,500-pound load of wood puts you right at that 1,770-pound ceiling.Safety TipsCheck the yellow and white sticker on your driver-side door jamb for your truck's exact payload number, as high-end luxury trims with extra features have slightly lower capacities than basic trucks.Expect the rear end to sag noticeably.Drive carefully, avoid sudden turns or stops, and keep speeds low if you have to travel a distance.
