Question Re-use factory metal gaskets on new water pump?

Water pump crapped out. Replacement is going on. Have the old one off and the factory metal gaskets still look in very good shape. Shiny, no corrosion and the orange rubber material has no cracks and still seems pliable. So my question is should I re-use these on the new pump or should I go with the paper gaskets included with the pump itself. 75K miles on the old pump, NO leaks from the old gaskets. What do you think, re-use or go with the replacement paper gaskets and sealant? Thanks in advance.

I would reuse the stock ones if they look good.

They do look good, almost new. I would think the quality of a metal/rubber gasket would be superior over the flimsy paper one included with the new pump. Thanks for the reply.

Anyone else want to second my decision or have a reason to use the new paper one instead? Again thanks.

Yea I've reused mine probably 4/5 times before I replaced them. Never did have an issue, last time out I replaced all the oem gaskets with new oem stuff because I thought it was a good idea.

I wouldn't use either of your mentioned ideas, best case is the originals are going on 9 years old and the paper ones will work but are lacking in quality which may give you a hint as to the quality of the Chinese water pump you probably ended up buying.
Go down to your GM dealer and buy new OEM ones. It is not a very hard job to do but it is worth doing it right the first time, and you won't have to do the job twice and have to buy antifreeze again.

Have you even seen the stock gaskets before. That's an idiotic statement with some of today's technologies.

You want to talk idiotic, why would you reuse a 9 year old rubber impregnated gasket that has gone through hundreds of cold-heat cycles. Make that probably thousands of cold-heat cycles.
Exactly which other gaskets that are 9 years old would you recommend using then?

Ones like ours that our designed to be reused, and have been inspected by the OP and based on his description, probably are still OK. Gasket technology has increased drastically over the past 20 years.

Interesting debate so far. I see the merits of both sides. I appreciate the input so far even though its gotten a little heated. I'm leaning re-using as by their condition they look in very good shape still. I doubt my local Chevy dealer carries these for a GTO (unless they are standard for LS block water pumps I suppose) and I've got to get it back on the road by Monday. Again thanks all for the input.

Is it just me, or did I have rubber O-rings on my water pump?

Just don't get angry if you re-use the old ones and they leak.

Just curious, where did you get this new waterpump? Is it actually new? What brand? I got one about 2 months ago from Advance that came with new metal gaskets.

Technology yes! But use common sense! Ok you say they are designed to be reused? After 9 years of use and thousands of cold-heat cycles? If you can point me to one dealer or reputable shop that says it is a good idea to reuse them being 9 years old and the fact that they are about $6.00 a pair from the dealer, I will buy you lunch! Why in the hell would you not spend $6.00 to do it right?

Shit what about the antifreeze that you will have to buy again when the old ones leak? Now we can have the fools that will chime in and say " I reused mine and I didn't have problems" but the other dumb asses that reused their old ones and watched them leak and had to redo the job again surely won't admit to it.

Count me as one of the "dumb asses," then. Antifreeze is cheap, too.

Well then you are a lucky dumbass, in Texas antifreeze = $13.00, water pump gaskets $6.00 a pair from the dealer.

Also if you have owned your car since new then you know the history, and if you bought it used then the water pump may have already been changed and the water pump gaskets may have already been re-used already. For $6.00 it is cheap insurance to buy new ones, or if you didn't buy a Chinese water pump and instead bought a quality water pump it would have already come with the oem style gaskets

Put me in the lucky dumbass list as well. On my car I reused the stock water pump gaskets at least 5 times. No leaks no issues who'd have thought.

I generally prefer new gaskets, but the second time I had my water pump off, I reused the old ones. The world did not end and the pump did not leak. I also reused the exhaust manifold gaskets when I put headers on. Why get fighting mad and start name calling when people disagree?

Upon further inspection one of the gaskets the rubber has separated from the metal. SO............ My local GM dealer parts department is closed today. Another 20 miles away closed at noon and set aside 2 gaskets for me with DIFFERENT PART NUMBERS in their rental department. They are the same gasket as far as I can tell. I'm not driving over 40 miles round trip on this part department employees "hunch". SO............ Autozone in town has 2 metal with impreg. rubber gaskets that I'm off to see if they will do the trick. And yes this is a new (not rebuilt)Duralast pump from Autozone as I don't have the $$$ for a higher $$$ replacement with Christmas coming up, times aren't like they used to be. I'll keep you all informed and I am grateful for all the input. Thank you for the information all.

Im surprised the autozone water pump didnt come with better gaskets to begin with. Autozone carries the Fel-Pro factory oem style as well, you will be fine with Fel-Pro their quality on gaskets is as good as oem.

Got the higher quality metal w/rubber gaskets at Autozone Duralast by FelPro. Last 2 they had, I'm in luck. $10 bucks each, pricier than OEM but they look every bit as quality as the original.

As for the rubber O-ring that came with the cheap paper gaskets with the pump I assume it is meant for the thermostat housing but mine does not have one and I've had it off twice swapping t-stats in the past and have owned since new. Maybe this is for the older t-stat housing possibly.

Now that I think about it. I did replace my water pump gaskets. The only ones I re-used were the valve cover gaskets.

Everything is done and seemingly leak free. (Knock on wood)

I appreciate all the input. Hope no one has any hard feelings after the "debate". But you all helped out a fellow GTO owner.
