Reusing a Gasket
- If the gasket hasn’t seen heat exposure yet of an operating unit, it might be ok to reuse.
- If the gasket hasn’t seen fluid exposure and swelling of an operating unit, it might be ok to reuse.
Should I replace the gasket on my water pump?
If the water pump is in a bad spot and hard to get to, you may not want to chance it. If it's rather easy to get to, I wouldn't worry about it and reuse the gasket. EDIT (WRT your edit): You may have wet bolt holes, meaning there is coolant behind the bolt. If so, you may want to put some Permatex on each bolt so it will seal as you insert them.
Is it okay to use RTV on water pump gaskets?
It’s okay to use RTV on water pump gaskets. But it would be best if you used it when necessary and in the appropriate manner. Below is a guide that will give you insight on how and when you should use RTV in repairing water pump gaskets. What is RTV? RTV is a popular term, but very few people know what it is and what it does.
Can I reuse a gasket?
A gasket should be assembled, then exposed to heat and fluid. A used gasket already having swelling due to the fluids should not be reused. The third reason not to reuse a gasket is related to the first two. Once a gasket has taken a set (due to temperature and fluids), it should not be disturbed or reused.
What is a water pump gasket made of?
This is a small sheet found on your engine made up of gasket paper, metal, silicone, and plastic polymer. The water pump gasket fills the gap between the water pump and the engine. The water pump is vital because the water flowing from the engine block to the water pump would leak without it.

Can I reuse metal gasket on water pump?
Once a gasket has taken a set (due to temperature and fluids), it should not be disturbed or reused. It would not have the same properties available to go through the initial compression provided by the joint and achieve the initial seal.
Should I replace water pump gasket?
When changing a water pump, replace all old gaskets and seals with new ones. If your new pump comes with a seal, make sure it's in impeccable condition before installing it. (Some seals are so thin you could easily damage them when you rip off the packaging.)
Can you reuse old gaskets?
Gasket reuse after maintenance inspections is not recommended for the following reasons: Most gaskets are cut from sheets containing rubber, binders, and other materials. Over time, as a gasket is in use, these constituent materials in a gasket harden with the passage of time and exposure to operating conditions.
Do you use sealant on water pump gasket?
You don't need sealer on the pump gasket if you already put the sealer onto the pump. The gasket is good enough on the engine, you don't need to put sealer on that. It's a good idea to put it on the pump. Then it stays in place and doesn't move.
How do I know if my water pump gasket is bad?
Overheating: This is by far the most dangerous symptom of a bad water pump gasket....If you see any of these signs and catch them quickly, you may be spared any lasting damage:Your temperature gauge is running higher than normal.Your coolant temperature warning light comes on.You see steam coming out from under your hood.

Are gaskets single use?
Ideally, spiral wound gaskets should be treated as single-use gaskets and replaced once wear and tear or leaks start to occur. It is not advised to reuse spiral wound gaskets. If, however, you opt for solid metal gaskets, for all these are slightly more expensive, you can reuse them.
How do you soften old gasket?
To properly remove stuck gaskets, try soaking them in WD-40 or using a chemical gasket remover to soften or loosen the gasket material. Chemical gasket removers may have features like low-VOC, or may be formulated to work better on a particular gasket material.

Replacing water pump. Do I need to apply RTV sealant to...
You can use the engine silicone sealant on both sides of the gasket. You don't have to goop it on, use it like a glue to keep it in place. Best thing to do is use it to attach it to the pump first, and then make the same small bead on the other side of the gasket but let it sit for about 10-15 minutes before you put it on.
Q: Replacing the water pump using and using a gasket sealer - YourMechanic
What you want to do is get a good sealer (silicon or any other type) and put it on a gasket on the inside. Then you put the gasket on a pump. Then let it sit for a half an hour or 40 minutes and when it is sort of dry, then you can bolt it onto the vehicle.
Water Pump Paper Gasket With RTV? Longevity? | Bob Is The Oil Guy
Most water pump gaskets seem to be made of paper, only in some rare applications do I notice that they use a metal gasket with rubber O-ring of which I would assume seals better than paper. I noticed the official manufacturer recommendation (eg. from Fel Pro) is to install the paper water pump...

Why should gaskets not be reused?
A gasket should be assembled, then exposed to heat and fluid. A used gasket already having swelling due to the fluids should not be reused. The third reason not to reuse a gasket is related to the first two. Once a gasket has taken a set (due to temperature and fluids), it should not be disturbed or reused.
Why do you need a new gasket?
A new gasket is required to go through the initial seating phase and achieve a proper seal. Exposure to fluids sometimes causes materials to swell, impregnate, or saturate. In a seal situation, this often helps to create the seal. Reusing a gasket is not advised as the saturation and absorbancy condition can vary.
Why do gaskets deteriorate?
Exposure to elevated temperatures causes materials to deteriorate. Sometimes this means: dry out, stiffen up, saturate, get brittle, take a set, etc. Once this seal has “seated” in the application, it should not be disturbed. A new gasket is required to go through the initial seating phase and achieve a proper seal.
Can a gasket be disturbed?

Exposure to fluids sometimes causes materials to swell, impregnate, or saturate. In a seal situation, this often helps to create the seal.
Can you compress a gasket?
If you’ve never given much thought to gasket compression (gasket what?), you likely have the mindset of “clamp ‘er in there the best you can”. While this mantra may work for you in certain scenarios, it is definitely not ideal. Achieving the proper gasket compression via the torque placed on the bolts is actually a well-engineered, tested and verified process done with a specific type of gasket material.
Can a head gasket fail?
Sometimes bad things can happen to good engines. This can be the case with a head gasket failure. Depending on the design requirements and the suitability of your gasket material for the application, the useful service life will vary. However, any application that is in use long enough may require a replacement of the head gasket...

Can you reuse head gaskets?
Even some MLS (multi-layered steel) head gaskets can be reused under the same conditions. That said, it's always a crap shoot reusing gaskets. In the case of metal or malleable, you're in good shape most of the time. Once in a while, the gasket, even while looking completely good, will still leak.
Can you use Permatex on metal gaskets?
PS: I would not use any Permatex on the metal gasket. They really aren't designed to have sealant applied to them.
Can GM intake gaskets be reused?
Metal and malleable material gaskets (like are found in GM intake gaskets), can be reused if there isn't any apparent damage to them. Even some MLS (multi-layered steel) head gaskets can be reused under the same conditions.
Can you use an old gasket on both sides?
Paulster is right but if you are going to use the old gasket I suggest putting some RTV on both sides to make sure it seals. But if your going to buy RTV you mind as well get the gasket since it can't cost much more than RTV. Unless you need to drive it tomorrow and can't wait for the new gasket.
