Genuine Honda Water Outlet Gasket (19352-PNA-000) - K20A & K24A1
A coolant leak from the back of a K-series engine is often this gasket. The water outlet gasket seals the coolant outlet to the cylinder head, and when it hardens and fails over the years, you get a coolant leak that's easy to misread as something bigger, a head gasket, a hose, a housing. This is the genuine Honda replacement, the correct gasket to fix that leak and keep the cooling system sealed.
The Coolant Leak People Misdiagnose
Worth understanding, because a leak here gets blamed on worse things.
The water outlet is where coolant exits the cylinder head, sealed by this gasket. Like any rubber or composite seal, it hardens and shrinks over decades of heat cycling until it stops sealing, and then coolant weeps from the outlet area.
Because the leak is at the back of the engine near the head, people sometimes fear a head gasket, an expensive, involved repair, when the actual cause is this cheap outlet gasket. If you've traced a coolant leak to the water outlet, or you're losing coolant and seeing dampness around that area, this gasket is very likely the fix, at a tiny fraction of what a head gasket job costs.
Replace It Whenever The Outlet Comes Off
Practical rule for this gasket.
Any time you remove the water outlet, chasing this leak, doing a coolant system refresh, replacing the thermostat or outlet housing, or during a rebuild, replace this gasket rather than reusing it. An old gasket that's been compressed and heat-cycled won't re-seal reliably once disturbed, and it's cheap enough that reusing it to save a dollar is a false economy that risks a leak.
It's also worth doing proactively on a higher-mileage engine you're going through, since the original is well past its best and it's a cheap insurance item while you're in the cooling system anyway.
Genuine Honda, Sealed Right
On a coolant gasket, correct material and fit are the whole job.
This is the OEM Honda gasket, made to factory dimensions from material that resists the heat and pressure of the cooling system, so it seals properly and lasts. A cheap aftermarket gasket that's slightly off or made from lesser material can weep again before long, putting you back into the job. At this price, the genuine part is the obvious choice.
It's a direct replacement, so it fits where the original came off with no modification.
