A blown head gasket causes loss of compression, oil contamination and overheating — this genuine OEM replacement seals correctly the first time.

✅ Compatibility

  • FH series (verify your model number before purchasing)
  • FX series
  • FR series
  • FS series

⚠️ Important: Always verify your exact engine model number and serial number before purchasing. Kawasaki engine series share many part numbers but not all parts are interchangeable between variants.

🛠️ Part Details

  • OEM Part Number: 316370-1121B
  • Replaces: Verify with your Kawasaki dealer or engine manual
  • Brand: Kawasaki — Genuine OEM
  • Type: Original Equipment Manufacturer (OEM) replacement

⭐ Key Features

  • OEM-spec multi-layer or composite construction for your engine's compression
  • Precision fire ring bore seals combustion gases at correct pressure
  • Correct thickness maintains OEM compression ratio
  • Oil and coolant passage seals prevent cross-contamination
  • Torque-to-yield design provides uniform clamping across the head

🔧 What Problem This Solves

  • Loss of compression causing hard starting and low power
  • White exhaust smoke from coolant entering the combustion chamber
  • Oil contamination in the coolant or vice versa
  • Overheating from loss of coolant due to external head gasket leak

  • Part Name: Cylinder Head Gasket
  • Material: Multi-layer steel or composite fibre with rubber seals

  • Condition: New — Genuine OEM

🔨 Installation

  • Difficulty: Advanced

Worked when nothing else did, easy, with just a scrubbing pad!
Material Type: Powder Ox, Size: 16 oz
I bought a Catalina 1977 sailboat. The hull (freeboard) was extremely oxidized, dull, and had stains and discoloration from the water running off the deck for years; it was streaked. Everything I tried to clean it did little, until a dockmate told me about this. WOW! It WORKED, and it worked very easily. It reminds me of the old "comet" cleanser, that shakes out of a can -- who knows, maybe its the same thing! A little goes a long way, and with very little elbow grease, I was able to attack the discoloration. Great. I also used it to clean my lifelines, which had discolored quite a bit -- and they now look like new. I LOVE this product, but probably won't buy it again for a few more years -- it lasts that long. Can't recommend it enough!

Poli cleaners.
Material Type: Powder Ox, Size: 16 oz
Our trailer was extremely oxidized. I used the Poli wash and fiberglass cleaner, super easy. It removed the oxidation and made our trailer look new again. Next I will try the Poli sealer.

Works OK.
Material Type: Powder Ox, Size: 16 oz
With a lot of work and diligence (elbow grease), the product works at removing oxidation. I expected it to easily remove the old Poliglow as well. Still lots of work. It will NOT remove the brown water stains from the roof of my molded fiberglass camper. Product is OK, but does not work as easily as advertised.
