Quick answer

To replace Redcat part 25036-4, confirm your engine uses a 4-bolt cylinder gasket, then remove the old gasket, clean the surface, and install the new one before reassembling the cylinder head.

Why the 4-bolt distinction matters

The 25036-4 gasket is specifically designed for engines with a 4-bolt cylinder pattern. Using a gasket with the wrong bolt count can cause compression loss or damage. Always match the bolt pattern before ordering.

Step-by-step replacement guide

  1. Confirm your part number: Check the existing gasket or your engine manual for the part number 25036-4. Verify the bolt pattern is 4-bolt. A common mistake is assuming all cylinder gaskets are interchangeable; the bolt count must match.
  2. Gather tools and the new gasket: You will need a wrench set, a clean cloth, and the Redcat 25036-4 gasket. Ensure the engine is cool and the vehicle is stable before starting.
  3. Remove the cylinder head: Loosen and remove the bolts securing the cylinder head. Lift the head carefully to avoid damaging the piston or cylinder walls. Place the old gasket aside for comparison. Note the orientation of the old gasket to ensure the new one is installed the same way.
  4. Clean the mating surfaces: Use a clean cloth to wipe away any old gasket residue, oil, or debris from both the cylinder and the cylinder head. A dirty surface can cause the new gasket to fail prematurely.
  5. Install the new gasket: Place the Redcat 25036-4 gasket onto the cylinder, aligning the 4 bolt holes. Do not use any sealant unless specified by the manufacturer; the gasket is designed to seal dry.
  6. Reassemble and torque: Reattach the cylinder head and hand-tighten the bolts. Then use a torque wrench to tighten them in a crisscross pattern to the manufacturer's specification. Over-tightening can warp the head or crush the gasket. Check for even compression by rotating the engine by hand before starting.
