591‑7736 GASKET is a 1.98 mm thick cylinder head gasket designed for CAT 3512, 3516 and 3516C heavy‑duty diesel engines. Installed between cylinder head and engine block, this multi‑layer metal‑fiber composite gasket seals combustion chambers, oil galleries and coolant passages. It withstands high combustion pressure, fluctuating temperature and engine vibration, preventing coolant leakage, oil seepage and gas blow‑by to keep the engine working stably in generator set, mining and industrial power applications.

Installation Guide
Completely shut down the engine, allow full cooling before disassembly to avoid scald risk.
Thoroughly clean cylinder head and block mating surfaces, remove old gasket residues, carbon deposits and burrs.
Inspect new 591‑7736 gasket for cracks, creases or transport damage before mounting. Do not reuse old gasket.
Place gasket in correct orientation, install cylinder head and tighten bolts step‑by‑step strictly according to OEM torque sequence and torque values.
Complete assembly, refill coolant and engine oil, perform idle trial run, monitor engine temperature and check for leakage.
Maintenance Tips
Keep cooling system well maintained; avoid sustained engine overheating which is the main cause of head gasket failure.
Follow OEM torque procedure during installation; uneven torque will lead to incomplete sealing and premature gasket damage.
Inspect coolant and oil condition regularly for signs of cross‑contamination.
When replacing cylinder head gasket, inspect cylinder head flatness; resurface or replace warped cylinder head if necessary.
