- Reconnect all components, refill the cooling system, and check for leaks after starting the engine.
Troubleshooting & FAQ
How do I confirm this gasket fits my exact engine?
This part fits all models in the Yanmar 4LH and 4LHA series. Please cross-reference your engine model with our compatibility table and verify against the OEM part number 119100-12113.
What are the signs of a failing intake manifold gasket?
Common symptoms include visible coolant leaks around the manifold, engine overheating, rough idling, or a loss of engine performance. A diagnostic check can confirm a leak.
Is this gasket reusable?
No. This is a single-use gasket. It is designed to crush and seal once. If the manifold is removed for any reason, the gasket must be replaced.
Do I need to use sealant with this gasket?
This gasket is designed to be installed dry. Applying sealant is generally not recommended unless explicitly specified by your engine's service manual for your specific model.
What is the recommended replacement interval?
Gaskets should be replaced whenever the intake manifold is removed for service or during a major engine overhaul. They do not have a fixed service hour interval but should be inspected for signs of degradation.
