TOYOTA 90430-27005 Water Hole Plug Gasket

The genuine Toyota part number 90430-27005 is a precision-engineered gasket (Gasket for Water Hole) specifically designed for engine block and cylinder head coolant passages, as well as associated drain and sealing plugs. Its primary function is to maintain a leak-free seal for the coolant under high operating pressure and across a wide temperature range. Reliable sealing prevents coolant loss, protecting against engine overheating, component corrosion, and potential compromise of the lubrication system.

Technical Specifications and Part Numbers

• Manufacturer: TOYOTA (Genuine OEM part)
• Part Number (SKU): 90430-27005
• Replacement / Alternative Reference Numbers: 90430C0009, 9043027004

Symptoms of Wear and Failure

Cooling system gaskets degrade over time due to continuous thermal cycling and the chemical effects of coolant. Typical symptoms of an aged or improperly reinstalled gasket include:

• Coolant leaks around engine block or cylinder head sealing plugs
• Gradual drop in coolant level within the expansion tank
• Formation of white or bluish crusty antifreeze deposits around sealing surfaces
• Engine overheating resulting from loss of system pressure and fluid deficiency
