Loctite SI5926 is a blue multipurpose silicone instant gasket in a 40ml tube on a blister card, rated -54° to 150°C. It replaces cut gaskets on rocker and timing covers, differential covers, sumps, gearbox pans, water pumps and thermostat housings, on metal or plastic, machined or cast, and stays flexible through heat cycles.

Good to know

• Which jobs is it made for? The usual DIY gasket jobs: rocker covers, timing covers, diff covers, sumps, transmission pans, water pumps and thermostat housings, within its -54° to 150°C range.
• Is 40ml enough for a sump? For one or two covers, usually yes, if you lay a thin bead; for several jobs, a bigger tube makes more sense.
• How do I stop silicone ending up in the engine? Use a thin bead, run it inside the bolt holes, and let it skin slightly before fitting so less squeezes inwards.
• Does it suit exhaust joints? No; 150°C is fine for covers and coolant parts, but exhaust joints run far hotter and need a proper gasket or exhaust paste.

Which one?

For gearbox and cast housings, Loctite SI5660 Silicone Sealant – Grey (2064521) is 100ml and coolant resistant; for higher heat peaks, Granville High Temperature Instant Gasket – Black (0458A) is rated intermittent to 300 Deg C.
