Stops leaks safely, quickly, and easily. Compatible with all antifreeze and coolants. Safe for all metal, plastic, and rubber cooling system parts. On a card.

Mixture of seven organic ingredients designed to permanently seal holes and cracks in radiators, water jackets, and cylinder heads. Just pour into the radiator while the engine is running, it seeks out holes, and swells shut as soon as it comes in contact with air. Will not re-dissolve, and draining or flushing will not affect the seal. On a card.

Seals even large leaks without interfering with the flow through the radiator and heater core tubes.

Intended for cars with heavier build ups of rust, radiator and heater core deposits.

Circulates through the cooling system., Seals leaks, stops head gasket and combustion chamber seepage, prevents rust and lime from forming. In a plastic bottle.

Stops leaks safely, quickly, and easily. Compatible with all antifreeze and coolants. Safe for all metal, plastic, and rubber cooling system parts.

Easy-to-read dial face. Tests hot or cold. Helps prevents winter freezing and summer overheating.

Proprietary cleaning agents removes rust deposits and oily residue in one easy step, helps Anti-Freeze/Coolant efficiently flow to all parts of the cooling system. In a plastic jug.

Sprayable sealer that forms a rubber barrier to stop leaks. Wicking action seals hard-to-reach leaks without the need for disassembling or removing parts. Designed for low pressure leaks in hoses, oil pans, differentials, transmission pans, fluid reservoirs and plastic, PVC and metal pipes.

Safe and tasteless for fresh water and plumbing systems of boats, RVs, homes, and trailers. Protects from bursting to -50 degrees Fahrenheit. Ethanol Blend. Not recommended in marine engines, marine toilets or as heat transfer fluid. Safe for copper, brass and plastic (except acetate). Use full strength, no mixing required.
