Holts HREP0062A Wondarweld 250ml - Professional Cooling Syst

Holts Wondarweld Cooling System Leak Repair (250ml)

Holts Wondarweld is a heavy-duty professional repair liquid designed to solve catastrophic internal cooling system failures, including cracked engine blocks, blown head gaskets, and leaking cylinder liners. Unlike standard sealants, Wondarweld is a "heavy-duty" solution that does not clog the system; it circulates through the coolant until it reaches the point of the leak, where it hardens upon contact with the air or high-temperature combustion gases. It provides a permanent, high-strength metallic seal capable of withstanding the intense pressures of a running engine. This product is a proven, cost-effective alternative to major engine teardowns or engine replacements.

Automotive Industry Suggested Uses:

• Major Internal Leakage: Repairing cracked heads and blocks where coolant is escaping into the combustion chamber (white smoke from exhaust).
• Engine Salvage: Restoring the integrity of a cooling system on high-mileage or classic vehicles where mechanical disassembly is not economically viable.
