Description

Genuine Wynns · Part no. W45690

Wynns CV Cooling System Treatment And Stop Leak W45690 is a 1L bottle from the commercial-vehicle range that stops leaks at the head gasket, water pump gasket and around the cooling system, and keeps protecting against rust and corrosion afterwards. It is formulated not to block radiator channels or temperature sensors.

Good to know

  • Who is the 1L size for? Fleets and owners of lorries and other commercial vehicles; it saves buying several small bottles per vehicle.
  • Can it stay in the system? Yes, it is meant to circulate as a treatment, sealing small leaks as they start and adding corrosion protection.
  • When is a sealer not enough? A leak sealer can only close small leaks; a split hose, a failed water pump or a badly blown head gasket needs the part replacing.

Which one?

For heavy plant where a stronger fibre-based sealer is wanted, K-Seal Heavy Duty (K5516ND) is the other choice. For a car, the 325ml Wynns Cooling System Stop Leak (45644A) is the matching smaller bottle.

Key features

  • 1L treatment and stop leak
  • Stops head gasket and water pump gasket leaks
  • Rust and corrosion protection
  • Won't block radiator channels or sensors
  • Safe for hoses and gaskets
