Description
Mannol Radiator Flush 9965 cleans rust, scale, lime deposits, degraded antifreeze residue and other contamination from the radiator, heater matrix, engine waterways and cooling-system pipework. The acid-free formula is compatible with all coolant types and neutral to common cooling-system metals, alloys, plastics and rubber, making it suitable before a routine coolant change or when cleaning a neglected system.
Add the contents of the bottle to the cooling system, set the heater to hot and run the engine at idle until normal operating temperature is reached. Continue circulating the cleaner for 10–30 minutes according to the level of contamination, then drain the old coolant, flush the system with clean water and refill with the correct antifreeze or coolant for the vehicle.

Warranty
Buy with confidence: all new parts sold by Twinwoods 4x4 include at least 12 months manufacturer warranty against defects in materials and workmanship under normal use.
Some products and brands may include a longer warranty period where this is provided by the manufacturer. Where applicable, this will normally be stated on the individual product page or covered by the manufacturer’s own warranty terms.
Warranty cover applies to manufacturing defects. It does not cover misuse, incorrect fitting, competition use unless stated, contamination, modification, damage during installation, normal wear and tear, or failure caused by an unrelated vehicle fault. For certain components, proof of professional fitment may be required.
Warranty claims may require the part to be returned for inspection and/or supplier testing before the claim is accepted. Any advance replacement is discretionary.
Warranty remedies relate to the part itself, meaning repair or replacement, or refund if those are not possible. Warranty does not cover labour, removal or refitting, diagnostics, consumables, travel or other incidental costs.
This warranty is in addition to your legal rights and does not reduce those rights.
