Avoid Mixing Coolants

03/07/2018

Mixing different types of coolant can have unexpected and undesirable effects which may damage expensive components, so always use the right one for a top up or refill. If you're in any doubt about what's already in the cooling system, drain and refill with fresh coolant that follows the vehicle manufacturer's recommendation.
