- Open cap of cooling system slowly; turn a conventional coolant cap as far as the first detent and turn a screwed coolant cap approx. 1/2 turn and release the pressure.

Wear protective gloves, protective clothing and eye protection. Do not pour coolant into beverage bottles.

First aid measures

^ Rinse affected skin with large quantities of cold water and cover with sterile bandages.
^ Allow the person affected to drink plenty of water with the addition of medicinal charcoal.
