Useless product

Verified Purchaser

Poured the whole container into reservoir and added antifreeze as needed. Drove the vehicle for 30 minutes and had to add more antifreeze as this product did not stop the leak.

Q: how do I use it for an Audi 2012

2 years ago

2 Answers

A: Simply shake well and put it in the pressurised overflow ysnk, after ensuring the engine is cold and enough room in the over flow. Idle the engine to operating temperature, than re check the coolant level. If it requires more to bring to the full mark, let engine cool and add the necessary approved coolant.
