    Bottom Line
    Yes, I would recommend this to a friend.

    Great stufff helps engine heat up faster in the cold.
    By  MATTHEW,  a  Verified Buyer  from  Brantford Ontario Canada  on  February 05, 2025
    Great stuff helps the engine build heat faster in the cold especially here in Ontario. My 07 6.0L Heats up a lot faster now and the coolant temp stays cooler when pulling heavy loads and at the same time helps the engine maintain its own heat even when idling in -20 degree Celsius. Great stuff recommend it for sure. I put this in my Transit and this has helped that van out lots also.
    Bottom Line
    Yes, I would recommend this to a friend.

    Greatly Accelerates Warm up
    By  WILLIAM,  a  Verified Buyer  from  Bremerton, WA  on  January 20, 2024
    For new four cylinder engines in cold especially this is a welcome addition, heat coming on quickly and modestly improving the system's overall performance. Notably impressed with how it has impacted the system health as well!
