Sierra Coolant

Liked the product. Is currently the coolant flavor for the time being.

Don't buy

This item says 6 but you get one! The price is way over what it should be for a single gallon. Amazon nor provider have corrected this misleading Qty amount after being told many times it would seem, so people keep getting ripped off.

Good health to your pets

We have lots of dogs and they love the taste of antifreeze, but it will kill them. This eliminates that problem.

Shipped “not new” product that was previously opened.

Ordered two gallons. One of the containers was already opened. See photo provided.I will not use the container that was previously opened! What’s in it? Did someone mix it to a ratio already? How did this get sold?!!!

Quality product, does the job for Marine applications

Shipping on this was an issue. Delays posted twice, vendor didn't confirm shipment for over 8 business days. Great product, not a reliable vendor

Not advertised correctly.

Misadvertised. This item said it came in a "pack of 6". I only received one gallon. The way it was posted, I should have received six gallons. What is going on?
