Great price for concentrate
About half the price than what you get at the parts store for a 50/50 blend. Make sure to dilute it with distilled water.

BEST 1992-2001 VOLVO Antifreeze on the Market!!
This is the most recommended Antifreeze by Certified Volvo Technicians for the 1992-2001 Model Cars.. This G-O5 surpasses even the Blue Factory Volvo Antifreeze in all the tests. I like the G-05 because in an emergency pinch you can safely mix it with a similar Antifreeze just be sure to flush the system immediately once the issue is fixed, unlike the Blue Factory Volvo which cannot be safely mixed whatsoever.. These Authentic Series of Foreign Volvo have been known to last over 300,000-400,000 miles with proper routine maintenance, they are truly the last series of Authentic Foreign VOLVO's that were built like tanks. Outstanding product, price, value for the money, longevity, and high performance.. Thank you for supporting America and it's Armed Forces!!

It worked
I would give more stars but there was no cost savings. It was just less of a pain than ordering from a box store

Great price on a specialty coolant not available everywhere
It seems silly to buy jugs of coolant online but this coolant is generally not available in stores in my rural town. This is advertised to be equivalent to Ford "Gold" coolant and is recommended for my 2003 6.0 diesel.It works as it should and saves me a drive to the Ford dealer or to a store that stocks this coolant.

The best there is.
A lot of Fords from the late 90s all the way through the 2000s really benefit from running this stuff. I think it's a little better and longer lasting than the Motorcraft version. It does a great job of preventing rust and scale buildup and the boil over protection is really impressive. I've had vehicles with this stuff in their cooling systems that would sit in the driveway for years barely driven, and there was no sign of rust or scale or any other problems.
