Just got my hands on this Zerex DEX-COOL coolant case and wanted to share my thoughts after using it in my 2018 GMC Terrain.

First off - the price point is fantastic for a quality product like this. I've been using Valvoline products for years and they've never let me down.

The coolant itself seems to be working perfectly so far. No leaks, no overheating issues, just smooth engine performance. Fingers crossed it lasts the full 5 years/150k miles as promised!

Important note: ALWAYS check your owner's manual before choosing any coolant. Not all vehicles take the same type.

Now for the not-so-great part... My shipment arrived with only 5 bottles instead of 6, and the packaging was completely crushed. One bottle had leaked about half its contents during transit. Major bummer!

Despite the shipping issues, I'd still recommend this product based on its performance. Just maybe order from a different seller or ask for extra packaging protection.
