OET Green Concentrate Antifreeze/Coolant for North American Vehicles, 1 Gal.

No issues, it's concentrated so make sure you dilute it.Works absolutely fine for me, no issues.It's coolant. It's bright green. It's liquid. Don't know what else to say!Van was overheating when low on coolant. Added this coolant, van doesn't overheat anymore.

This seems as good as any I've bought so far. I'm no car expert but it seems to be working great.

Sure works lol. Nothing fancy but worked fine for my jeep.

Quality product

This type of coolant only has a rated useful life of two years in use, but with my older vehicles I'm more comfortable using the old school stuff instead of some of the newer formulations. I wouldn't use this on almost any vehicle made in the most recent two decades though, so be sure this is what you need before ordering it.I'm also no fan of "universal" coolants because there are so many potential material incompatibilities.Also note that this type of old formula coolant can often be bought locally and save you some buckaroos, so don't make any assumptions about that.

This is Green Antifreeze, most of the vehicles myself and family own use this stuff. Sometimes it's needed, such as during a refill after flushing out the old stuff, or adding more fresh stuff to replace some lost during something such as replacing a thermostat, heater-core, etc.Peak antifreeze, I don't buy it too often, though I have bought the 50/50 mix in the past, when I was in an emergency situation. Peak is fine, but many stores around here don't bother stocking the concentrate, only the 50/50 mix. Due to that, I normally go to the car dealership and buy their house-brand coolant concentrate. I can always get a gallon of distilled water, and create 2 gallons of 50/50 from 1 gallon of concentrate.At first, the bottle and contents of this Peak Brand Green Coolant concentrate looked good, I can't find it too easily in the stores, so it's interesting to have it around. Examining this bottle, it quickly became obvious to me that something is missing, a thin, opaque, "window-strip" on the edge of the bottle to let me know how much of the bottle's contents are still in there. Most of the time, I get my coolant concentrate from the dealership, and their bottle of Green antifreeze concentrate have a little window-strip on the side of the bottle, showing me the contents of the container, which makes it easier to mix with distilled water. I find it odd, a big brand like Peak doesn't include that on this jug of coolant concentrate.This bottle of Peak brand, green coolant concentrate, I am rather surprised it lacks anything on the side of bottle to show me where the contents of the jug are at. I have a number of antifreeze jugs around here that have that transparent strip on them, so I'm alright, but it still surprised me that Peak decided not to include that on this bottle of concentrate. It appears to be decent antifreeze, Peak is well-known, but the bottle it is packed in is inferior to the simple Red plastic jug of Green coolant I can get at the dealership that includes a fluid level window strip that allows me to see how much of the coolant is left in the jug. C'mon, Peak!
