I had over heating problems. Went looking for a new coolant to help solve my problems, found Penrite Green long life coolant and have not looked back. Diesel Hilux is running great. Even staying cool of 40 degree days and loaded up in weight. Great buy.

The product is good, but the packaging is useless - lid doesn’t fit properly so it spills out everywhere if it falls over - I now have glycol in my boot which is oily and hard to get rid of.

What could be easier? Grab the coolant, chuck it in the overflow bottle and bob's ya mothers sister.
Pre-mixed coolant is great. No calculations no messing about just straight in and it works. These collants are also compatible with others making them a safe choice unlike others. Overall it's a great value and safe choice to use under the penright brand name.
Great product have used it in all my motorcycles and xr6turbo. Great product. Main reason for buying the product is it is Australian made and is very easy to use no stuffin around.
Have used this product for many years. Great quality for a fair price. Happy to recommend this product.
I ordered click and collect and was ready super fast. Got the premix as I just serviced my car and wanted a easy to use premixed coolant for the falcon. Great viscosity and ready for use. Drove round for two days now and everything going well. Will buy more for the next time I need to add in or flush out my radiator in the future.
Great recommend! Managed to purchase on sale too! I googled what would be best for my mazda 3 & this popped up
speaks for itself doesnt it. dont use water if i can avoid it, some people would argue that it causes rust throughout, coolant is for the radiator, not water.
