Review on DEEFILL Cooper Washers Coolant DFL 031 by Owen Houser
Underperformed and overpriced coolant
As an automotive enthusiast I was disappointed with this coolant .As my tests showed, it failed to keep my engine running cool during extended track sessions. The packaging and marketing suggested a high-performance product, but it didn't deliver. The only pro is that it did not cause any damage to my engine. However, the price is much too high for a product that doesn`t perform as advertised. Don't waste your money on this one..
- Effective in preventing corrosion and leaks in cooling systems
- Slightly more expensive than other brands in the market
