Review on 🆒 Dorman 603-001 Coolant Reservoir Bottle in White: Reliable and Efficient Cooling Solution by James Khalifa

As a result, you get what you pay for. I used these tanks as an oil reservoir for a 2-stroke engine. The tank was mounted on a rubber-based frame away from engine vibration. I bought three new tanks a few months apart and all three are leaking at the seams on the bottom (near the nipple). Unfortunately, every tank leaked worse and worse. The third tank was assembled the same way and as soon as I poured oil into it, it started to flow immediately. I spoke to a Dorman technical representative to discuss my concerns and he informed me that their tanks are made of high density polyethylene (HDPE) and HDPE is not rated for petroleum products. I then informed the technical representative that the advertisement for this tank contained anti-freeze and anti-freeze IS a petroleum product. I also informed him that almost ALL of the various engine/transmission oil containers and fuel cans (petrol and diesel) were made from HDPE. Then he told me that their products were not designed for petroleum products. SMH Save yourself time and hassle and order a quality container from US Plastics.
