I had to replace my coolant resevoir cause a buddy of mine broke the top hose inlet off into the hose. Last summer I bought a OEM replacement but that one leaks too. So, instead of looking for a used one again, I bought a Canton. As far as I know, they are the only ones that make an aftermarket coolant tank.
