  • Decent quality, metric threads.
Decent tank. Weld quality is good. The fitting sizes are some wierd metric that will need an o-ring to seal up against. The fitting threads are formed in and the aluminum is thin for them to hold in. I used it as hydraulic reservoir for the power steering on my tractor.

  • Great tank for monitoring coolant or fluid level
Moved the fittings to the right spots for a coolant tank between my broken overflow tank and it works well. Size is small but decent and I just used zip ties to put it where I wanted it. The check side is great for a gauge and it works well. If you need to adjust stuff it has compression fittings you press in to remove the level tube and then you can put the level part on whatever side you want then put the in and out fittings from top to bottom. Mine are set so OEM coolant tank is top line and radiator side is bottom line. I had to mount this between the bumper for my Camaro, but I just fill the tanks, purge the air in my long lines and have a stant radiator cap with the red flip relief valve. There is a science to it so just make sure your fluid out line is on the bottom of the tank. If I had this as a one line out tank it would have the top line vertical above gravity so it does not leak out. ... show more
