Review on 💦 TSI Supercool Radiator Dye, 1 oz - Single Application by Dan Quiceno

My father's car had an oil leak but we couldn't find out where. We replaced the valve cover gasket which reduced the leak, but in doing so we found that the Vtec solenoid valve gasket was old and hardened and needed to be replaced. Now not a drop of oil escapes. The color also shows very well during the day when you are in the shade. Definitely recommended for hard to find oil leaks.
