JZ Coolant bypass delete
Made to work in conjunction with a gutted thermostat, or no thermostat, this piece replaces the stock bypass tube found on Toyota 1JZ and 2JZ engines.
When gutting or removing the thermostat, there is no longer a way to close the factory bypass tube and water can freely run back to the water pump without passing through the radiator. By blocking the bypass tube, water is now forced to flow through the radiator.
Available in three sizes fitting the 1/1.5/2JZ engines
