Rite-Blend™ Leak Detection Dye

For Extended Life Coolants

For best inspection results, use a high-intensity Tracerline® UV or UV/blue light lamp.
Wear protective glasses supplied with the inspection lamp. The dye will show best under
low light conditions.

Adding Dye and Inspecting for Leaks

• Turn OFF the engine. Make sure the engine is cold before removing the radiator cap to add dye.

Use 1 ounce (30 ml) of dye for every 6 gallons (23 liters) of coolant.

• Run the engine and vehicle heater until they reach full operating temperatures so the dye circulates.
Smaller leaks may require longer run times.

• Turn OFF the engine. Scan the system with a Tracerline
reach areas, use a mirror to reflect the light. As an alternative, wipe suspected areas with a clean
cloth and check the cloth with the lamp for traces of the fluorescent dye. All leaks will show with a
bright fluorescent glow. A small amount of dye may be added to increase the glow. Additional dye
will not harm the system.

• After the leaks are repaired, clean the dye residue from the leak sites with Tracer Products’
GLO-AWAY™ dye cleaner/remover or a general-purpose shop cleaner. Reinspect with the lamp to be
sure that no dye remains. Run the engine for another 5 to 10 minutes and reinspect again.

• It is not necessary to change the coolant after adding the tracer dye. When used properly, Dye-Lite
can remain safely in the vehicle until the coolant is changed.
