TRACER Spectronics TP39400601 Rite-Blend Extended Life Coolant Dye: Enhancing Water Based Fluids Review

This dye kit had me impressed from the start! Its intuitive packaging made it incredibly easy to use and the high-quality dye offered excellent results. The kit also features a bright LED bulb, which made inspection under the hood an absolute breeze. While the kit's instructions could've been clearer, it was still relatively easy to use, even for beginners. Overall, the Tracer Spectronics Rite Blend Extended dye kit is an outstanding tool for anyone who wants to quickly and safely diagnose…

Tracer is my choice for coloring and this product does the job. The only reasons I gave them 4 stars instead of 5: (1) The listing is wrong (says "Ford Approved" when their catalog says "GM Approved"). They need to update their lists. (2) They, like other dye manufacturers, must indicate on the product the specific absorbance wavelength (in nM) of the dye so that users can use the correct light to work with the dye. Long wavelength (as listed) is by definition a fairly broad range (315-400nM)…

I knew coolant was leaking but could not even realizing it was hot, I poured paint into the coolant reservoir and drove around to make sure the engine was hot and coolant was flowing. Using the leak detector's LED display, I found a drop of "red-hot coolant" on the skid plate and followed it through the engine until I found a leak behind the water pump. Saved by throwing pieces at the problem.
