Product Details

The Four Seasons 69087 is a 1 oz. bottle of fluorescent dye designed specifically for automotive cooling system leak detection. This professional-grade diagnostic tool helps technicians and DIYers quickly identify the exact location of coolant leaks in radiators, hoses, heater cores, water pumps, and fittings.

How It Works:

  • Add the fluorescent dye to your cooling system and allow it to circulate with the coolant during normal operation
  • The dye escapes with the coolant at all leak sites throughout the system
  • Using a UV leak detection lamp, scan the cooling system components in a darkened area
  • Leaks will glow bright yellow-green under UV light, pinpointing the exact location of even the smallest leaks

Key Features:

  • Convenient 1 oz. bottle size provides the right amount for most passenger vehicles
  • Compatible with all conventional coolant types
  • Detects multiple leaks simultaneously in a single application
  • Remains active in the system for ongoing leak detection
  • Professional-grade formula from a trusted automotive climate control brand

Four Seasons, part of the Standard Motor Products Temperature Control Division, has over 50 years of experience in mobile air conditioning and cooling system components. This fluorescent dye provides a reliable, cost-effective method for diagnosing cooling system leaks before they lead to overheating or engine damage. A UV leak detection lamp (sold separately) is required to visualize the dye.

I recently needed head bolts for my 408 stroker motor that I'm building. I searched the Internet and Autoplicity had the ARP Head Bolts that I needed. Great price and quick shipping. Will definitely buy from again!!

not till i recieve package

Mazda cargo mat for the CX-9 SUV came within 1 week. Mat fits perfectly; just as described. Autoplicity had the best price listed for this product; we are very pleased.

Very satisfied! My intake shipped on Friday and I received it on Tuesday. Not only super fast shipping, but a great deal to boot!

very good

I have searched the internet for the best pricing on auto accessories and ended up at Autoplicity. I tried everything to negotiate prices with some supplies and still got the best pricing usins Autoplicity without any hassles or delays. My invoice number 9314 shows that I got a great deal thanks to Autoplicity. I will be a returning customer for my future purchases.

Almost a perfect score! I was pleased with the customer service but knowledge about their products warranties was lacking. Other than that, the representative that I spoke with on the phone was great. He was friendly and had a good overall knowledge of the products I was asking about. Pointed me in the right direction because I couldn't be happier with my bike rack. They had the best prices, lowest shipping costs, and my order arrived a day early. Great website to work with. I will definitely be doing business again and spreading the word about Autoplicity.com.

I got all of my parts in and where happy with them. The website is about the cheapest around. Something about them really gives me a good feeling. :)
