On this page you’ll find pro tools to nail coolant system like a pro. I own and use many of these tools and supplies and so I know they’re good.

Remote hose clamp tool made by Astro. Some coolant hose clamps are impossible to access without the use of this ingenious tool.

Ethylene Glycol coolant tester, easy to use and durable. Take a sample of the coolant, read the floating discs to check coolant strength, simple!

I love my refractometer because it does it all, measures both coolant types – ethylene glycol and propylene. Measures the freezing point of windshield washer fluid. Not only that, it measures the specific gravity of battery acid which indicates state of charge. It also measures Urea strength in DPF fluid.

Bar’s leaks is one of the best in the business. I wouldn’t use this on a fresh engine, I’d replace the gasket. But head gasket repair isn’t economical on older vehicles and Bar’s is the way to go. There’s a different potion for each type of leak you have, see the chart on the sales page. Try and match your type of leak to there chart for the best chance at success.

Leak down tester is great for finding worn rings, valves, leaking gaskets etc. You will need shop air or hobby compressor to operate this kit. Its easy to use, big gauges easy to read but most often your ears tell you where your problem is.

Perfect coolant system and rad cap test kit. Coolant leaks out and air sneaking into your coolant system are common causes of overheating, poor heat and intermittent heat. Vey often the issue is simple, a bad coolant cap or loose hose clamp. This little tool while not premium quality is perfect for the occasional user.

It pressurizes the system and the gauge and your ears will tell you if there’s a leak. Check that it suits your vehicle before pulling the trigger.

Prestone coolant system flush is a heavy duty coolant system cleaner. It cleans corrosion from the whole system – engine passage ways, radiator, heater core, auxiliary coolers like EGR, Turbo cooler lines, Alternator, Throttle bodies etc.
