Busbee's Biggest Tip to Save Your Commercial Truck This Summer

Checking the coolant in your radiator is the single most important thing you can do to help your medium or heavy duty box truck to not overheat in the hot temperatures this summer.

When checking your coolant, it's so important that you physically check the radiator level when the engine has been cool for at least 2-3 hours.

Belive it or not, you can't just look at the radiator reservoir jug and assume it's telling you the truth. Just because the reservoir jug may be full, does NOT mean you have coolant in the radiator.

This vacuum reservoir type system counts on a vacuum to draw water out, and if you get a hole in the cooling system somewhere, the vacuum system will not work and you may never know just by looking at the reservoir jug. With a hole in the hose or somewhere, it can't draw water out and your truck will run hot despite the full jug.

This will ruin a very expensive motor and causes thousands of dollars in damage within just a few minutes.

The best way to avoid this problem, is to lift the cab before you crank in the morning when the engine has been cool for at least 2-3 hours and physically check the radiator level.

DO NOT OPEN THE RADIATOR UNTIL THE ENGINE HAS AT LEAST SEVERAL HOURS COOLING TIME.  Open the radiator, on a cold engine, very slowly.  If you open the radiator on a warm or hot engine, you will risk getting seriously burned.

This is especially serious on your Mitsubishi Fuso, UD, Hino & Isuzu box trucks because they are much more expensive than cars.
