As a GMC Sierra 2500HD owner, it’s essential to understand the different types of coolant available and their proper level ratio.
The most commonly used engine coolant is DEX-COOL, a long-lasting orange or red-coloured ethylene glycol-based fluid that offers better protection against corrosion than regular green antifreeze.
Always use a 50/50 mixture of clean water and DEX-COOL coolant for the best engine performance when adding coolant. This mixture provides freezing protection down to -34°F (-37°C) and boiling protection up to 265°F (129°C).
To maintain your vehicle’s optimal performance, keep an eye on your coolant levels regularly by checking the reservoir tank every few months or after long drives.
Location Of Coolant Reservoir
You need to locate the coolant reservoir to add coolant to your GMC Sierra 2500Hd. This container is an essential component of your truck’s cooling system and can be easily found near the front of the engine bay on the passenger side.
It is usually a see-through plastic tank with a radiator cap that allows easy access when adding or checking coolant levels. Identify the right one, as other fluid reservoirs may be nearby.
Once located, it’s important to check that the coolant level is between minimum and maximum marks before topping it up with a 50/50 mixture of clean water and DEX-COOL antifreeze.
Remember never to use tap water or mix different types of coolants, as this can damage your engine in the long run.
How To Check And Add Coolant To GMC Sierra 2500HD
To check and add coolant to your GMC Sierra 2500HD, first identify the coolant reservoir located near the front of the engine bay on the passenger side, then check the coolant level by looking at the markings on the side of the reservoir and adding a 50/50 mixture of clean water and DEX-COOL coolant if necessary.
Identifying The Coolant Reservoir
Locating the coolant reservoir in your GMC Sierra 2500HD is crucial to adding or checking the coolant level. It’s typically situated on the vehicle’s passenger side, close to the front of the engine bay.
You can easily identify it by looking for a translucent plastic jug with a radiator cap attached to it. The jug is labelled “Engine Coolant” with markings indicating minimum and maximum levels for proper fluid volume.
Ensure you only add coolant when the engine is cool, as opening it while hot can result in severe burns from escaping steam.
Checking The Coolant Level
Locate the coolant reservoir to check the coolant level in your GMC Sierra 2500HD. The reservoir is typically located on the passenger side of the engine bay, near the front of the vehicle.
If your coolant level is low, add a mixture of clean water and Dex-Cool coolant until it reaches or slightly exceeds its recommended level.
