Keeping on top of coolant and antifreeze is one of the easiest ways to protect your Mercedes CLA35 AMG from expensive engine damage. Quality coolant does more than just stop the system freezing in winter, it also raises the boiling point, helps control cylinder head temps under load, and contains corrosion inhibitors that protect alloy blocks, radiators, heaters and pipework over the long term.
If you drive your Mercedes CLA35 AMG hard, see regular motorway miles, spirited B-road runs or the odd track day, your cooling system works overtime. Old, contaminated coolant loses its protective properties, can sludge up in narrow galleries and may allow hotspots that lead to detonation or head gasket issues. Refreshing the system with the correct spec antifreeze mix is a simple reliability mod that supports all your other performance upgrades.
In this Coolant & Antifreeze section you will find premium formulas matched to OEM specifications, plus motorsport-focused options for harsher conditions. Always check your vehicle’s requirements, especially when choosing between traditional glycol mixes and modern OAT / HOAT coolants, and never randomly mix types. Paired with a healthy radiator, thermostat and water pump, the right coolant helps the engine in your Mercedes CLA35 AMG run consistently, giving you stable performance, quicker recovery between pulls and solid peace of mind every time you lean on the throttle.
