Should coolant be filled to max line?

Should coolant be filled to max line?

The coolant should be between the max and min line when the engine is cold. It is perfectly normal for the coolant to expand and go above the max line when the engine is hot.

What happens when you overfill your antifreeze tank?

The purpose of the coolant recovery reservoir, or anti-freeze tank, is to allow for expansion and contraction of the coolant. Coolant, like most liquids, expands as it heats and this growth in volume must be accomodated.

Which is the best liquid antifreeze to use?

The most common variety of liquid antifreeze is an IAT formula, or Inorganic Additive Technology. ZEREX™ Original Green is an IAT coolant that has been used for decades and is a formula proven to provide unsurpassed corrosion protection.

What should coolant level be when engine is cold?

If you check your coolant level when the engine is cold, the coolant should be at or above the “minimum” or “fill” line on the transparent refill container.

When to drain the coolant from the engine?

The coolant level should be at the tank’s MAX or HOT line when the engine is hot, and lower when it’s cold. Yes. Draining out the coolant and refilling the system removes dirt and rust particles that can clog up the cooling system and cause problems in winter and summer. Why do I have to do this?

The purpose of the coolant recovery reservoir, or anti-freeze tank, is to allow for expansion and contraction of the coolant. Coolant, like most liquids, expands as it heats and this growth in volume must be accomodated.

Is the coolant in your antifreeze the same?

IS ALL COOLANT THE SAME? No. Different manufacturers use different colors to identify their own formulations. Although the basic ethylene glycol and water mix is the same, the remaining 3% is an additive blend that does differ across manufacturers and is not always universally compatible.

Do you have to put OE antifreeze in your car?

Unless you’re using universal antifreeze, of course, which is formulated to be compatible with all OE antifreeze. Be sure to add your vehicle to select the correct coolant for your vehicle before purchase. Did You Know? More is not always better.

Where is the maximum level for the coolant reservoir?

The reservoir is usually marked with a minimum and maximum level. The maximum level is below the top of the tank. That allows for possible expansion of the coolant in the system.
