How Extreme Summer Heat Affects Your Car Engine (And How to Prevent Overheating)

The Danger of Summer Heat in Pakistan

Driving with A/C on in traffic during 45°C+ summer weather pushes engine temperatures close to 110°C. If your cooling system relies on tap water, it boils at 100°C, producing steam pockets that stop cooling the engine block. This causes rapid thermal expansion, warped cylinder heads, and expensive engine overhauls.

5 Essential Steps to Prevent Summer Overheating

1. Upgrade to High Boil-Point Engine Coolant

CRYO Radiator Coolant elevates the boiling point of your radiator fluid significantly higher than water, ensuring active heat transfer even in extreme traffic heat.

2. Check Radiator Cap Pressure Seal

A worn radiator cap loses pressure, dropping the fluid boiling point. Inspect the rubber gasket annually.

3. Flush Rust and Scale Annually

Rust scale acts as an insulator, trapping heat inside the engine block. Perform a full cooling system flush using distilled water before adding fresh CRYO coolant.

4. Inspect Radiator Cooling Fan Operation

Ensure your automatic fan relay triggers properly when idle in bumper-to-bumper city traffic.

5. Maintain Reserve Expansion Bottle Levels

Keep your coolant overflow tank filled between MIN and MAX marks with CRYO premixed formula.
