A properly sealed coolant cap may seem like a small detail, but it’s crucial in preventing engine overheating and costly repairs. When the cap isn’t secured or the seal isn’t tight, your cooling system can’t maintain the necessary pressure, leading to coolant leaks or evaporation. Without enough coolant, the engine is left vulnerable to extreme heat, which can cause severe damage, such as warped engine parts, blown head gaskets, or even a cracked engine block. If left unchecked, this can cause severe damage to vital engine components, leading to costly repairs that could easily exceed thousands of pounds. A small oversight can quickly become a major headache!
To prevent such issues, it’s important to always double-check your coolant cap after any maintenance work or service. A quick inspection can save you from major engine trouble. If you find that your cap is worn or damaged, it’s essential that you don’t wait and replace it immediately.

So How do I Check the Cap?
1 . Insure that the engine is cool to avoid burns from hot coolant.
2 . Open the bonnet and locate the coolant reservoir.
3. Inspect the cap to see if it sits flat and aligned without any visible gaps then twist the cap clockwise until it is snug and tight.
If the cap feels loose or doesn’t secure properly, it may need to be replaced to maintain proper pressure in the cooling system.
