Winter Car Checklist: What Brierley Hill Drivers Should Check Before December

15 October 2025 · 6 min read

Battery — the most common winter failure

Cold temperatures significantly increase the current required to crank an engine — and simultaneously reduce the battery's ability to deliver that current. A battery that copes adequately in October may leave you stranded on a hard January morning. Batteries typically last four to five years, and any battery over three years old is worth having tested before the cold sets in.

Signs a battery is struggling include slow cranking on start-up, warning lights that flicker briefly before the engine fires, or the car needing multiple attempts in the morning. We can carry out a battery load test in around ten minutes that shows whether the battery has enough reserve capacity to handle winter reliably. If it does not, replacing it before you are stranded is significantly less inconvenient than the alternative.

Tyres — tread depth and pressure in cold weather

Tyre pressures drop naturally as temperatures fall — approximately 1 PSI for every 10-degree Celsius drop in ambient temperature. Check pressures when the tyres are cold, before any driving, and inflate to the manufacturer-specified figure. Check all four tyres and the spare if you carry one. Under-inflated tyres in cold and wet conditions reduce grip and increase braking distances.

Tread depth matters more in winter. The legal minimum is 1.6mm, but braking performance on wet roads degrades noticeably below 3mm. Check depth across the full width of each tyre — uneven wear across the width can indicate alignment or suspension issues worth investigating before the weather deteriorates. The road network around Brierley Hill and across the Black Country can be particularly challenging in ice and standing water.

Coolant, screen wash, and wipers

The antifreeze concentration in the coolant prevents the engine block from cracking in a hard frost. Concentration drops over time as the system is topped up with plain water. Check the antifreeze level with a simple tester — protection should extend to at least -15 degrees Celsius for UK winter conditions. If it tests above that threshold, the coolant needs replacing or the concentration topping up.

Screen wash concentration is easy to overlook. Summer-mix screen wash freezes in the pump and jets and can crack them. Switch to a winter-concentration screen wash before the first frost. Replace wiper blades if they are leaving streaks or chattering — new blades cost very little and make a significant difference in heavy rain and low-visibility winter driving conditions.
