A winter van check is six things and takes about twenty minutes on a dry afternoon: the battery, the tyres, the screen and wipers, the coolant and antifreeze, the lights, and the doors and seals. Do them before the weather turns rather than after, because every one is a five-minute job in October and a lost morning in December. None of it needs a workshop or tools you do not already own, and a van that starts and stops properly on the first cold morning has already paid you back.
We prepare used vans in Haydock, St Helens, and this is the list we work through ourselves. These guides sit under our Van Guides hub, alongside Van Running Costs.
The winter van checklist, in one pass
Work through it in this order — it goes from the thing most likely to strand you to the thing most likely to annoy you.
- Battery. Cold weather does not break batteries; it finds the one that was already marginal.
- Tyres. Tread depth, pressures laden and unladen, and condition including the sidewalls.
- Screen, wipers and washers. Blades, screenwash concentration, and a working heated screen or demister.
- Coolant and antifreeze. Level and strength, and whether the heater actually gets hot.
- Lights. Every bulb, and the lenses cleaned. Dark mornings double the time your lights are working.
- Doors, locks and seals. The load area especially, which is where damp and frozen locks live.
One honest note about used vans, and it is the reason this list is worth doing rather than assuming. Around eight in ten of the small vans we buy in have needed money spending on them before we would put them back out. That is not a comment on any make — it is what a working vehicle looks like after a few years of somebody’s livelihood. The items above are exactly the ones that get deferred, and winter is when a deferred item stops being deferrable.
The battery
The single most common reason a van does not start on a cold morning, and the most predictable. Cold thickens the oil so the engine is harder to turn, and it reduces what the battery can deliver at the same time. A battery that has been quietly weak all summer is fine at fifteen degrees and useless at minus two.
The signs arrive weeks early: slow, laboured cranking, headlights dimming noticeably while starting, dashboard electronics resetting. Short journeys make it worse, because the alternator never gets long enough to put back what starting took out — a van doing local drops all week can be losing charge every day.
Have it tested rather than guessed at — most garages and factors will do it free in a few minutes, and it is the difference between replacing a battery on your terms in November and on a verge in January. Our guide to checking a used van’s battery health takes it properly: how to test, what the readings mean, how long one should last. This page keeps it to one item.
Tyres: tread, pressure and what the law actually says
The legal minimum tread depth is 1.6mm across the central three-quarters of the tyre, around its entire circumference. That is the legal floor, not a target — grip in cold, wet conditions falls off well before you reach it, and a heavily loaded van needs more of it than a car does.
Three checks, all free:
- Depth, across the width and around the tyre, not just where you can see it. Uneven wear points at pressures or alignment, and is worth chasing before winter rather than after.
- Pressure, cold, against the plate in the door frame. A van usually has two sets of figures, laden and unladen. Running unladen pressures with a full load is the commonest mistake there is, and it costs grip, fuel and tyre life at once.
- Condition. Sidewall cuts and bulges, perished rubber, and mismatched tyres across an axle. A perished tyre with plenty of tread is still a bad tyre.
Tyres are also the most common MOT failure item there is, so this check pays twice — what vans actually fail their MOT on covers the rest of that list. And when the weather does turn, the Highway Code’s rules on driving in adverse weather are the authority on stopping distances and what is expected of you.
Screen, wipers and washers
The least costly section on this page, and the one that most reliably ruins a morning.
Blades perish in summer sun and tear on frozen glass. If they judder, smear or leave a band at the top of the sweep, replace them before the first frost. Lift them off the glass overnight if you expect ice, or cover the screen — pulling a frozen blade off a windscreen is how a good blade becomes a bad one.
Screenwash matters more than people think. Plain water freezes in the bottle, the pipes and the jets, and a van with no washers on a salted motorway is dangerous within a mile. Use a proper concentration for the temperature rather than topping up with water and hoping.
The demister and heated screen are the third leg. If the screen clears slowly, the air conditioning is usually part of the answer — it dries the air, which is why it belongs in a winter check and not just a summer one. The air-conditioning faults that show up most on used vans covers what to test and what a slow demist is telling you.
Coolant, antifreeze and the cold-start check
Antifreeze is not only about freezing. It carries the corrosion inhibitors that stop the inside of the engine and radiator rusting, and those wear out on a schedule whether or not it has been a cold winter. Level and strength are two different checks, and strength is the one nobody does.
Check the level cold, against the marks on the expansion tank. If it needs topping up more than occasionally, that is a leak to find rather than a habit to adopt. Use the coolant type the van specifies; mixing types makes an expensive problem.
Then do the cold-start check, first thing: does it start promptly and settle, does the heater get hot within a few miles, does any warning light stay on longer than it should? A van that starts sweetly from cold is telling you most of what this list is looking for.
The load area and the doors
The half of a van that a car checklist never covers, and where winter does its quiet damage.
- Door seals. Perished or torn seals let water into the load area, and a damp load area rusts from the inside. Check all round, sliding door and rear doors included.
- Locks and mechanisms. Sliding door runners and rear catches seize and freeze. A light lubricant on both before winter is five minutes well spent.
- The load floor. Lift the ply and look. Standing water under a floor is a common cause of corrosion on a working van, and it is invisible from above.
- Drainage. Clear leaves and grit out of the scuttle and the door drains, so water goes where it is designed to go.
Salt is the other winter enemy. A van that works on gritted roads all week collects it underneath, and the best defence is dull: wash the van, including underneath, when you can. If you are buying at this time of year, the underside is the first place to look — what to check when buying a used van covers that inspection properly.
What to carry in the van from November onwards
Short list, all of it cheap, none of it clever.
- A scraper and de-icer — in the cab, not the load area behind a frozen door.
- A torch that works, and a phone power bank.
- Jump leads or a jump pack, and a rough idea of where the battery actually is on your van.
- A high-visibility jacket and a warm coat you would not otherwise wear.
- A tow rope, and a small shovel if you work anywhere rural.
- Screenwash concentrate, because the day you need it is the day the bottle is empty.
The other winter habit costs nothing at all: leave more time and more space. Winter driving tips for van owners in the North West covers the driving side, which is a different job from this one.
One last piece of timing. If the MOT falls in the winter months, check the record before booking — the DVSA’s MOT history service shows every previous advisory free, and the guidance on when an MOT is due covers the dates. Last year’s advisories are this year’s failures, and they are usually on the list above.
Common questions
What should I check on my van before winter?
Six things, in this order: the battery, the tyres, the screen and wipers, the coolant and antifreeze, every light, and the doors and seals. It takes about twenty minutes on a dry afternoon and needs no tools you do not already own. Doing it in October rather than December is the whole point.
Why does my van struggle to start in cold weather?
Cold thickens the oil so the engine is harder to turn, and reduces what the battery can deliver at the same time. A battery that was quietly weak all summer is fine at fifteen degrees and useless at minus two. Short local journeys make it worse, because the alternator never replaces what starting took out.
What tread depth do van tyres legally need?
1.6mm across the central three-quarters of the tyre, around its whole circumference. That is the legal floor rather than a sensible target — grip in cold, wet conditions falls away well before you reach it, and a loaded van asks more of a tyre than a car does. Check condition and pressures too.
Do I need winter tyres on a van?
Not legally, and most working vans in this country run all-season or summer tyres the whole year. They genuinely help if you work rural roads or steep ground in bad weather. For most drivers, tyres in good condition at the right pressures matter far more than which type is fitted.
Should I warm the engine up before setting off?
Not by sitting on the drive — a stationary engine warms slowly, burns fuel for nothing and is illegal to leave idling unattended on a public road. Clear the glass properly, then drive gently until the temperature comes up. That warms engine, gearbox and brakes together, which is what you want.
