Service 23 | Coolant Flush
Old, contaminated, or insufficient coolant can cause corrosion, poor heat transfer, and costly overheating. We drain and flush the cooling system, refill it with the correct coolant mixture, pressure-test for leaks, and inspect the radiator cap, hoses, thermostat, and related components.
Coolant is the most neglected fluid in the car and the one that does most damage when it fails. Every system is pressure tested, vacuum filled and heat cycled before it leaves.
Our process
From the first call to the moment your car is returned, the process is deliberately simple. You approve the work and the price before anything is touched, so there are no surprises when you collect the car.
Book in under a minute and we collect the car from your home or office. No lift to arrange and no waiting room.
Certified technicians run a full diagnostic scan and send you the readout with a fixed quote. Nothing is touched until you approve it.
The work is carried out to manufacturer procedures, road-tested twice, then the car is washed and returned to your door.
What we do
Coolant is the most neglected fluid in the car and the one that does most damage when it fails. In 45°C heat, overheating escalates quickly.
Why A to Z
Every car gets a full diagnostic scan before we quote. You see the readout and the fault codes whether you go ahead or not.
We collect from your home or office and bring the car back when it is done. No lift to arrange, no waiting room.
A workshop near you and shorter waiting times. Your service history follows you between every branch.
Warning signs
Overheating is the fastest way to turn a small fault into a rebuild. These are the warnings that come first.
Coverage
Petrol, diesel and hybrid, from everyday family cars to performance and prestige marques. If your car is not listed, call and ask — the list is not exhaustive.
FAQs
Most manufacturers specify every four to five years, but in this climate we suggest checking condition annually. Coolant loses its corrosion inhibitors over time even if it still looks clean.
In an emergency to get home, yes. But water alone has no corrosion protection and a lower boiling point, so it must be replaced with correct coolant as soon as possible.
At speed there is airflow through the radiator. In traffic you depend on the cooling fan and a clean radiator core. Blocked fins or a weak fan shows up exactly then.
No. Pull over and let it cool. Continuing to drive an overheating engine warps the cylinder head, and that turns a hose repair into a head gasket job.
What we do
Everything below is done in our own workshop by our own technicians, with a written quote before any work starts.
Old coolant drained, system flushed and refilled with the correct specification fluid.
System evacuated and filled under vacuum so no air pocket is left behind.
Cap and system tested to find leaks that only appear when hot and pressurised.
Replaced together where access makes it sensible, with a new gasket every time.
Blocked radiators, perished hoses and cracked expansion tanks replaced.
Combustion gas testing where overheating suggests the gasket has already gone.
Why us
Mixing coolant types causes gelling that blocks the radiator. Filling without a vacuum leaves air pockets that cause localised overheating.
