Frequently asked questions
Having your coolant professionally changed ensures that any rust or deposits are removed and this stops components in the engine from getting clogged up.
Your engine can seize in extreme weather conditions, so you should always book a coolant change at the appropriate intervals or if you notice an issue.
In short, keeping up with regular coolant changes prevents engine wear and will keep your car running smoothly.
Once you’ve chosen your garage, you deal with them directly from start to finish, paying only after the work is complete – giving you full peace of mind.
Some mobile technicians may request some commitment or payment upfront to cover the costs of them coming out to you.
You can change your filters anytime if one factor is more important to you than others – full transparency, full control.
Antifreeze should be added to the container as soon as possible.
You should take care not to overfill the reservoir with tap water as this could damage the larger cooling system.
Whilst adding a little water to coolant shouldn't cause any major damage, adding too much can lower its boiling point and make the coolant ineffective.
Generally speaking, though, you should either use engine coolant as a pre-mixed solution or mix a 50:50 ratio of distilled water to antifreeze yourself - you should refer to the instructions on the antifreeze if you aren't sure how much to use, as the required ratio may not always be exactly 50:50.
