Cooling & air conditioning
Cooling system flush
A cooling system flush removes rust, sludge and debris that reduce heat transfer and clog the radiator.
What it is and how we do it
Over time coolant loses its properties and leaves corrosion and dirt deposits that block the radiator cores and engine passages. The flush fully drains the system, clears the residue and refills with fresh fluid at the correct water-to-additive ratio.
We take the chance to inspect hoses, the reservoir cap and any signs of leaks, handing back a system that is genuinely clean and protected against future corrosion.
Symptoms and when to come
Dark or rusty-looking coolant, higher-than-normal temperature, uneven warming, and coolant that has never been changed. It is also recommended preventive maintenance at periodic intervals.
Why it matters and why Mr. Service
A dirty system runs hotter and speeds up wear on the pump, radiator and gaskets. At Mr. Service we use the fluid specified for each engine, check the rest of the system too, serve imported and domestic cars of all brands, quote before starting and back labour with a 3-month warranty. We speak Portuguese, English and Turkish.
