Exhaust
Leak repair
Leak repair pinpoints the exact source of an escaping fluid or gas — oil, coolant, fuel or exhaust — before deciding on the fix.
What it is and how we do it
Leaks can come from seals, gaskets, hoses, the radiator, a pump, the oil pan, the brake system or the exhaust. Each fluid has a different colour, smell and typical spot.
We clean, inspect under pressure, use fluorescent dye and, for gases, a smoke test and sensor readings. That way we find the real point, not just where the fluid pools.
Symptoms and when to come in
Stains on the garage floor, a dropping oil or coolant level, a sweet coolant smell, overheating, fuel odour or smoke in the engine bay all signal a leak.
Come in as soon as you notice a puddle or a falling level. Small leaks grow, and a fuel or brake leak is a safety matter.
Why it matters and why Mr. Service
Ignoring a leak can lead to overheating, loss of lubrication or brake failure. Finding the true source avoids replacing parts for nothing.
At Mr. Service we investigate the root cause, show you what we find and only repair after you approve the detailed quote. We serve domestic and imported cars of all brands, with a 3-month warranty on labour and a team that speaks Portuguese, English and Turkish in Chácara Santo Antônio.
