Old or contaminated coolant lets corrosion attack your radiator, water pump, and heater core — and lets your engine run hotter. A proper flush restores the cooling system and protects an expensive engine. Done in about an hour.

When to Bring It In
Signs your cooling system needs attention
🌡️ Temperature gauge climbing
If the gauge creeps above normal — especially in traffic or on hot days — your cooling system is struggling. Worn coolant, a failing thermostat, or a weak water pump are common causes.
🍯 Sweet smell from engine bay
Ethylene glycol in coolant has a distinctive sweet smell. If you can smell it, you have a leak — usually from a hose, the water pump, or the radiator. Get it checked before the system runs dry.
💧 Coolant on the ground
Green, orange, or pink puddles under your car are coolant. Even a slow leak should be diagnosed quickly — running low can cause overheating that destroys head gaskets.
🟤 Rusty or muddy coolant
Healthy coolant is bright green, orange, or pink (depending on type). Brown, rusty, or muddy coolant means corrosion is happening inside your cooling system. Flush immediately.
❄️ Heater not blowing hot
If your cabin heater is weak even after the engine warms up, the heater core may be clogged with sediment — often a sign coolant is overdue for a flush.
📅 Past manufacturer interval
Even if everything seems fine, follow your manufacturer's schedule. Most call for a coolant flush every 30,000-60,000 miles or 3-5 years.
Coolant Flush FAQ
Common questions, straight answers
How much does a coolant flush cost in Concord, CA?
Coolant flush at Super Station Concord starts at $150. This includes draining the old coolant, refilling with the correct manufacturer-spec coolant, bleeding air from the system, and a pressure test for leaks. Prices vary by vehicle — European cars and trucks with larger cooling system capacities are priced higher.
How often should I flush my coolant?
Most manufacturers recommend a coolant flush every 30,000 to 60,000 miles or every 3-5 years. Newer extended-life coolants can go up to 100,000 miles. We test your coolant's condition and acidity at every visit and recommend a flush only when actually needed.
What are signs I need a coolant flush?
Common signs include engine running hotter than normal, sweet smell from the engine bay, coolant that looks rusty or muddy instead of bright green/orange/pink, the temperature gauge climbing in traffic, and any low-coolant warning light. A coolant flush is also recommended preventively per manufacturer schedule.
Will a coolant flush fix overheating?
Sometimes. If overheating is caused by old, contaminated coolant or sediment in the cooling system, a flush can solve it. But overheating can also signal a failing thermostat, water pump, radiator, or head gasket. We diagnose the root cause first — never just flush and hope.
What kind of coolant do you use?
We use the exact coolant your manufacturer specifies — OAT, HOAT, IAT, G12/G13 for VW/Audi, Dexcool for GM, Toyota Red/Pink, Honda Blue, Mercedes/BMW spec, etc. Mixing coolant types causes gel formation and corrosion, so we never substitute.
