Coolant Transfusion
Coolant doesn't last forever. Over time, the chemical inhibitors that protect your engine, radiator, and cooling system components from corrosion and scale break down — leaving your system vulnerable to rust, deposits, and damage. A professional coolant flush and transfusion at Dobbs Tire & Auto Centers removes degraded coolant and replaces it with a fresh mixture matched to your vehicle's specifications. Our ASE-certified technicians have been maintaining cooling systems since 1976, and with 150+ locations across the Midwest and South, expert cooling system service is always close by.
Coolant maintenance is often overlooked until a problem appears, but staying on schedule is one of the most cost-effective ways to protect your engine. Schedule your coolant service online, and financing is available
What is a Coolant Transfusion?
A coolant transfusion — also known as a coolant flush — is a service that drains and replaces the coolant circulating through your engine and cooling system. It goes beyond a simple drain-and-fill by using specialized equipment to flush residual old coolant from the heater core, hoses, and cylinder passages that a simple drain won't reach. The system is then refilled with a fresh coolant mixture at the correct concentration for freeze protection and boil-over resistance.
Modern vehicles use several types of coolant chemistry — OAT, HOAT, NOAT, and traditional green — and using the wrong type can shorten component life. Our technicians identify the correct coolant specifications for your vehicle and use the appropriate product.
Coolant Services We Offer
Complete Coolant Flush
Using flush equipment, we purge old coolants from the entire cooling system — including passages in the engine block, cylinder head, heater core, and hoses. This removes scale, rust particles, and degraded coolant chemistry that a drain-and-fill leaves behind.
Coolant Refill & Concentration Check
After flushing, we refill the system with the correct coolant type at the proper 50/50 or specified mixture ratio. We verify freeze protection and corrosion inhibitor strength using a refractometer or test strips.
Cooling System Pressure Test
As part of a thorough coolant service, we pressure-test the cooling system to identify any leaks in hoses, the radiator, or the water pump that might not be visible during a normal inspection.
Thermostat Inspection
While the cooling system is open for service, our technicians inspect the thermostat for proper operation. A thermostat that sticks open or closed can cause overheating or poor heater performance regardless of coolant condition.
Why Coolant Maintenance Matters
- Degraded coolant loses its corrosion inhibitors, allowing rust and scale to accumulate in the radiator and engine passages.
- Electrolytic activity in depleted coolants can attack aluminum engine components, gaskets, and water pump seals.
- Old coolant with improper freeze protection can freeze in cold weather, cracking the engine block or radiator.
- Coolant with weakened boil-over protection is less effective at preventing vapor formation and overheating under load.
- Maintaining fresh coolant on schedule is dramatically less expensive than replacing a corroded radiator or damaged water pump.
What to Expect at Dobbs
When you bring your vehicle to Dobbs for a coolant transfusion, your service advisor will verify the correct coolant type for your vehicle. Our technician will drain the system, flush it using equipment that reaches deep into the cooling circuit, refill with fresh coolant at the proper concentration, and pressure-test for leaks. We'll also inspect hoses and connections while the system is accessible. The service typically takes under an hour. A digital vehicle inspection is included, and financing is available.

Give your cooling system the fresh start it needs. Schedule a coolant transfusion at any of Dobbs' 150+ locations across the Midwest and South and protect your engine against overheating, corrosion, and freeze damage.
Most manufacturers recommend every 30,000 to 60,000 miles or every two to five years, depending on the coolant type. Long-life coolants may go longer between services, but the inhibitor package still degrades over time.
