Quick answer
Cooling system repair at Fogg’s Automotive Fleet & Service Center in Scotia, NY, minutes from Schenectady, ranges from a $109–$179 coolant exchange to $600–$1,200 for radiator replacement. An overheating engine should be shut off immediately — continued driving can warp the head and destroy the engine within minutes.
What’s included
- Full-system pressure test — cold and at temperature
- Coolant condition, pH, and freeze-point testing
- Radiator, water pump, thermostat, and hose replacement
- Cooling fan and fan clutch diagnosis
- Manufacturer-correct coolant exchange with full system bleed
- Heater core diagnosis and replacement
Signs you need this
- Temperature gauge climbing above normal or into the red
- Sweet smell (coolant) outside or inside the vehicle
- Orange, green, or pink puddles under the engine
- Heater blowing cold air while driving
- Low-coolant warnings or visible loss between fill-ups
The full guide
Your engine produces enough heat to destroy itself in minutes — the cooling system is the only thing preventing that.
A $15 thermostat or a soft radiator hose can take out an $8,000 engine if it fails on the Thruway and you push on to Exit 26. Cooling problems are cheap when caught early and catastrophic when ignored.

We pressure-test the entire system to find leaks that only appear hot, test coolant condition and freeze protection — critical before a Capital Region January, when overnight lows in Scotia drop below zero — and repair or replace radiators, water pumps, thermostats, hoses, heater cores, and cooling fans on all makes and models, including the oversized cooling stacks on diesel and HD work trucks.
Modern coolants are engine-specific: the wrong formula corrodes aluminum components and gaskets from the inside out. We stock the correct OAT, HOAT, and IAT formulas and always match your manufacturer’s spec.
For fleet accounts
Coolant freeze point and condition are tested on every fleet PM and logged per unit, and hoses, belts, and radiators on vans and work trucks get flagged before the fall — an overheated engine is the most expensive downtime a fleet can buy.

Can I drive my car if it’s overheating?
No — pull over and shut it off as soon as it’s safe. Aluminum heads warp fast, and a warped head means a blown head gasket at minimum. A tow to Scotia from anywhere in Schenectady County costs far less than an engine.
How often should coolant be changed?
Most long-life coolants last 5 years or 100,000–150,000 miles, but coolant degrades quietly — it turns acidic and starts eating gaskets. We test it free with any service, so you only pay for an exchange when it actually needs one.
Why is my heater blowing cold air?
Usually low coolant, a stuck thermostat, or a clogged heater core — all cooling-system problems, and the low-coolant case can mean a leak that will eventually overheat the engine. Worth diagnosing in October, not during the first storm of a Schenectady winter.
