FAQ
How urgent is a small coolant drip?
More urgent than it looks. A seep that leaves a stain in the driveway is a system that cannot hold pressure, and pressure is what stops coolant boiling. Small leaks also fail suddenly when everything is hot and expanded. Topping it up week after week is not maintenance, it is a countdown.
Why is my heater blowing cold?
Usually the cooling system, not the heater. A low level, a thermostat stuck open, or a heater core blocked with sediment will all leave you with cold air. It is worth fixing quickly, because that same core sits behind the dash and replacing it is one of the longest jobs in the car.
Does stop-leak in a bottle work?
As a way to reach a shop, sometimes. As a repair, no. The same particles that plug a pinhole in the core also settle in the heater and the narrow passages in the engine, so you can trade a visible leak for a blockage nobody can reach. Tell the shop if you have used it.
Are the older shops in Oshkosh a safer bet?
[N_YEARS10] of the 24 shops here have been trading ten years or more. Radiator work rewards that, since the places that still recore and pressure test in house tend to be long-established and often run commercial vehicle work alongside cars.
