Why Get a Radiator/Coolant Flush?

We’ve all felt helpless while stranded on the side of the road with your vehicle hood up and your vehicle steaming. Maybe your vehicle has failed to start in the dead of winter because the fluid in your engine was frozen. Or maybe the engine putters and fails to respond despite all of your might.

A properly functioning cooling system circulates antifreeze/coolant through the engine and radiator, helping reduce heat levels produced by your vehicle’s engine. When the cooling system isn’t functioning properly, the temperature of your engine can get hot enough to damage itself (heads can warp, gaskets can blow, engine fails). Now we’re talking costly repairs.

An antifreeze/coolant flush and fill at regular intervals can help prevent overheating, freezing and premature cooling-system corrosion. Our Otobots mobile mechanics will examine your radiator and engine cooling system. Then, old antifreeze/coolant is removed from your radiator and replaced with new antifreeze/coolant per your vehicle manufacturer’s recommendations.

Having your radiator inspected by a certified Otobots technician can save you a lot of money and time spent on the side of the road. Schedule an appointment with an Otobots mechanic today for a radiator/coolant flush today!

Still not sure if your vehicle’s coolant needs servicing? Read our FAQ’s:

My temperature gauge is off the charts – is this a good indicator that my coolant system needs to be checked?

The first sign that there is an issue with the cooling system in your vehicle will often come from the temperature gauge. If your vehicle has been running consistently warmer or has recently begun having issues with overheating, there is likely an issue with the cooling system. Even if your vehicle is not overheating but has been running at the higher end of the operating range, there may be an issue. If your vehicle is running with the temperature gauge in the red, it is overheating. Pull over and shut off the vehicle.

I see a puddle under my car where the engine sat – that can’t be good, can it?

Leaks are a common issue in coolant systems. If you spot a puddle beneath your vehicle, there’s a chance that it may be the result of a coolant leak. Touch the puddle with a finger, then smear it onto a blank white sheet of paper. Oil is often brown or black, water from the air conditioner will be clear, and coolant will likely be green, pink or orange. A leak in your coolant system can cause it to fail to maintain proper temperature in the engine.

What are some of the common issues with alternators reported by your technicians?

The most common alternator problems include worn carbon brushes, worn contact rings (the two copper cylinders at the back of the rotor) and a failed voltage regulator. Bad outer and inner alternator bearings (large and small silver cylinders in the cutaway image above) can produce a whining noise. When the alternator is rebuilt, the bearings, voltage regulator, brushes and some other parts are typically replaced with new ones.
