Cadillac Radiator Replacement Details

The radiator's job is to allow heat to be removed from the engine. As hot coolant passes through the radiator it is cooled before returning to the engine, where it absorbs heat and returns to the radiator. This cooling process keeps the engine from overheating.

Common Symptoms:

  • Coolant may leak or boil over
  • Temperature gauge may get really high
  • Illumination of the engine temperature warning light
  • Engine may run hot or overheat

What the Mechanic Should Do:

  • Replace the thermostat and the radiator cap along with the radiator. The radiator hoses should also be replaced if they show signs of age or wear.
  • The entire cooling system should be inspected and tested when the radiator is replaced
  • Most radiators are made of metal and plastic. The plastic parts can become brittle and crack over time, leading to radiator replacement.

They were very thorough and gave me estimates of everything to be done before doing anything. I know several people that work there and I trust them at work and outside of work.

by - Verified Customer August 19, 2015

They fixed my car for like nine hundred dollars less than the dealer wanted to charge me. The offered to come get me and bring me back to work. They had my car done on time and didn't over charge me and all they are a very reasonable place. Very customer felt and very good.

They are easy to deal with.

by - Verified Customer May 19, 2015

I have had no complaints, any time I do work, there are no hidden fees, your bill is never more than projected. They email break downs so you can see your totals what they are. I have had to where I needed a ride, and they dropped it off to me, which was very nice. I have nothing but good things, they are polite, their office is actually clean. They also keep my vehicle inside.
