5 Signs You Need Cooling System Service
Engine Overheating
Temperature gauge climbing into the red or steam from under the hood means your cooling system needs attention now.
Low or Leaking Coolant
Puddles of green, orange, or pink fluid under your car, or a coolant warning light, point to a leak in the radiator or hoses.
Sweet Smell In or Outside the Car
A sweet, syrupy smell often means coolant is leaking onto hot engine parts or into the cabin heater core.
Heater Blowing Cold Air
If your heater suddenly stops working, low coolant or a failing water pump is often the cause.
Discolored or Sludgy Coolant
Coolant that looks rusty brown or has debris in it has broken down and needs to be flushed before it damages your radiator.

"I came to get my brakes done. Not only was the staff great, Irma offered to drive me back home to save me money on a Lyft. They made suggestions on what needed to be done and were willing to work with me without making me feel pressured. They genuinely made me feel like they were looking out for my best interest."
"Dennis is very knowledgeable, patient, and professional. I had an estimate from the dealership before coming here, and he handled everything smoothly from start to finish, explained what was needed, and made the whole process easy and transparent. Carlos was friendly, honest, and quick."
"Great guys, fast service! Dennis took good care of us here and made sure everything was perfect on the oil change. Will be back with my other vehicles."
