Radiator Repairs, Coolant Flush & Water Pump Replacement

A radiator performs the critical function of keeping a vehicle’s engine from overheating. If your car needs a radiator repair or radiator flush, a new water pump or fan, we’ll pinpoint the problem and do the repairs right the first time. There are a few issues that can lead to having your radiator either fixed or replaced.

Signs that your radiator needs repair are:
• Your vehicle overheats
• Steam comes out from under the hood of your vehicle
• Radiator coolant temperature gauge is elevated
• There’s a radiator coolant leak under your car (red, yellow or green fluid)

Preventative Maintenance:
• Inspect radiator for leaks
• Check coolant levels
• Pressure test cooling system
• Check radiator hoses
• Get a coolant flush every two years

Serpentine Belts & Hose Replacement

A big problem can happen very quickly if your vehicle’s belts and hoses are damaged. We recommend proper maintenance by having your vehicles belts and hoses checked regularly.

Engine Hoses – If a radiator hose develops a crack or hole, coolant will leak out and your car will overheat. Your vehicle may be undriveable.

Timing Belts – The timing belt is responsible for the timing of your engine, and if it’s stretched or damaged the engine can’t run properly. We recommend having your timing belt inspected every 9,200 or replaced every 62,000 miles.

Serpentine Belts – These belts are critical to the charging systems, air conditioning and cooling of your vehicle. While a serpentine belt is designed for long life, they do wear out eventually.

What our customers are saying..

“Last week I paid over $1200 for repairs related to coolant leaking from underneath the intake manifold on my 2010 Q5. So, why a 5 Star review? Because Brian took care of the extensive repairs at a fair price and is a genuinely nice person to work on your car! He is an Audi professional, and diagnosed my issues quickly. He replaced thermostat, heater pipe, and crankshaft breather valve as well necessary gaskets and seals. He also changed the oil and filter. While it is never pleasant to pay for unplanned car repairs, I know Brian does outstanding work and I trust him to keep my 12-year old car running great. Thank you, Brian!!” – Darlene S, Oak Park, CA / 5 Stars Yelp

Communication was good and he answered my questions and concerns throughout the process. I would take my car back here for future services and will recommend him to friends.” – Cary C., CA / 5 Stars Google Profile
