ABOUT US

Family-Owned. Community-Trusted.

Radiator Auto was started by Dave Kowalski, a lifelong gearhead who got tired of watching shops overcharge and underdeliver. He opened Radiator with a simple promise: treat every car like it's your own.

Today, our team of experienced technicians serves the greater Portland area with the same values Dave started with — honesty, quality, and respect for your time and budget. We're not a chain. We're your neighbors.

  • Family-owned and operated

  • Factory-level diagnostics

  • All makes and models

  • Written estimates — always

CUSTOMER REVIEWS

What Our Customers Say

  • “I've been bringing my cars here for 6 years. They're honest, fair, and always explain what needs to be done vs. what can wait. Rare to find a shop you can trust completely.”

  • “My check engine light came on during a road trip. They got me in same-day, diagnosed the issue quickly, and had me back on the road by afternoon. Lifesavers.”

    Sarah T.
    Sarah T.Honda Civic owner
  • “After the dealer quoted a big repair, I brought it here for a second opinion. Turned out I only needed a much smaller repair. They could have easily taken advantage.”
