We had them replace the engine on our 2002 Toyota Echo. It now runs like a charm, and they gave us a three year, 30,000 mile warranty on the engine and labor. We highly recommend Multnomah Automotive!

Why We’re the Team You’ll Feel Good Trusting
We know a cooling system isn’t the flashiest part of a vehicle, but it’s one of the most important. Your radiator quietly protects your engine every single time you hit the road, and when it’s not performing well, everything else begins to suffer. That’s why we give this system the attention it truly deserves. Our technicians take a highly detailed approach to every inspection, repair, and replacement. We start by understanding how your vehicle behaves, then we run careful diagnostics to spot any leaks, blockages, or performance issues before they grow. Whether you’re dealing with a sudden temperature spike or you simply want peace of mind before your next trip, we bring clarity, honesty, and real skill to every Radiator Service appointment. No confusing jargon. No unnecessary work. Just solid support, accurate solutions, and a refreshing level of care that makes auto service feel stress-free in Portland, Oregon.

Signals Your Car Is Asking for Some Cooling Attention
Your car may not talk, but it absolutely communicates, especially when the cooling system starts losing its strength. A radiator on the verge of trouble often gives subtle hints long before a breakdown, and catching them early is the easiest way to protect your engine. These signs might seem small in the moment, but they’re your engine’s way of asking for a Radiator Service. Listening early saves you from bigger, more expensive issues later.
Temperature gauge climbing higher than normal
A temperature gauge may be climbing higher than normal due to low coolant levels, a broken thermostat, a failing water pump, a clogged radiator, a cooling fan that isn’t operating properly, or a blown head gasket.
A puddle or drip of coolant under the front of your vehicle
Coolant puddles under the car after parking may be caused by a leaking radiator, cracked or loose hoses, a faulty water pump, a damaged heater core, or a loose or failing radiator cap allowing coolant to escape.
A sweet, syrup-like smell near the hood
This smell may indicate a coolant leak from the radiator or hoses, overheating engine components, leaking antifreeze dripping onto hot parts, or even electrical wiring insulation beginning to burn.
Heater taking too long to warm up or blowing uneven heat
Usually this is due to low coolant levels, a thermostat stuck open, air pockets in the cooling system, a partially clogged heater core, or a malfunctioning blend door actuator affecting airflow control.

The team here is fantastic. We had car troubles and they were fast and very honest about our options. They took detailed notes and photos about nest steps on repairs for our vehicle. We had such a great experience that they are now our permanent mechanics.
Best place to take your car in Portland. Always makes time for you and does a great job and is affordable. Can trust them to do what you need and never over sells or over charges.
I had my brakes replaced here based on a recommendation from a coworker. They were helpful, honest, and got it done in one day!
My car’s tires blew out right near their shop, and they were super helpful in getting new tires in and replacing them within one day. Really helpful, and professional.
These guys are FAST! I needed an oil change and a catalytic converter shield installed on my Prius. They were pretty busy when I came to the shop by they still turned it around in a couple hours and gave great service. Shout out to Jason and his team, keep it up!
Jason was so kind and gave me great advice even though my car was at another shop. He’s honest and sincere, and knows how to get his customers back on the road.
During the last year I have taken my Dodge to Multnomah Automotive for both a major engine repair and a standard oil change. I felt respected and cared for both times and highly recommend this friendly neighborhood shop.
Jason helped fix multiple issues in my Toyota for $2000 less than what the dealer wanted. Jason and his team worked quickly and communicated clearly about issues that needed to be addressed. As long as Jason is there we’ll be bringing in our cars for service.
These guys are awesome! I had a problem with a battery install, brought the car back and they replaced the battery free of charge. Great communication, helpful advice too!
Amazing service and great management. Jason was awesome and quickly found the issue in my tire. I was in and out in about 10 minutes and for only $20. 10/10 auto shop experience
I love this place. The owner is straight up. This is an awesome shop. My repair was concise accurate. I trust them implicitly and it’s a drive for me AAA rated… Check them out Jason has your back.
Staff was incredibly friendly and went above and beyond to make sure I was taken care of, work was quality and efficient. Will be returning my business here going forward!
