Radiator Service

Feel the Difference of Reliable Cooling

When your engine stays calm, your whole drive feels smoother, and our team is here to keep your radiator steady, reliable, and ready for anything.

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.

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.

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.

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.

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.

This auto shop was great! They were so nice and helpful in everything they did. They diagnosed my problem quickly and replaced my battery very fast. Very inexpensive for the job performed and gave me quite a discount! Choose these guys they are the way to go!

J Delaney

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!

Alec J

Had my starter go out. They were able to diagnose and replace within two days despite being extremely busy. They also provided a full inspection without being pushy or trying to upsale. Good honest work. Thanks!

Spencer Short

Definitely recommend Multnomah Automotive for those searching for local auto care needs. They are friendly, honest, communicative, and work til they find a solution for the problem. Very happy to have them around for our ever-evolving car problems. Thank you!

Julie Lau

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.

Signa Haygarth

Good, honest service. Reasonable prices. Jiffy Lube is right across the street from me, but I still make the 20 minute trip to Multnomah Automotive because of those qualities.

Alex

I had a really great experience here. Service was friendly and explained everything clearly and thoroughly. They also always maintained good communication throughout and the service was timely. I definitely see myself as a repeat customer.
