Stewarts Radiator does quality work for an affordable price. I plan to continue doing business with Wally and his team in the future.

Imagine waking up to a flooded house! That's the kind of nightmare nobody wants! It turns out my aluminum water heater had sprung a leak at the pressure relief valve. After an exhausting search for someone who welds aluminum, I was referred to Wally at Stewarts Radiator. I gave him a call and he immediately took my tank into the shop and repaired it on the spot! He was quick and efficient, and he didn't charge me a fortune!

I'm thankful for his help and plan to rest easy tonight...and not think about floods.

Wally is the bomb. He totally helped me out with my Scout customized radiator. He went well beyond to help me find and fabricate the radiator to fit. Thank you Wally.

Great and honest place to do business with. I did business with wally and his standards are high. The job was notup to his standards and he didn't want to charge me. I insisted on paying at least half my bill. Great work on my intercoolers

Call up looking for top tank on radiator. He explained he could do it for me at a fairly cheep price. Then he suggested call another auto parts store because by the time he changed the tank you would probably need a new radiator in 6 month any way. He said save your self the head ache by new. There are honest people out there.
