Napa/Gates/Dayco Radiator hoses #4625691

I'm in the process of replacing the radiator in my Corolla; top plastic tank got a pinhole leak that turned into a geyser. Went with a Denso replacement. Car has a tick over 200K; the factory radiator hoses still look good but since it will all be apart, I figure I'll do the hoses since I plan on driving the car into the ground.

The title says it all; those are my local choices for hoses. I've read Napa = Gates. What should I use??? I'm leaning towards the Napa since they are cheaper. My main concern is fitment and total diameter being equal to the factory hoses so I can reuse the factory spring clamps.

Thoughts? Thanks!

I'd probably go on Amazon and shop for some OEM hoses. Maybe even just leave them alone if they aren't soft or leaking. They can last the life of the car and are designed that way.

Throw those factory clamps in the trash! They are generally a 1 time use. Once removed they often let the hose leak. I work at a radiator shop and hate spring clamps with a passion! Get a quality screw clamp. Recheck it after a few weeks and your good to go.

I knew you'd say that Chris! I value your opinions, but in my experience, the factory spring clamps are the bomb. They never leak or need re-tightening. I always try and reuse them.

Do you have any input on the hoses?

Toyota hoses weren't particularly expensive for my Camry

Maybe $20 each

I like OEM on things that can jeopardize an engine (radiator cap)

Consider a variant of the worm clamp, the constant tension clamp

+1 screw clamps with the exception of constant tension belleville spring types are one of the worst things ever foisted on an industry.
When you start getting down below freezing they loose tension and leak requiring constant retightening and consequently damage the hose, its common to see the hose poking through the slits on screw clamps.

I prefer Gates or OE to Dayco aftermarket, one trick to reusing the spring clamps is to put them on the neck first then put the hose in the clamp as its going on. Getting the clamp over the hump is the most common problem when using aftermarket hoses.

Fixed it for ya. You experience with screw clamps does not reflect their performance in other parts of the country especially where the temps drop below freezing and worse. If you worked in up here in skunk hollow you would have a trash barrel full of them.

Yea Trav; we get seriously extreme temperature swings throughout the year. If you installed a regular worm gear clamp in July when it's 95 degrees, come January when it's 10 below, it will be very loose.

For reference, this is the type of constant tension clamp that you DO want


And this is the one you Don't want to reuse



If your willing to buy new at the dealer, they're great

Not so great as they age and get R&Red during repairs

Dayco,napa/gates are good hoses. Dayco is often smaller diameter. Back to spring clamps. We stopped reusing them due to all the combacks when we reused one.

Same here.... I once was a skeptic, but now I love factory hose clamps.

I prefer Dayco over Gates anyday. They usually are thicker. Don't waste your money for OEM hoses..

Hoses should be good whatever you get..... As long as they stay dry and no oil contact, they are so good.
