Dorman OE Solutions Coolant Water Outlet for K Series

Dorman OE Solutions Aluminum Coolant Water Outlet - K-Series (19320-R40-A01)

Found a coolant puddle under your K-series, or spotted that crusty pink residue creeping around the thermostat housing? Yeah, you're not alone, and it's not your imagination. The factory water outlet on these cars is plastic, and after years of heat cycles it goes brittle and cracks right at the welds, and then it starts dumping coolant. This Dorman OE FIX outlet solves that for good. Instead of plastic, it's made from corrosion-resistant aluminum, so you're not just replacing the failed part, you're fixing the design that failed in the first place.

Why The Factory Plastic One Fails

Here's the story every K-series owner eventually learns. Honda built the water outlet out of welded plastic, and plastic doesn't love sitting in an engine bay getting cooked and cooled thousands of times. Over the years it gets brittle, and eventually those plastic welds crack. Sometimes it's a slow weep you catch as dried coolant crust, and sometimes it lets go all at once and you're watching your temp gauge climb on the side of the road. Either way, coolant loss on a hot motor is how you end up with a much bigger, much more expensive problem than a leaky housing.

Aluminum Means You're Not Doing This Again

This is the whole point of the upgrade. Dorman makes this outlet from corrosion-resistant aluminum, which handles underhood temperature swings way better than the welded plastic original and just doesn't get brittle and crack the way plastic does. So it's not a matter of when it fails again, you're done with this repair. That's what makes it worth doing right the first time. It's application-specific, built to match the fit and function of the original, so it bolts up like the factory piece with none of the factory piece's weakness. Dorman even backs it with 50-point quality and exaggerated lifecycle testing, which is exactly the kind of over-testing you want on a part whose whole job is to not fail.

What's Included, And What You'll Need

Read this so you've got everything before you start. The outlet comes with a new EPDM gasket, so your seal is covered. What's not in the box: the thermostat and the mounting bolts. So plan to reuse your bolts (they're usually fine) and either reuse your thermostat or grab a new one. Honestly, while you've got the housing off and the system drained, a fresh thermostat is cheap and it's the perfect time to do it, so you're not back in there later chasing a stuck-open thermostat and a car that won't warm up.

While You're In There

A couple of things worth doing since the system's already open. Take a look at your hoses and clamps while you're at it, since old ones get hard and brittle right along with that plastic housing. And do yourself a favor and bleed the cooling system properly once you're back together, because trapped air will have you chasing a temp gauge that swings for no reason.

Note: Dorman OE Solutions OE FIX coolant water outlet (thermostat housing) for K-series applications, a direct replacement for OE part number 19320-R40-A01. The original outlet is made from welded plastic that becomes brittle over time and can crack at the welds, causing coolant leaks; this replacement is manufactured from corrosion-resistant aluminum to better withstand underhood temperature extremes and resist leaks. It is application-specific and matches the fit and function of the original. Includes one EPDM gasket. The thermostat and mounting bolts are not included. One water outlet per order.
