Honda K24Z7 Water Pump Assembly 19200-RX0-A01

Honda K24Z7 Water Pump Assembly - 19200-RX0-A01

Your K24Z7's leaking coolant from the water pump or you're hearing a grinding noise from the front of the engine? Part number 19200-RX0-A01 is the OEM water pump assembly for K24Z7 engines found in the 2013-2015 ILX and 2012-2015 Civic Si. The water pump circulates coolant through your engine to stop it from overheating. When it fails, you're seeing coolant dripping from the weep hole, hearing bearing noise, or worst case your engine's running hot because the pump's not moving coolant anymore. Fresh water pump gets your coolant flowing again and keeps your engine temps where they should be.

Here's How They Fail

Water pumps die in a few ways. Most common is the seal going bad. You'll see coolant weeping from the weep hole at the bottom of the pump. That's the drain hole that lets you know the internal seal's blown. If there's coolant dripping from that hole, your pump's toast. The bearings can also go. You'll hear grinding or squealing from the timing chain area. Grab the water pump pulley and try to wiggle it. If it's got play, the bearings are shot and the pump needs replacing. Sometimes the impeller breaks or corrodes and stops moving coolant properly. Your engine runs hot but the pump's not leaking and it's not making noise. Any of these means you need a new water pump.

Don't Gamble on Cheap Aftermarket Pumps

You can find aftermarket water pumps for half what OEM costs. Some work fine. Some leak the day you install them, some die in six months. The OEM Honda pump's built to the same spec as what your engine came with. Good bearings, proper impeller, seals that last. It costs more but you know it works. If you're replacing a water pump, you're pulling the timing chain cover off and tearing into the front of your engine. That's hours of work. Don't save forty bucks on a sketchy pump and end up doing the whole job over again in a year when it fails. OEM pumps last. That's what you're paying for.

Do the Thermostat and Gasket at the Same Time

When you're in there doing the water pump, replace your thermostat too. Thermostats are cheap and they fail without warning. If your thermostat sticks closed six months after you've done all this work, you're overheating and you're right back in there tearing the front of the engine apart again. Do it now while everything's apart. Same with the water pump gasket. Don't reuse the old one. Get a fresh gasket and make sure it seals right. The gasket's a few bucks and it saves you from chasing coolant leaks after you've put everything back together.
