TracTuff K20/ K24 Water Pump Housing Delete

$139.50

UPDATE: Product shipping 1/2/23 and on will have three NEW changes that are now reflected in the images below. The alternator bracket is considerably bigger/ stronger and the pivot point has been moved up 3/8" to play nice with the Dailey Engineering Dry Sump kit. The plates tensioner window has been moved towards the -16 ORB port to eliminate tensioner misalignment and the plates treaded tensioner holder has been ditched for a precision ground stainless steel pin that is a prefect fit with the rod-end. The stainless steel pin is retained by a 5/16" circlip so you will now need retaining ring pliers with a .031" or smaller tip.

Several benefits can be traced back to the uncoupling of the OEM K20A, K20Z, K24A, and K24Z mechanical water pump from the crankshaft, such as a reduction in parasitic drag, which can free up horsepower and torque. Reduction or elimination of pump cavitation and associated troubles relating to aeration. Better control of the cooling systems temperatures through the use of electronics. Manually override pump and fan(s) to cool the motor while the engine is off. And lastly, the space you can free up by eliminating the OEM items.


Various alternators can be used with this kit but I highly recommend the S2000 unit. Late model B and D series alternators with a ribbed drive pulley fit the bracket but have fewer belt ribs than the crank pulley. The 2000-2001 DC2 Type R (B18C5) has the second highest amperage output. The 1999-2000 Civic Si (B16) has the lowest amperage output. If you are looking for the highest amperage OEM option and you are willing/ able to modify the lower mounting ear of the alternator...  you will need to buy my reducer bushing for the upper ear. The S2000 alternator conveniently has the same number of pulley ribs, natively rotates the same direction and has the same plug as the K harness.

Due to the various K series crank pulley diameters (OEM & Aftermarket) as well as multiple alternator pulley diameters... I do not provide belts. The tensioner in this kit does allow for a wide range of adjustment and in many cases the belts listed below, work. To determine the belt length on your own, simply wrap a string around the pulley's of the installed kit (with the alternator adjustment completely contracted), mark where the strings touch, measure that length and call an auto parts store with the length and number of grooves. If the number of groves are not available at that length, you can either go up to the next available length OR reduce the number if ribs.

NOTE: The K20A, K20Z, K24A, and K24Z water pump housing delete is NOT designed for use with A/C. I recommend this product for serious street cars and race cars, where it has been deleted.

The water pump housing delete hardware kit includes an o-ring, zinc plated hardware, a tensioner with 5/16" Rod-ends, a stainless tensioner pin, and a 5/16" circlip. The large 1-5/16"-12 SAE (-16AN ORB) port is the water inlet and the smaller 3/4"-16 SAE (-8AN ORB) port is a crankcase breather port.

The alternators pivot hardware is grade 12.9 so the bolt gets torqued to 59 lb. ft. (dry) and then the nyloc nut gets torqued to 62 lb. ft. (dry). 

You will need to apply Hondabond (not included) to the block, just like you would with the factory water pump housing, to seal the crankcase breather chamber.

If the tensioner is at the end of its adjustment range (75% of the threads shown) you likely choose a belt that is too long. This can and will lead to failure. Please find a shorter belt or order the XL Tensioner Turnbuckle.

All the associated support parts are offered individually and can be found by clicking these links. The plate inlet fitting, -8 breather port fitting, 20 GPM WP136S electric water pump mount for the Meziere WP136S electric water pump as well as a pump hose kit OR a 55 GPM WP336S electric water pump mount for the Meziere WP336S electric water pump as well as a pump hose kit to get water from the pump to the water pump delete plate.
