These 6061 aluminum 90-degree press-fit fittings are designed for LS1, LS2, and LS3 water pumps after removal of the original 5/8" and 3/4" heater hose push-in fittings.

Sold as a pair: one 5/8" fitting and one 3/4" fitting.

Important Installation Notice

These fittings are intended for experienced builders, fabricators, and installers only.

Installation requires:

  • Removal of the factory heater hose tubes
  • Proper reaming of the water pump housing
  • Careful installation of the press-fit fittings
  • Application of an appropriate high-temperature sealant
  • Pressure or flow testing after installation to confirm a leak-free fit

Improper installation may result in leaks, poor fitment, or permanent damage to the water pump.

Warranty & Return Policy

Fittings sold separately are not returnable once installation has been attempted.

Because installation is performed by the customer, Throwback Automotive cannot warranty customer-installed fittings or customer-modified water pumps.

Great product!
Size: 12 fl. oz. (Pack of 1)
Would recommend pouring oil into container after pouring in and shaking it up, great additive recommended by some old folks but I would have to say it’s just thick as molasses. Used in 2016 FORD F150 5.0 V8

Great for High Mileage vehicles
Size: 12 fl. oz. (Pack of 1)
Added into my 2014 Dodge Grand Caravan with 100k miles before a family trip and eliminated knock, slow starts and improved our gas mileage by about 10% I think! super easy to add to the oil and very happy with results.

Great assortment of clips—fits well and saves a trip to the dealer
Color: 40pcs
Picked up this 40-piece set to replace missing/broken push-type retainers on my bumper/fender liner area. The assortment is a solid value—having extras on hand is way cheaper than buying a few at a time locally. The clips I used snapped in securely and held the panel tight without rattles. Tip: match the old clip’s size before installing (hole diameter + stem length). I tested a couple first to confirm fit and then finished the job. For basic trim/under-cover repairs, this is an easy, cost-effective kit to keep in the garage.
