This kit is designed to be used with our water pump adapters and a 2008 Gen IV LS3 Corvette water pump. Water pump adapters are HERE. Water pump adapter install is HERE.

All threaded holes in the block and cylinder head should cleaned and tapped with a thread chaser. All bolts being installed should be lubed with a light oil or anti-seize on the bolt threads before assembly.

The brackets are designed to used with Dirty Dingo water pump adpaters with a Gen IV corvette water pump and tensioner. Start with mounting the rear bracket to the driver's side cylinder head. Place the rear bracket directly against the cylinder head using the counter sunk 10MM, and 2 socket head 8MM bolts all 25MM long using stainless washers with the socket head bolts.

Mount the bottom brace in this orientation onto the block using 2 8MM X 25MM bolts and stainless washers.

If you are installing on a LT Gen V V6 engine- there is one hole missing for the bottom brace on the block. Install with one bolt and leave slightly loose. After installing the top bracket and bottom bolt, tighten this bolt into the block.

Install the front bracket and pump onto the engine.

"A" spacers fit behind the alternator and the rear bracket.

"D" spacer fits between the front and rear brackets.

"E" spacer fit on the top inside between the front bracket and the cylinder head.

The idler pulley mounts on the front of the bracket using the supplied pulley stand and bolt.

This will require using a factory tensioner from a 2008 Corvette and bolts to the front of the water pump on the passenger side.

Small case alternators are 135 amp and lower. Large Case alternators are 140 amp and higher.

Large case is on the left-
