[745 TurboGreasel]

I got mine form Raceware, and they appeared very nice.
PN RWE-1010.
I followed these instructions to a T, the head has held for years.
The nut end threads are much finer than the block end ones, so 50Ft/Lb gives loads of clamping force.

Hi ,

The RWE-1010 instructions are below for reference. Normally we recommend (Teflon) pipe dope on the bottom of the studs, not Teflon tape, but I guess you could use tape too. The intended purpose is to keep the stud from turning when you install/remove the nut but to also allow removal of the stud by hand.

Regards,

INSTALLATION INSTRUCTIONS RWE-1010 CYLINDER HEAD STUD KIT

PLEASE READ INSTRUCTIONS COMPLETELY BEFORE BEGINNING INSTALLATION.

Correct installation is important for proper results. After cleaning the cylinder block deck per the VOLVO factory service manual, clean all head bolt holes with an 12 X 1.75mm tap and compressed air if possible. (Be careful not to allow debris to enter any other area of engine.) Peel the protective rubber coating off the stud threads by hand. Clean the threads with a toothbrush if necessary.

We recommend using a very light coat of Teflon based pipe sealant on the coarse threads of the stud before installation into the block. (The sealant is used merely to hold the stud in place if you remove the nut and washer at a later date.) We DO NOT RECOMMEND USING LOCTITE ON ANY OF THE THREADS!!!)

The studs should be threaded in by HAND ONLY until they bottom. NOTE: If you are installing the head on an engine in the vehicle, check for adequate clearance to install the head with the studs installed in the block. (Studs can be installed with head in position if necessary.) Make sure to install the head gasket correctly, etc. before positioning the cylinder head.

IMPORTANT
: When installing these studs in the block, make sure that the studs extend out of the block far enough to allow full engagement of the 12 point nut when installed with the hardened washer in place. In some instances this may require backing the stud out a few threads from being bottomed in the block. Do not back the stud out any more than necessary for full thread engagement in the nut.

After the studs have been installed correctly, use regular engine oil ONLY, (NO SLIPPERY lubes) to lubricate the stud, nut and washer before assembly. It is preferred that the washer be installed with the inside bevel facing up toward the nut. The nuts use a 1/2" 12 point (American) style socket. Torque the nuts in three increments using the torque pattern in the VOLVO factory service manual.

step 1 (25) ft/lbs. step 2 (40) ft/lbs. FINAL TORQUE 50 ft/ lbs.

We recommend running the engine until it reaches normal operating temperature then shutting it off and allowing it to cool to room temperature, then re-torque the nuts to 50 ft/lbs. again.
