Here are some installation tips which can be useful in
any application.

GENERAL INFORMATION
Allow engine to cool before disassembly – This is
especially important with aluminum heads or engine
blocks. The risk of warpage is greatly increased if the
engine is disassembled while hot.

INSPECT OLD GASKETS (IF POSSIBLE)
If original gaskets were leaking, determine if there
was a problem with the mounting surface. Check
flanges and surface area for straightness, deep
scratches or imperfections. Repair or replace as
necessary.

CLEAN ALL MATING SURFACES
Remove all gasket material, oil, grease, rust etc. from
mounting surface using a wire brush, scraper or gas-
ket remover. When cleaning aluminum surfaces be
very careful not to damage, scratch or nick the surface
area.

ENGINE FASTENERS
On newer engines built today, torque-to-yield head
bolts have been used.

Most of these cannot be

reused and must be discarded; new bolts must be
used. Mr. Gasket has available premium fasteners for
most engine applications.

Refer to the engine service manual when in doubt if
bolts can be reused. When reusing bolts, thoroughly
clean bolt threads and shoulder of bolt under the
head, be sure to remove all foreign material. Carefully
check entire bolt for damage such as stretched
threads or evidence of galling. Where there is any
doubt, do not use it. Replace it with a new bolt.

INSURE CORRECT FIT
Always test-fit the gasket to insure you have the
correct gasket for your application.

HEAD GASKETS
Reverse torque sequence when removing head bolts.

Thoroughly clean all engine block threads and head
bolt threads.

FORM 97140220 (Rev A) 01/12

Using a straight edge and feeler gauge, check the
mating surfaces for flatness. Each surface must be
checked four different ways. Check the length, width,
corner-to-corner and opposite corner-to-corner. Deck
flatness should not exceed .003” for both cylinder
head and block combined. If the allowable tolerance
is exceeded, the mating surface must be machined
and brought back to proper specifications.

Never enlarge, restrict, or modify any head gasket
yourself. Overheating and premature engine failure
will result.

Do not use any type of sealer on composition type head
gaskets.
IMPORTANT! Use thread sealing enhanced pipe sealant on
head bolts entering water coolant passages. Lightly lubricate
all other bolt threads with moly lube or 10W30 motor oil.
