There are numerous types of form-in-place gasket materials that are used in the engine area. Mopar® Engine
RTV GEN II, Mopar® ATF-RTV, and Mopar® Gasket Maker gasket materials, each have different properties
and can not be used in place of the other.
MOPAR® ENGINE RTV GEN II
is used to seal components exposed to engine oil. This material is a
specially designed black silicone rubber RTV that retains adhesion and sealing properties when exposed to
engine oil. Moisture in the air causes the material to cure. This material is available in three ounce tubes and has
a shelf life of one year. After one year this material will not properly cure. Always inspect the package for the
expiration date before use.
MOPAR® ATF RTV
is a specifically designed black silicone rubber RTV that retains adhesion and sealing
properties to seal components exposed to automatic transmission fluid, engine coolants, and moisture. This
material is available in three ounce tubes and has a shelf life of one year. After one year this material will not
properly cure. Always inspect the package for the expiration date before use.
MOPAR® GASKET MAKER
is an anaerobic type gasket material. The material cures in the absence of air
when squeezed between two metallic surfaces. It will not cure if left in the uncovered tube. The anaerobic
material is for use between two machined surfaces. Do not use on flexible metal flanges.
MOPAR® BED PLATE SEALANT
is a unique (green-in-color) anaerobic type gasket material that is
specially made to seal the area between the bed plate and cylinder block without disturbing the bearing
clearance or alignment of these components. The material cures slowly in the absence of air when torqued
between two metallic surfaces, and will rapidly cure when heat is applied.
MOPAR® GASKET SEALANT
is a slow drying, permanently soft sealer. This material is recommended for
sealing threaded fittings and gaskets against leakage of oil and coolant. Can be used on threaded and machined
parts under all temperatures. This material is used on engines with multi-layer steel (MLS) cylinder head
gaskets. This material also will prevent corrosion. Mopar® Gasket Sealant is available in a 13 oz. aerosol can or
4oz./16 oz. can w/applicator.
SEALER APPLICATION
Mopar® Gasket Maker material should be applied sparingly 1 mm (0.040 in.) diameter or less of sealant to one
gasket surface. Be certain the material surrounds each mounting hole. Excess material can easily be wiped off.
Components should be torqued in place within 15 minutes. The use of a locating dowel is recommended during
assembly to prevent smearing material off the location.
Mopar® Engine RTV GEN II or ATF RTV gasket material should be applied in a continuous bead
approximately 3 mm (0.120 in.) in diameter. All mounting holes must be circled. For corner sealing, a 3.17 or
6.35 mm (1/8 or 1/4 in.) drop is placed in the center of the gasket contact area. Uncured sealant may be removed
with a shop towel. Components should be torqued in place while the sealant is still wet to the touch (within 10
minutes). The usage of a locating dowel is recommended during assembly to prevent smearing material off the
location.
Mopar® Gasket Sealant in an aerosol can should be applied using a thin, even coat sprayed completely over
both surfaces to be joined, and both sides of a gasket. Then proceed with assembly. Material in a can
w/applicator can be brushed on evenly over the sealing surfaces. Material in an aerosol can should be used on
engines with multi-layer steel gaskets.
