RADIATOR MOUNTING BRACKETS
To save weight, the radiator mounting brackets are now made from aluminum. The previous design used steel.
For durability, it is important to completely rubber mount the radiator using
Chevrolet radiator pads, and making sure that nothing rubs on the radiator core.
The aluminum radiators need to be rubber mounted to protect from vibration
and from electrolytic corrosion. One of the reasons the all-aluminum racing
radiators dont last long on street cars is because they are often mounted
The Stealth Conversions brackets shown above, are used to mount the Chevrolet
style radiator to the Z car using rubber mounting pads (from a 1986-1993 S10
Truck) that isolate the radiator from vibration and electrolytic corrosion.
The brackets come with the rubber mounting pads (GM part #12338053).
The brackets have alignment holes which hold the rubber pads in place for installation
purposes, but silicone sealant must be used to hold the rubber mounting pads
to the radiator brackets.
For installation information, see page 12-10 of our Datsun Z Car V8 Conversion Manual (The Cooling System
chapter -- you can download
a pdf file of it, too).
