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 don’t last long on street cars is because they are often mounted metal-to-metal.

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).
