Looking for a bolt

Toora Stephen · May 27, 2012

Does anyone know the thread of the bolts that attach to the bottom of the radiator to hold it in place?

353 828 X1 Bolt (7/16" x 1-1/4" NF, Carr.)

There is no separate "bolt" to hold the Radiator in place, it is a threaded piece welded to the bottom of the Radiator support. The support is part of the radiator and you would need to have something welded to this support The thread was coarse UNC possibly 7/16" UNC from memory. This screw has broken off as it was seized with rust...John(UK)[email protected]

If your radiator is slotted at the bottom, the part number with size description will simply slide into position with the carriage bolt head holding it in place.
You should then be using;
353 426 X1 Washer (7/16" Lock)
353 526 X1 Nut (7/16 NF, Hex.)
This is also using the
180 705 M1 Pad, Radiator Mounting

The above mentioned pad is made out of rubber.

Typically NF does not loosen up under vibration as easily as NC thread. NF usually also will take a higher torque value.

(quoted from post at 04:50:27 05/28/12) There is no separate "bolt" to hold the Radiator in place, it is a threaded piece welded to the bottom of the Radiator support.

Of course you're right. What I am after is the nut that attaches to this bolt. Sorry everyone, my brain was muddled...
