Engine vibe after new radiator?
Why would I get an idling engine buzz felt throughout the car after simply having a radiator swap? It seems to abate when I turn the wheel at idle without moving thereby changing the rpms down under load. Weird.

I can't see any mechanical reason to link a Radiator to a vibration, unless some of the mounting bolts were left loose.

A lot of cars use pin type mounts on the radiator, if I recall correctly this is the type found on the SVX (too lazy to go look right now.) If the pins aren't centered in the mounting rubbers you can pick up a vibration. Also check that the bottom of the radiator is sitting where it belongs, I've found a few that weren't properly installed. One more item to look at are the top and bottom rad hoses - make sure they aren't old and stiff and that they aren't pulling/pushing/twisting the radiator away from its intended position.

The hoses are new also, I think it's the rpms-somehow changed too high since it smoothes out when the PS pump is loaded by turning the wheel slightly and holding that position...
