Its probably your radiator not the schroud, when does it heat up? idle driving etc.
Idle ... I'm going to get the radiator checked but still want/need the shroud. I have an a/c that actually blows cold air!!
I have a bunch of stuff, including the plastic shroud. From a 1972 Scamp, /6 auto.

That shroud will not bolt up to your radiator, if It is the original radiator for the car. The early A cars had a clip mounted shroud which clipped and bolted To the side of the radiator, the later style bolts directly to the face of the radiator. Hope this helps, geof
