They are noisy.  But make sure you have the air intake snorkel all put
together.  It helps a lot.

Mine runs just to the left of the LED, usually with the needle just
touching the edge of it.  But there are a lot of variations in these
temperature senders.  (Also, I'm told for some years the temp senders
for the glow plugs and for the temp gauge are different.  Make sure you
don't have them swapped.)

The only way to be sure is to either install a calibrated aftermarket
temp gauge, or buy an infrared temperature gun.
