I wouldn't count on it for that!

if your temp gauge isn't rising, try a new thermostat.  The heater can
be pretty good on these even with a bad 'stat.

the temp sender unit is part of the multi function sender, the one on
the top rad. hose flange with four pins.  two other pins are for AC
related unctions, the fourth isn't really used.
