This is a quote from a popular auto repair book:"It is rare for the temperature gauge to fail,but if it is erratic in operation check the lead from the (temp. sensor) switch for broken insulation and earthing.If the gauge reads maximum,suspect the sender switch(temp. sensor)." The switch can only be tested with an ohm meter or by substitution of a new unit.I just replaced my tem. switch and it didn't fix my gauge!So...

how to replace a heater core on a 2003 Nissan Altima 2.5
Begin by removing the water supply lines from your Nissan heater core. Remove the heater core retaining bolts. The heater core will come out.
For example a 2000 Nissan Sentra and a 2000 Daewoo Laganza are the same heater core but the Maxima is not..............
where is block heater on my altima 2006
the heater core is behind the dash board
My Altima had that problem and it was the water pump going out. It started with temperature gauge was moving, but then it started leaking and finally the heater stopped being warm at idle.
The Nissan Sentra should not have any other heater installed due to fire hazards. The stock one is very good.
The heater fan ONLY blows the air, it does not make the temperature of that air. Your heater temperature controls how hot the air is. Adjust your heater temperature for hotter or cooler air.

Is your passenger floorboard wet? Same sort of thing happend in my stanza and it was the heater core. I just bypassed it, but if you do that you will still be stuck without heat. * * * My sister's car had the same symptoms and it turned out that her water pump was bad. Without circulating the water/coolant, there was no way to get water flowing though the engine to cool it down, and no water going through the heater core to warm the interior. -Also, the thermostat can cause this, especially if your coolant is old and dirty.
