Nissan: 88 nissan pickup not heating up

Did you replace all the parts with the correct ratings ? For example if you
put a lower rated thermostat could do that...... It does have fluid right ?
You might try a higher rated thermostat in it ...... It is better to run it
at designed operating temp.

ALSO are you SURE your gauge is working correctly ? Does it move at all ?
Could be a temp sensor or some other electrical problem as well...........

Happy New Years

Where did you buy the thermostat? Try a dealer one and your problem will go
away. The -only- thing that will make an engine run too cold is a
thermostat that is opening too soon.

Well I really really really would like to belive all what was written above
but my thermostat was replaced by me three times already (I do it with
coolent changes) it seems unlikely that all three would be bad and yes they
were after market thermo's witht the correct ratings I even put a hotter one
in. The guage works the sending unit works I know because in the summer the
truck heats up I know there is something unique that is causing this
problem. I would love to put in a new oem pump/fan but I really can't
justify the cost. This truck has 520,000 km on it. I am hoping someone has
seen this specific problem

I think you have a bad temperature sender or a electrical problem

Happy New Years

A swing and miss M all have been checked and my original post says that my
truck does not heat up not that the guage or anything else is not working.
Sending unit has already been replaced. The engine itself does not come up
to running temp. I am beginnning to think that the fan is spinning way to
fast

But thanks for your input

Well you do mention that your gauge doesnt go beyond C. A electrical
problem could cause this appearance of a symptom. If your engine is running
any distance at all it WILL produce a lot of heat. The detection of that
amount of heat is purely a electrical transaction.

I have but you won't believe it aftermarket thermostats are junk. Think for
a moment, how can anything else cause it to run too cool? The thermostat is
suposed to stay CLOSED until the engine warms up. if the coolant isn't
moving, how could the fan do anything?


Hey but instead of spending $15 for a good one, buy a $400 fan/pump and
clutch and see that it doesn't change anything! Sheeze!

You're way off track. If you remove the fan entirely and drive it down the
road it still won't warm up unless you're sitting totally still. The fan
only keeps it from overheating when sitting still, the fan/airflow doesn't
control the engine temp on a water cooled engine.
