Default Cold engine

95 Camry 288K

Engine gets warm but nearly warm enough for winter driving. The thermostat
was replaced about a year ago. Suggestions?

Where is temp gauge is motor hot or cold? Whos thermostat, did the
dealer do it and use a toyota, an aftermarket I had never sealed, once
I paid a mechanic to do one and he didnt do it, replace it again with
a toy unit if it doesnt get to normal range in 5 minutes, also a
clogged heater core, more than 50-50 antifreeze or the heater control
valve affect temp and interior heat. May be several things.

All of my Camry's have always had needle on gauge slightly below the
midpoint. This one is perhaps at the 1/4 mark.

====
Two things about Toyota thermostats - not sure if could be responsible
for your problem:
1) there is a "jiggle valve" - a small piece of metal in a hole in the
flange that should be positioned in line with a mark cast into the
thermostat housing - close to 12:00 o'clock.
2) the thermostats can be installed reversed, wrong side facing out
The jiggle valve helps remove trapped air from the cooling system.
Also could be, the wrong thermostat - wrong heat range. IIRC correctly
they're 180 deg. F.

The 1/4 indicator would be very low like its not closing. A cold motor
is not good as oil takes a long time to warm and cook out moisture,
the computer may make the motor run more rich longer, and milage
suffers. One I had put in once was to small to seal the housing, it
was aftermarket junk, A new toy unit fixed it. Get a good thermostat,
be sure you are 50-50 mix and the heater valve that directs heat to
the heater core works.

If your other Camrys did not have this problem, then it's either the
thermostat or the temperature gauge, and less likely overcooling.
Maybe check out the temp sender? maybe measure the engine temperature
at the coolant outlet, should be at or above thermostat temp at
operating range.

Once I went 1 winter with no heat, my mechanic said he put in a new
thermostat in the fall, and i trusted him as he trusted his employee.
A year later I replaced it again and finaly got heat, on another car
for maybe 2-3 years I got poor heat on a aftermarket unit that allowed
water to bypass the unit since it didnt seal right. Now I will never
use anything but a manufacturers unit. So twice in maybe 15 years for
me I had bad units or some no heat thermostat issue, it can easily
happen to someone else, few people check their cars like I do.
