Default When do you replace thermostat on 2002 camry le v6?


I notice that the thermostat seems to work fine but in very cold weather
(-10 to -30) it temp gauge does not get to the middle point (normal area)
until driving for about 10 min.

Is this just because it is cold outside or is it because the thermostat
needs replacing? Also, on the cold days, it takes awhile before you get
warm air coming. Once the gauge shows normal reading, the air is fairly
hot. I have about 94,000 km or 56,000 miles on the car

Replacing it will help, 10 minutes it should be at temp. But a warning
3 out of four of non toy thermostats ive used in the years have been
defective in one way or another, The last one the thermostat was OK but
the gasket was to small always alowing cold water to bypass, Pay the
extra $ get a toy thermostat My new one cut heating in half just on the
gasket issue.

Its only like $15 for OEM thermostat and seal - replace it and see. Even
with newer long life antifreese it is still a good idea to change every 2
years - if you haven't done that do at same time. Not doing can cause heater
core and radiator failure.

I only use OEM Toyota parts on my car. The reasons why the cars are
reliable is based on part quality. If I short change on cheaper parts, the
reliability of the vehicle will suffer.

Thanks for the help.

I change the Toyota Long Life Coolant every 32,000 KM or 20,000 miles as
listed in the Toyota Canada Maintenance guide. I have changed it so far 3x
and the transmission fluid 2x as well in 94,000 KM or about 55,000 Miles of
driving. I think I am pretty good with maintenance and change the oil every
7,000 km using Mobil 1 5W30 and OEM Toyota filter.

Thanks for your help.

With a good thermostat the radiator is fully bypased till 180f. I get
a bit of heat starting in 4 minutes at zero

Well I don't have a problem with the heating as it does warm up pretty good,
I just notice that the temp gauge sits in the cold area for some time before
it starts rising. I will admit it has been -8 C to -20 C in the last few
weeks here so this may be normal.

I just plan on taking the car in for the 96,000 km (60,000 mile) service and
want to do the following things:

Perform 96K service
oil change using supplied mobil 1 5W30 full synthetic oil
replace coolant
clean PCV valve
check brakes
check Termostat

Any suggestions?

The only idea to partialy check thermostat is to see if radiator or
hose are getting warm before they should. A 180 thermostat will Start
to open at 180 not 175 and fully open at 200 or so. Meaning you should
be nearly in the middle, norm range before you get any heat passed to
the radiator. Changing with a Toy unit is cheap insurance. In maybe 6
minutes im hot at -10f now. Before it took 12-15 minutes, allbecause of
a bad gasket bypassing water.

Just like your fuel gauge sits on FULL for a gallon or two before moving
downward.

No. A typical 82C thermostat starts lifting off seat at 81.5C and is
fully open by 85C. The 81.5 will permit flow to the radiator.

In any case, the thermostat's operating rang has NOTHING to do with how
quickly the engine temperature climbs to (say) 70C (158F). Yes, I see
your mention of a faulty thermostat packing ring.
