Default Replace themostat on 1999 Camry

Greetings,

A couple of weeks ago my check engine light came on. The car was
running fine but I brought it in anyway. $350 dollars later I had a
new O2 sensor and a light that was still on. I went back to the
Goodyear and now they told me I also need a thermostat. Something
about the car not reaching operating temp fast enough.

Well, after getting banged in the shorts for $350 already I thought I'd
try this repair myself. I used to work on cars many years ago before
all these emission controls and computer controls. I figured it would
be easy to find a guide online for replacing a thermostat but no such
luck.

I have found online that I need a thermostat and an o-ring. However, I
can't find anywhere that tells me exactly where the thermostat is on a
1999 Camry LE 6-cyl. If it is located where the top radiator hose
enters the engine block there is an assembly that is held on by about 6
bolts. I remember in the old days all you did was pull off a hose and
put in a new thermostat.

Anyway, point of this long post is to ask if anyone can give me a
walkthrough on replacing a thermostat on a 1999 Camry LE 6-cyl. Thanks.

You should go to Autozone and borrow for free their OBD-II reader. Read
the codes from the car's computer first before doing any more work.

Having never seen my 99's thermostat removed, I had assumed that there would
be the usual gasket between the housing and the block, not o-rings. I recall
occasional problems with the old gaskets in Chrysler products.

Japanese imports usually us a gasket that wraps around the thermostat
plate.

And the housing compresses the gasket for a seal. The traditional
o-ring for the thermostat housing (other outlet(s)) is just an o-ring
between the block or a pipe leading to the lower rad hose.
