2002 P.T. Cruiser Overheating Problems?

Yeah, same goes for the brake cylinder reservoir. After about a year of
southwestern under-hood temperatures, they're so opaque you can't see a
thing.

 

After just now re-reading the FSM, I think you are 100% correct.

Same on 2nd gen. LH. As Joe has pointed out in another post replying to
you, the 2nd gen. thermostat is down low on the side of the 2nd gen. LH
engines. This may surprise you, but the thermostat is on the inlet side
of the engine in the 2nd gen (at that engine end of the lower rad.
hose). So the housing that is traditionally where the thermostat is
just an empty housing (except that on the 2.7, it also has the bleeder
valve on it). This makes the replacement of the t-stat on those engines
(2.7L, and 3.2/3.5L) a bear to replace the thermostat on. Also, many
people don't realize that the thermostat isn't in the traditional
location. The FSM even mistakenly refers to that housing as the
thermostat housing in a few places (boilerplate copied over from other
FSM's and not caught). In case you're wondering what the proper name is
for it since the thermostat isn't in it? Engine coolant outlet housing.

I knew that was true on the 2.7, but wasn't sure about the 3.2/3.5/4.0
family.

I gather that its not actually a reverse-flow system like the GM Gen-III
engines, so I assume that the thermostat bypass flow somehow is routed
in such a way that it allows the thermostat to sense the outlet temp
while regulating the inlet flow. Seems strange- what's the claimed
advantage?

 

it called the reserve bottle cap lloks just like a raditor cap because it is

 

You are correct.
