3208 with a single thermostat

[dspithaler@...]

Bill, I replaced mine a year ago & I didn't have any trouble with the one
with the nut I was able to reach around in the back to put a wrench on it. Mine
is a 300 TA. You would think that yours only had one thromostat it would be
the same as mine. I'm going to open the back of mine up in a day or so &
check some things. I thought mine was shown in the cat manual. I'll look
tomorrow.

Hi All,

Well, I worked on the hoses and cooling system today and visited the
local Cat dealer.

I am having severe concerns and hesitation, about changing the
Thermostat.
The Cat shop had several exploded drawings and all were different
than my 88FC.
They were surprised to find a drawing of a single thermostat , They
said " most all 3208's have two thermostats." I also talked to an
old time 3208 Cat mechanic, He thinks there is a nut in the rear,
behind the back plate, he said "the cylinder head may need
to be removed". Yikes!

There are three bolts on the housing, the top right has a rear nut,
the lower right has a bolt that threads into the back plate. The
bolt on the left side of the housing seems to have a nut in the
rear, It is impossible to reach with your fingers, wrench or needle
nose pliers.

The single thermostat housing appears to bolt to a plate that mounts
to the dual thermostat fixture. The thermostat housing has a Cat part
number, but it is different than the part number on the Cat exploded
drawings.
I have talked to Jack Bentley who has changed his 300 Hp 87FC
thermostat and his description is also different.

Has anyone changed a single thermostat on a 300HP Forward Control ,
3208 turbo, with the air to air cooler.

I now believe that all of these Birds are different.

Any advice is appreciated,

Bill 88 FC, with a clean flushed radiator and some new hoses.

There are two thermostats, and two nuts behind the accessory plate that need to
be secured to remove the thermostat housing. There are two gaskets that need to
be renewed at the time the housing is R&Rd. Do not use silicone sealer on these
components. Make sure the coolant PH is correct. The kits for checking are
available from Napa or any truck supply house. Make sure the engine is well
grounded, electrically speaking. That's important.

Many thanks to Mike for his great 3208 knowledge.

The engine in the 300hp, FC seems to set back about 4 inches to
accomodate the air to air cooler. This makes the space on the right
side really tight. I crowled into the doghouse and there were the
bolt/nuts behind the accessory plate. They were easy pickens with a
needle nose vise grip pliers. Mike said "two man job", so Patty
helped with that extra pair of hands.
There were two holes for the thermostats, But there was also a plate
another gasket and the SINGLE thermostat housing.

Thanks again to Mike he really knows these 3208's
