how to/? is this a question, formed as a statement?
same as all cars, youtube it yet? like 10000 posts like that.
see that large top rad hose, it goes to thermostat houseing
drain coolant,
remove housing with hose.
remove stat
put in new stat, not backwards and bleed hole up hill.
new seal
reverse above, and fill with fresh 50% AF.
id flush the system at drain but that's just me.

double posted with word HOw.
SEE LAST POST,

It is on the distributor shaft, along with the cam angle sensor

you need the right software and a multi use ob2 reader. pro scan 5.9 will read the system but you need the right ob2 tool for it to read. there is this site that may help you. http://www.micro-tronik.com/mercedes_benz_diagnostic_software_13.html

what engine, they offer many.
and if you google image search it, most times, its there.
or at alldata.com

It sounds like transmission overhaul time to me.

where is water pump located on 1994 camary engine

check your thermostat to see if it is stuck closed, check your water pump for circulation, check your fans to see if they are coming on.

Flush your regulator, and replace your fan cooling system.
