any one has how to photos on replacing the thermostat on 1993sc300 "thanks"

 

no photos but its extremely simple you could do it in under a minute look at your lower radiator hose then follow it back to the water neck and you will find what you seek

 

This might help.

pump.
(b) Remove the thermostat.
(c) Remove the gasket from the thermostat.

INSTALLATION

THANK YOU for posting this thread! It was very helpful, I simply couldn't find the stupid thermostat and y'all's directions really helped!

For anyone else needing help:
I did NOT remove my engine undercover; I worked from above the engine rather than under. I just took off my intake tube (from the intake manifold to the airbox) to give me enough room to work. After that, it was easy-peasy to get at the two nuts holding the inlet on. I unscrewed them, the inlet popped off, thermostat popped out, and about 1/2 gallon or so of coolant rushed out (I also put an oil drain pan at the back of the undercover to catch the coolany - it got almost all of it). *I didn't even take off the radiator hose.

Thanks again, especially to "chanh55" for the correct torque amount.
