i cant seem to find a How To or a pix anywhere of where it is located or how to install it.

any have a PDF of how to install it or at-least a pix of where it is located?

 

ok guy, so where the upper radiator hose is, connects to the inlet or outlet, but it is right inbetween the cam gear sensors, hopefully u follow so far, remove the upper radiator hose and i believe there is either 3 or 4 bolts, i'd like to think it's 10mm socket. In side you'll fing the thermostat.

 

The thermostat is connected to the upper radiator pipe near the head. If you take the upper pipe off you can actually see the thermostat in the housing if you look.

All you need to do is take the upper radiator pipe off and remove the housing, remove old thermostat, and pop the new one in, put the housing back on tighten the bolts, connect the upper rad pipe back and top off coolant

so after i remove my radiator hose? u mean.... remove what housing? is that that silver/gun medal looking thing holding on the hose to the block?

 

like everyone else said. follow your upper radiator hose from the radiator and it ends at the thermostat housing

 

The hose connects to a housing. The top of the housing can be removed. Its held in by 3 bolts. If you take the hose off, then take the 3 bolts out of the top of the housing (might be snug on there, just move it back and forth until it pops off) then you'll see the thermostat. The thermostat just sits in there. Simply pick it up and out of the housing (maybe you want to get a towel/rag and clean the housing) then put the new thermostat in. Then, replace the housing and hose

i got the it out.. only bad thing is the retard working at NAPA gave me the wrong part.

i said 2003 midsu lancer Evolution, dual over head cam. and he still give me the wrong part.

 

can i run no thermostat or will it leak?

 

It will leak. At least I think so - the rubber grommet on the thermostat is what seals the housing.

you can run with no Tstat...just gut the housing and bolt the housing back on.It will take you motor forever and a day to reach proper operating temp though

my locked up,so i gutted it as a temp fix

 

keep the thermostat in there. running a motor under proper operating temperature is bad for it

 

the motor will eventually reach operating temp,it just takes longer. A LOT longer

 

when you start moving the engine temperature will drop below operating temperature...

im not sure why you would even go without a thermostat. they arent even expensive and there is no benefit from it
