Default 90 EX Thermostat location.

Looking to replace the upper and lower radiator hoses along with the thermostat. Where is the thermostat located? Any tips on replacing these items?

Follow your lower radiator hose. It will lead to your thermostat. Location should be below the Intake Manifold or around that area. You should also see the coolant temp sensor deal.

Yea, getting to the lower radiator hose is a PITA. My suggestion is to get under the car and look for the clamps, you might have to take off the fan on the passenger side to get at it. The upper is easy as pie. For this you might as well do a radiator flush since majority of your fluid will be coming out anyway .

Just when you're done bleed the cooling system (bleeder valve right by the t-stat) and make sure all your clamps are positioned to where you don't have to take the fan off to get to (lower hose) and that they are tight!

Removing your intake will give you a lot more room to work with also.

On the block where the lower radiator hose connects to the block. Actually the lower radiator hose connects to the t-stat then the t-stat connects to the block .

ONE MORE QUESTION FOLKS:

Cant seem to find the bleeder valve. Is it simlar to the brake bleeder valve on the calipers? I see something similar to this by the lower hose on the block. If this is it, i would need to bleed it with a wrench, just like the brakes right?

It will look like the same thing...it has that same nipple on there and it is just past the lower radiator hose and right by the t-stat. And it should be exactly like the brakes except you run the car while the bleeding apparatus is hooked up and it bleeds out the air and when you get coolant wrench down the bleeder valve.
