Since u gave no specific car info, generally the thermostat is at the end of the top radiator hose where it attaches to the engine block. Remove top hose at engine. Remove the two bolts that hold hose connector to engine block. The thermostat is between connector and block. Lift out. Replace. Put everything back together. Fill radiator back up. Ur done.
Top radiator hose, one end goes to the radiator, the other end goes to the thermostat housing at the top front of the engine, three bolts to undo to remove the housing and access the thermostat. If you remove the radiator cap and suck out the coolant from the top of the core then none will be spilled when the thermostat housing is removed.
Open the hood and find the radiator. Get help and a flashlight if you need to. The radiator should have two black hoses attached to it, one on top and one on the bottom. Those hoses are about 2 inches in diameter, maybe a little larger. On cars made up to about 1985, the thermostat was found at the engine end of the top radiator hose. There would have been a bell-shaped housing with the thermostat inside. These were usually rear wheel drive vehicles. Cars made since the mid-80's and particularly front wheel drive vehicles have the the thermostat located at the engine end of the lower radiator hose.
There is an over-flow hose between the coolant recovery tank, and the top of the radiator just below the radiator cap, and there is also an over-flow hose from the top of the coolant recovery tank and it just hangs over the side of the recovery tank and runs the over-flow off out under the front of the passenger side fender well area.
Get some boxes, bags and a sharpie marker to put things in and label them if this is your first time. Disconnect and remove battery and metal battery tray, unplug ALL wires and lines that connect to engine including AC lines that are in the way and the throttle cable and cruise control cable. Keep the plug wires hooked to your distributor so you don't lose your firing order. Drain radiator and remove it. Remove the top hose and use the long lower hose to push over the outlet where the top hose was to contain what is left in the radiator. Automatic cars will require disconnection of the transmission cooler lines from the bottom of the radiator. Open gas cap before disconnecting fuel line on intake to relieve pressure. Remove front wheels and separate bottom ball joints from lower control arms on each side, separate both outer tie rod ends from knuckle. Drain transmission fluid, pop out both axles from transmission. They can hang. Disconnect shifting linkage. Disconnect exhaust down pipe (or) disconnect tailpipe at the end of braided hose just before the catalytic converter. Mainly, get it to where the motor is just sitting there in the cradle with nothing holding it but motor mounts. Hook a chain to the pick bracket on the head near the power steering pump and to the one on the transmission. Feel free to remove the 17mm bolts in each mount as well as any brackets for these mounts that obstruct your ability to pull it up out. I have found that pulling it out on an angle with the transmission being lower helps your mood! The 4 motor mount locations are as follows: Front Center - Left - Right - Rear Center. If you are replacing this 90-91 engine with a 92-93 you will need to reuse your AC compressor and it's bracket, the down pipe and the header and the wiring harness on the engine.
This hose you refer to is the breather tube for the differential. It connects to a fitting at the top of the differential housing and runs up the back side of the radiator so you won't run the risk of water entering the differential if you submerge the front axle in water. Reconnect the rubber hose to the fitting on the differentail.
1.Disconnect the radiator fan motor connector.2.Set the temperature control switch to the hot position.3.Loosen the radiator drain plug to drain coolant.4.Disconnect the upper and lower hose and overflow tube.5.For vehicles with automatic transmission, disconnect the oil cooler hoses from the automatic transmission.Plug the ends of the oil cooler hoses and the automatic transmission fittings to prevent transmission fluid from spilling out and foreign material from entering.6.Remove the radiator mounting bolts.7.Remove the radiator and the fan motor together.8.Remove the fan motor from the radiator.
