If there is no coolant present there is a possibility that you have a leak somewhere in the system and it will need to be pressure checked. The wire is the temp sender that goes to the temp guage on your dash. Once you are confident that the air is out of the system and the coolant level stabilizes, check for leaks, and test drive the vehicle at varying speeds for several miles. Out on the highway, it doesn't need the fans to cool the engine off, the movement of the car forces enough air through the radiator to keep the engine cool. Your engine produces more heat as it works under a load.
There are actu … ally two hoses that connect to the thermostat housing-one to the radiator and one to the water pump. Gently work the housing in the same way it came out, being careful not to rub off the sealant. Maybe you have a crack in your plastic radiator tank caused by your thermostat sticking and allowing your cooling system to overheat. In the front of the engine you can follow the top hose from the radiator and it will lead you directly to the thermostat. Then reverse the procedure, putting the new thermostat in.

There should be no pressure on the system if the vehicle is cold, but practice a safety-first approach and protect yourself properly.
The thermostat is on the passenger side of the engine, in a housing that is below the top radiator hose housing. There might air trapped in the cooling system. The thermostat will likely remain in the engine and can easily be removed separate from the housing. This is where things slow down a bit and patience is required. Posted on Dec 15, 2010 Check and make sure your fans are working.
Do not listen to guy who said follow the top radiator hose. Scrape the old Gasket off, if any. Facebook - Twitter - Instagram -. The vehicle should slowly reach operating temperature and the heater should become warm. This is the last step in the repair, but if you don't do this right the whole repair is at risk. Turn the knob on manual models from hot to cool to hot and listen for air sound change.
Then make sure that the cooling fans are coming on. Look for a housing at that location, which is usually held on with 2 bolts. If not, the refrigerant may not be charged up. Once the fan cycles, ensure that the coolant reservoir is full and turn the vehicle off. Code didn't say if it was the thermostat or thermostat sensor. Once you think all of the air is out of the system it probably isn't , put the cap on I suggest a new cap , let the vehicle run until the cooling fan cycles on and off one time.
It is approximately 2 inches to the left, and an inch or two above the fan pulley. The lower hose goes into the engine but it doesn't look like there is anything I can take off. Be sure to look at the direction of the thermostat as you remove it so you install the new one the same way. I believe there is an answer on this site for the thermostat and the sensor is ad … jacent to it. Stay tuned, I'll show you how to fix it. There is a large hose going into it.
I elevate the vehicle's front with jack-stands, a lift, or by parking on a sharp slope. I have removed the upper heater pump which has a 12 volt motor and Magnetic drive pump and the motor runs fine and pump end works great. Fit the housing over the thermostat and install each of the four bolts, starting by hand and tighten to the tension they were prior to removal. It is connected to the lower radiator hose so if you follow it up to the front of the motor there is the thermostat housing. Sounds like the second one to me. The air will slowly purge out of the system.
After motor has cooled down fill radiator with water till full, look make sure serpentine belt not broke, start engine run about 5 minutes, turn off, let sit 3 minutes, start engine look at temperture gauge is it over half way of gauge, Do you have a fan blade driven by water pump or electric fans? Once the coolant finished draining, I tightened the drain cock to 87 inch pounds. As soon as your engine heats up, the thermpostate opens and allows the coolant to circulate through the block and then back to the radiator. Let the vehicle get completely cold it may take hours depending on ambient temperature. Air will have to be purged from the coolant system. It was an independent shop.
