the water pump and thermostat should have solved it. an air pocket can cause that but usually not to that degree.

don't get one of those cheap *** plastic impeller water pump for sissies. Get the metal impeller one. get a cool running thermostat and drill two 3/16" holes in it 180 degreess from each other. you may have installed the t-stat backwards.

It sounds like you have an air pocket in your system. By the RH strut tower take the heater hose loose from the metal line and fill the cooling system when coolant starts coming out reconnect the hose. If that doesn't work jack the car up where the over flow tank is the highest point and fill the cooling system.

With the lower hose of the radiator disconnected, coolant/water flows out freely, right? If so, it sounds like everything is fine as long as it is not overheating. The lower hose will be cold for much longer than the upper radiator hose because as the thermostat opens and closes, the coolant/water circulates through the system. If no coolant/water is flowing through the overflow hose, you may need to add more coolant/water to the system once it cools down. Also, add some water into the overflow tank, or up to the Cold line on the tank. If coolant/water doesn't flow to the overflow tank still, you may need to replace your radiator cap.

1996 nissan altima no cabin heat, new radiator, flushed and filled, top hose hot, lower hose cold, newer thermostat checked good

HI Anon.
Remove your radiator cap (WHEN ENGINE IS COLD), run the motor and let it warm up a minute or two, have someone rev the engine a little while looking into the radiator. If the water goes down and/or you see the water moving, your water pump is good. If not this means that your water pump is bad and is not moving enough water through the system. Try Removing your thermostat and run the engine without it. Keep checking the radiator hoses to see if they are the same temperature. If they are not the same temperature the water pump is bad. If they are the same temperature your thermostat is more than likely the culprit. Hope this helps.

Hello. Here a non-photo diagram. Hope this helps!!!

The thermostat is located on the side of the water pump, the water pump is located just above the a/c compressor, the thermostat is fed coolant from the radiators lower radiator hose.
Thermostat :
1. drain coolant and tighten drain plug ( easier method : remove radiator cap, get big drain pan, place drain pan under lower radiator hose to radiator connection, remove clamp, slowly remove hose, allow coolant to drain into pan, now is a good time to remove radiator hose and clamp from thermostat housing )
2. remove thermostat cover / cap ( easiest to get at this when front of car is supported by jack stands and right hand side lower cover is removed ).
3. thermostat cap is held on by 3 bolts / remove thermostat.

You will notice that the thermostat's air bleed hole is pointing up and lines up with notch in water pump housing,,

ATTENTION :failure to install new thermostat in the correct location will cause engine to overheat.

1. install new thermostat to water pump, make sure air bleed hole lines up with notch, install and tighten bolts, install a new lower radiator hose, fill cooling system.

thermostat # 17670-77E00
lower radiator hose #17854-65G20
hose clamp #09401-36403
upper radiator hose # 17852-65G20

I have a 91 Nissan pickup d21 2.4 liter engine 2 wheel drive I have replace water pump thermostat radiator radiator hoses have bled the lines and it still runs hot water boiling in overflow.while truck is...

If you have a viscous fan hub then have it replaced as it is not moving the air through the radiator. Check how you placed the thermostat in the system as the bulb bit faces into the head or block so that it can sense the rising water temperature and open as required.. With not water moving through the hose I suspect that may be your problem

Car started knocking really bad got a cylinder 2 misfire code after opening coolant bleed valve with enging hot

Okay, it may be due to overheating, that may be the noise you heard, lets hope. first allow engine to cool, open radiator cap or the resivoir cap, which ever is the fill, remove the bleeder at top hose and fill radiator slowly until coolant comes out bleeder.

note if water pump was replaced due to leaking and engine was overheated at that time then it may be a good idea to replace the thermostat .
after filling is done start engine and allow it to run. watch temperature if temp start to climb past half way shut engine down and let sit for 5min. then restart and check level, in res do not open cap . feel air from fan and see if it is getting hot, this may take up to a half hour but do not drive,

A few questions, does this jeep have an electric fan?
when you heard the knocking was engine temp hot?
If you start jeep cold does engine knock?
Did this jeep get a new thermostat with waterpump job?
did it overheat when pump went bad and why did water pump get replaced?

sorry for all the questions ,just trying to get all the info to help you .

Have a 91 nissan pick-up staight 4 have it over heated oce replace thermostat and hose upper ran it for a day got hot again took out the thermostat and still gets hot what is the deal please help lee....

Replace the water pump, and also check for air in the system. Make sure the vehicle is cool, remove the radiator cap, start the vehicle and start pumping the lower radiator hose with your hand to help remove any air pockets in the cooling system. I would try this first before looking at the water pump or the fan since you let air into the system the minute that you removed the hose to install the thermostat and upper radiator hose

How to replace the thermostat?

If it's the 4 cylinder engine, the thermostat is in a housing where the lower radiator hose connects to the engine. I found that if you remove the power steering pump and set it to the side (don't disconnect the hoses), you can get to the thermostat housing more easily.
