Question about Toyota Land Cruiser

1 Answer

97 Landcruiser. It overheats, and the water does not seem to be circulating. (No pressure or water flow through upper and lower hoses). Is this a water pump? I always thought water pumps leaked and made noise when they failed. I also wondered if I may need to bleed the system, although it was never leaking water?

Before throwing a waterpump at it, try a thermostat. If that sticks shut you'll get no circulation and overheating. A way to test, pull thermostat and TEMPORARILY run it without thermostat.I stress temporarily and just for test. You should see water circulating through radiator then. If not then you know waterpump is bad.

2002 dodge caravan 4 cylinder. Recently replaced the radiator hoses and water pump, now vehicle is pushing fluid out the resivoir overflow spout. Causing the engine to overheat. What could cause this?


The problem is the coolant isn't circulation through the system. You are getting all the pressure on one side of system and the tank is the only place where the pressure can be released. Is the thermostat good? Is it installed correctly? Check for coolant in the radiator. After vehicle has been running but turned off feel the upper radiator hose is it under pressure and hot. Next feel the bottom hose is it under pressure and cooler than the upper hose. If the upper hose is not under pressure fix thermostat it's not working correctly. If lower hose is not under pressure something is wrong with the radiator

How to tell if the water is circulating in motor

The water in my mazda bongo wont circulate top hose gets very hot while bottom hose stays cold , heater wasnt working but now managed to get heater working after bleeding the system but bottom hose still...


Check the radiator-it may have blockage. Take it off and turn upside down and flush from the bottom.
If the top hose gets hot, that means the thermostat is opening. The bottom hose should be at least warm, and quite warm if radiator flow is good.

I have a 1992 Buick regal that overheats at speeds of 40 mile n hour it has a new radiator, thermos stat, has been flushed an filled and bled have not changed the water pump when it overheats all of m


It is more than likely your water pump. Can you run it in park with the radiator cap off. The cap on the radiator not the overflow tank. When the temp opens the thermostat you should see flow if the pump is good no flow it is probably bad. If you don't see flow check the upper hose for temp and the lower hose. If the upper line is barely warm and the lower hose is significantly hotter, it is either water pump or thermostat, but since you replaced the thermostat I would be back to water pump. BTW you should use either a contact thermometer or an infrared to check hoses, although it was done by hand in the old days.

1988 b2200 is overheating--we've changed out the lower radiator hose, thermostat, and the upper hose is fine. Why is it overheating? Radiator, heat pump, or water pump?


!st check and make sure the water is flowing in the radiator, then check
the timeing, Mazda will run hot if the timeing is rong.

1999 grand prix gt overheating. Changed thermostat, water pump, upper radiator hose. Please help!


does the upper and lower hoses seem to be the same temp when car begins to overheat? ore the radiator cooling fans coming on before the car overheats? did you pressure test the cooling system and radiator cap? also may want to remove the lower hose and flush the radiator. is the check engine light on and does it run bad?

2005 Chevy Impala...all I did was change the lower radiator hose because it was leaking. Now the car overheats, the upper hose is hot and the lower hose is warm. Does this model have vapor lock issues or...


the lower radiator hose is a return hose and there are no vapor lock issues. If your coolant level is full when you start your vehicle and when it heats up and the system pressurizes your coolant expands with heat and then that excess pressure will go through the overflow outlet to the reservoir and the reservoir has a relief opening near the top to relieve pressure or for excess fluid to come out. If the lower hose is just warm then your water pump may not be circulating properly (be sure to check belt for tension no more than 1/2 inch of play should be present). One messy way to test water pump would be to first drain coolant if it is good to reuse it, then remove the lower hose, open the radiator cap and put a water hose in it and turn on half way. Look at the volume of water coming out and have someone start the vehicle and idle at about 2000 rpm if that volume has not doubled your pump is bad

My coolant resevoir is full but top coolant hose is empty. Is there a bleeder system?


Here is a basic description of cooling system, the top hose going to engine is the supply hose the bottom hose is the return hose. On your overflow coolant reservoir there is a lower cold level mark and a hot level mark above it also there is an overflow drain spout several inches above hot level mark to relieve pressure if system is overfilled. As to a bleeder system, bleeders purge air from a system to allowed it to become primed (pressure built up) generally on hydraulic systems like brakes or pneumatic systems like a diaphram pump for example. the only drain available is the petcock valve at the bottom of the radiator used to drain coolant. Now to your top hose being empty, you can remove top hose to engine have a garden hose running into radiator and if radiator cores are not stopped up water should flow freely from hose if not radiator is clogged. If you have water flow now you can pressure test system it should hold between 15-18lbs pressure constantly otherwise check all hoses/clamps etc (if leaks were present before replace faulty component/s) your vehicles water pump circulates coolant and is what pressurizes cooling system. A faulty thermostat will also restrict coolant from entering the engines coolant passageways if it doesn't open and your vehicle would overheat soon after, but you should still have coolant in upper hose when engine is running regardless. If you can add other info like your vehicle is running hot or coolant light coming on I can narrow it down for you.

I can't seem to find the thermostat in my 2000 Chrysler LHS 3.5 L Is it in the manifold at the end of the upper radiator hose or elsewhere? I've seen so many answers and haven't yet found a solution. A...


If you were to take the upper radiator hose off the engine, and look into the resultant hole, you would see the thermostat.

The thermostat on all cars blocks water leaving the engine and going to the radiator, until the thermostat warms up enough to open.

While the thermostat is closed, water circulates through the heater hose, straight back to the inlet of the water pump. This circulation prevents hot spots, distributing the heat evenly to warm the engine up, and also brings that warmed water to the thermostat.

When the t-stat gets hot enough to open, water leaves the engine instead of circulating through it, and that allows cool(ed) water to flow from the radiator through the bottom hose to replace the water that left through the upper hose and t-stat.

The stub that the upper hose attaches to on the engine should be part of a small housing that is bolted to the engine. Removing that housing is how you remove the t-stat.

The heat did not work when i got my 98 ford taurus i changed the thermastat, and theres no water in my floor so what could it be?


Heater core could have build up in it and have a restricted flow....thus your heater would not be blowing as hot of air. You should do a pressure test on your cooling system to see if you are loosing any coolant...and where (if your water pump is loosing then you would not be getting the proper circulation).

You can also do a check by starting the engine cold. Grab the upper hose and you should not feel any coolant flowing through it. When the engine begins to get uo to temp the properly working thermostat will open and you will begin to fell coolant flow through the upper hose. When the engine is up to temp your upper and lower hoses should feel hot.
