Will not have a thermastat make suv overheat its 2001 ford escape


No.
Leaving the thermostat out will not make the engine run hot.
Some possible causes are low coolant, faulty water pump, or leaking head gasket.

1996 M.Carlo Z-34 3.4ltr v-6 Changed noisy water pump, added fluid, engine warms up but there is no coolant flow. Changed thermostat, still no coolant flow when engine is running and warmed up. Also n


You may have gotten the wrong pump. Some are reverse rotation, depending on your belt routing. Remove the thermostat and see if the coolant is flowing in the PROPER direction.

2005 jeep liberty blows cold air through the heater.


Either you are low on coolant and there is air in your heater core, or the thermostat isn't working properly, or your water pump is going out.

Why does my car overheat and i get no heat in car


Have you recently changed your engine coolant? Have you checked your engine coolant? If you just changed the coolant you probably have an air lock in the system and it needs bleed out. To do this i would need to know more info about the vehicle. Another possibility you could have a coolant leak, IE the water pump, radiator hose, heater hose leak. with low coolant the radiator can't do its job and cool the engine. You could also have a broken water pump impeller. No impeller no engine coolant flow threw the engine and heater core.

Coolant will not cycle threw the heater coil


its plugged, take off both heater hoses (at the engine) and hook up your water hose and try to flush it in both directions, water should flow easily both diretions. clogged cores are caused by coolant that is not protecting the engine.

Heater works but .no heat is coming from vents.. dolorescastellon11@yahoo.com


check your coolant level if the coolant level is low it will not circulate coolant through the heater core witch will give you heat .or it my be the heater control valve not working ,(this allows coolant from the engine to flow through the heater core.if coolant is low you probably have a coolant leak.

Engine light is on the heater does not always throw warm air is it the thermostat and is it an easy fix?


Hello,
Yes, it could be the thermostat, and yes it is pretty easy to fix. Here's how.

The location of the thermostat for most vehicle.

Stand in front of the car with the hood open, you'll see a black hose hooked to the upper side of the
radiator.( about 2 inch in diameter, newer vehicles about 1 and 1/2 inch, and newer small cars
about 1 and 1/4 inch. ) Follow the hose to the other end, it connects to the thermostat housing.
The thermostat is inside of the housing.( the hose usually goes to the air intake manifold, but some housings are on the side or back of the engine. )

How to test the thermostat in most vehicles;

Make sure the heater is off, start the engine and let it run for 6 to 8 minutes, ( this will allow the
engine to reach, " normal operating temperature "), from the inside of the vehicle turn the heater
temperature on high and turn the fan speed on high.
1. Listen very closely for a click sound from the engine, ( most thermostats make a click when
they open )
2. Watch your temperature guage, it should begin to lower as the coolant starts to circulate.
3. Usually within a few minutes the radiator fan will kick.

To replace the thermostat in most vehicles yourself;

Remove the hose from the housing, then remove bolts from the housing and lift the housing off
to access the thermostat. Pay attention to witch side is up on the thermostat that you remove, the
new one will have to go in the same way. Also look at the temperature rating that is stamped into
the thermostat that you take out, and make sure the new one has the same temperature rating.
(failure to do so can cause false readings by some sensors, and may start triggering error codes)

Install new thermostat, right side up, put housing back on and bolt back down, hook hose back on
to the housing. Check the coolant level. Start the engine and let it run for 6 to 8 minutes to reach,
"normal operating temperature", and look for any leaking. before you turn the engine off turn your
heater wide open and listen for a click. Most of the time when a thermostat opens you can hear a
click and may hear the coolant flowing through the system. Shut the engine off, wait for it to cool
down and then check your coolant level one more time. ( do not fill all the way up, only fill to
FULL line on resrvior.)

What the thermostat does;

It seperates your coolant into two parts. The first part is in your engine, the second part is in your
radiator and the coolant reservior. When the coolant in the engine reaches the temperature rating
on the thermostat the thermostat opens to allow the two parts of coolant to change places. Now
the cooled coolant in the radiator and reservior flows into the engine while the heated coolant flows
from the engine into the radiator and reservior to be air cooled by the radiator fan.

I hope this helps you.

99 300m overheated--replaced thermostat still over heating. ?? How do I add antifreeze to the engine


hi, you can add two ways, one is threw the the over flow tank and the other is threw the radiator cap. i would flush the radiator soon. you may have sludge build up that is interfering with the flow of coolant.

It sounds like your heater core is stopped up, or be sure your coolant is flowing, and picking up heat from your engine...Thermostat, water pump, etc.
