I would check to see if the radiator fan is coming on when the engine starts getting warm.

Car overheating


Two things to check:

1. Make sure you do not have an air bubble in your cooling system. Easiest way is to park facing uphill and let the car cool off. Remove the radiator cap, start the car and let run until the thermostat opens. If there are air bubbles in the cooling system the should be forced out. Top off fluid.
2. Are you sure that the cooling fan is running? When the car is getting hot, open the hood and make sure the radiator fan is actually turning.

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 .

Hi have a 2004 freestar I changed radiator-, water pump , thermostat, engine coolant if I drive on flat street my van runs good temp is normal but if I go uphill the gauge goes up to almost red once I...


Sounds like a faulty temp guage/r a strange malfuntion in a sensor to me as well, only doing it when it going up hill really makes no sense for the way the cooling system works so I doubt that its actually running hot, which is likely why he asked about the gurgling noise, it would force water back into the resivoir if it was running hot assuming that the thermostatic radiator cap is working properly.

Run hot chang thermostat-water pump flush radiator


i would change your coolant temp senosr as it controls your fans and tells them when to cut on and off if you have a belt driven fan replace your fan clutch

What are you going by to say it's overheating , temp gauge ? Have you test to see what the actual temp. is > Hook - up a scan tool ,what's the PCM - engine computer seeing for engine temp. ? 223 degress the PCM should turn on the cooling fan . You could buy a Non-Contact Infrared Thermometer With Laser Targeting at harbor freight ! Radiator very hot ????? What is the right temp .

Could be a bad temp gauge . Is the coolant surging inside the cooling system ? Does it have a radiator cap ? Have you replaced it ?

Keeps running hot change thermostat, fan, moduler


if fan turns on and nothing is leaking try to find a thermometer and check the radiator in different areas sometimes they clog up and only a few vanes are open and not cooling it off properly.youll find cold spots the temp in different area should be the same +or - 10 degree one side to the other.

check the fan and water pump one of these is possibly ur problem when ur at idle there is no heat load and the radiator can dissipate that when ur driving causes more heat if fan isnt working the car wont cool same if problem is water pump at idle pump may be able to move some of the hot anti-freeze but when driving may not be pumping it thru radiator to cool

Water pumps can stall out, but do you have air trapped in system.
Had you recently had the system "open" to replace hose, thermostat, temp sensor. Some Ford and GM have a bleeder screw on a high point in cooling system to bleed out trapped air.

Check your trans fluid color. Since the trans cooler is built into radiator (automatics)

IF the engine is overheating the trans CAN overheat
IF the trans is overheating the engine CAN overheat

They share the same cooling source and trans fluid gets hotter than oil, but yet it has a wimpy cooler built into radiator. Maybe add trans oil cooler to system.

Also outside temp affects the cool down rate of the radiator, ie...hot air trying to cool down hot radiator/engine is less effecting than cool air cooling hot radiator/engine
