98 grand cherokee little heat.heater hoses hot top rad warm bottom is cold collant barely luke warm


While it doesn't seem likely, if you've changed, or had the thermostat changed.... I'd say you got a faulty thermostat. I am curious as to what your temperature gauge says the temperature of the engine and coolant is.. If your gauge is showing hot, I can think of two more possibilities... the water pump isn't pumping right... and, if the water pump isn't working right, the problem can be a cracked head or block, which can cause an airlock in the coolant system. Check the coolant or radiator cap.

The temp gauge reads correctly for a while then it starts going from cool to hot faster the water can change temp. I have changed the sensor


try the thermostat, located on the top radiator hose. top side of engine. also does it steam?? does it lose water but no leak, does the heat blow hot? if your heat isnt hot and it steams and loses water you may have a cracked head or head gasket. if you have heat, doesnt lose water and doesnt steam it may also be your water pump. most pumps will leak visibly from the weep hole when running

CAR OVERHEATS AT TIMES. I CAN DRIVE FEW MILES AND OKAY BUT IF I DRIVE LONGER GAUGE GOES TO H. WITHIN THE LAST TWO YEARS I REPLACED WATER PUMP AND THERMOSTAT AND HOSES. SOMEONE SAID THAT SINCE MY CAR SAT SO...


ok this is why we keep reciepts at our house. you have already bought everything you need to fix the problem. we just need to figure out what went wrong. lets start with the coolent level make sure you have plenty of coolent in the radiator. ok you hear the fans go on make sure they are turning. if thats good i would do the cheepest thing first. new thermostat make sure its the right one for your car the auto store can tell you. it could have seized up after sitting. also if you may want to look for that water pump reciept. just because something is new dosent mean that it works correctly, that goes for thermostat also. now if all of this doesent fix it there are 2 more things and it has to be one of them or both of them. [ important ]when you had this work done was the radiator flushed out and cleaned? if not- even if all these parts are changed you still have sludeg in your radiator that can go right into your new pump and clogg it or the thermostat or clogg the radiator itself whitch still may be a problem. i would start with a radiator flush AND a new thermostat. make sure you have fluid circulation if not its the pump again. i hope this gives you help REMEMBER NEVER WORK ON A HOTT CAR LET IT COOL COMPLETLY DOWN A SATURDAY MORNING PROJECT FOR SURE...

Car overheating fluids are full can't find fuse for fans fans aren't comin on till I turn on heT


Could be thermostat is not opining or water pump is failing. I would start by replacing thermostat if that doesn't help then Replace the heat sensor that tells u temp and when fans should kick on. If Ur still having problems I would replace the water pump. But I highly doubt that it's the water pump. It's either thermostat or sensor.

Ok, g35 coupe 06,52k miles Had over heating problem in april 2010,replaced thermostat, all's well. Now Jan 2011 overheating again, noticed upper & lower radiator hoses collapse, changed thermostat...


Heres a couple of things you can check. Start your car and remove the radiator cap,(before it gets hot mind you) when it reaches norm operating temp, look inside radiator to see if water is circulating. If its not moving, its a bad water pump. Also, youre hoses should never collapse, if they collapse when they get hot maybe you need new hoses? Finally, if those dont work, flush out your radiator. Open the bottom cockpit and use a garden hose and let it flush out the system while the car is running, about 10 mins should do the trick. If the radiator looks clean inside then it doesnt need flushed.

Car is over heating changed thermostat water pump isnt leaking or making any noises


Ok well there are a number of possibilities. One to keep in mind is that some water pumps are really cheap and the fins will corrode and rust off leaving nothing behind to actually pump the water. If the pump really is working fine then there are two more possibilities. 1 the radiator is clogged, 2. there may be a head gasket leak. 3. you are sure your gauge is working right? 4. you didnt say what year or kind of car it is.. Is the electric fan working? When the engine is overheating, are both upper and lower radiator hoses hot? If the water pump or the thermostat are failing the upper radiator hose can be hot while the lower can still be relativly cool. If the radiator is plugged or the fan isnt working then both hoses can be Hot. There is also a remote possibility that water passages in the head gasket could be plugged.

99 grand am gt overheating changed thermostat and


try priming the engine block & radiator with water though the hose's & any hose you can squeeze to pump out the air lock with the filler cap off when running, sounds too much air is is in the system & the pump won't work dry.
I had this problem a few times & I ended up practically forcing water into any hose I could re-attach quickly using a garden hose, as the heating system need's priming too !

My 02 Grand am V6 keeps blowing up all my water hoeses. it even cracked my radiator. it doesnt over heat until it brakes a hoes.


you got a restriction in engine block.its full of rust.flush block out by taking the thermostat out.remove the top hose to thermostat then move lower hose to water pump .place a container so the lower hose can catch the water as you flush out block with water hose.flush from the top where thermostat goes flush until you get a good stream of water from bottom is clear.before you start this procedure drain out antifreeze first. flush out over flow jug make sure its not stop up. and change the radiator pressure cap.

Coolant pouring out surge tank


if one radiator hose gets hot and the other doesnt, the the thermostat is shot, but you said you replaced it, it is possible the thermostat has been put in backwards
