Rad hose issue. Did u put the new thermostat in right? Did you install the right temp stat? Is ur water pump working. Is the rad clogged. Fins clean and straight. No kinks in any of the hoses is tje expansion tank hose good to go. Rad cap function ok?. As for the stalling this could be the cp controlling this as its reading over heat. So if it reads over heat it shuts the fuel pump. N stuff off this killing the car saving u an eng. Fix the issues first then maybe it will run better. Also is the fan blades facing the right way if u removed them? Hope this helps.

hi jasso, I would recommend checking the water pump if you see no flow in the radiator. Make sure when you fill up the cooling system, that you fill it cold, and that the vent screw in the radiator is loose. fill system until fluid comes out the vent screw. tighten the screw, start the car and have someone run at 1500rpm and check for flow.also, make sure that you have your temp setting full hot and blower on middle speed so that you don't trap air in the heater core.

SOURCE: Bublling in the thermostat housing and very hot upper radiator hose

I recommend flushing the radiator thoroughly if not done recently. there seems to be some sort of blockage in the radiator at this time. if you get lots of metal fragments that are flushed out during this flush, i will then recommend a rebuild on the radiator or replacement of the radiator. make sure the cooling fans are cycling on time as well.

SOURCE: wont keep idle, car stalls out

I had this same problem on my 2005 monte carlo, took mechanic a while to figure out it was the idle air control valve. They also replace the idle air control motor.

SOURCE: 2002 dodge 1500 Changed radiator, thermostat, and hoses. No heat

Why was radiator replaced?Did it have heat before ? If it was plugged, the heater core may also be plugged. Try flushing it with a water hose in both directions. I dont know why the botton radiator hose would be cold, the radiator should be a uniform temp and the air coming through the radiator should be HOT, when the engine is at operating temp. What condition was the old coolant? if it was rusty, the water pump may have lower flow than normal.

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

Scion tc overheating


let the car cool down. feel radiator with coolant.start the car with a/c ON.the fan will tun ON if not the fan or power to the fan is a problem.
if the fan is good monitor the upper radiator hose for building high pressure before the hose is warm(cylinder head gasket is bad)
if the car don't overheat with a/c on(radiator fan switch is bad)
monitor the temperature to about 180*F-190*F and the lower hose will start to warm up. if not thermostat is bad.replace with fail safe one
good luck

88 dodge chadow,overheating and no heat


How long has it been going on? You need to check if you have a bad head gasket. A compression test of the cylinders would tell you. Not saying that's what it is, but that can be a cause of overheating. And it can also be an expensive result of prolonged overheating. That's why mechanics caution against running an overheating engine. If you find the head gasket is good, it will give you great peace of mind, knowing the Shadow's engine warrants a few more dollars in repairs. Compared to the cost of a new head gasket and having the head checked for straightness and for cracks, other repairs for overheating is minimal.
First check the coolant level and keep it full. It could be a worn water pump. Feel for pressure behind the coolant when you squeeze the upper radiator hose for a second or two. The engine needs to be warmed up and running, so the thermostat is open. Try to squeeze the hose closed, then let off and feel for a surge of coolant, and watch the coolant in the radiator for pressure pushing coolant on through the radiator. Kind of a rough test if pump is circulating coolant. You might also try a new thermostat. They are cheap and easy to replace. Clean the outside of the radiator of leaves or dirt. It should be checked for blockage. When upper hose is hot, the lower hose should also be hot or quite warm, just not as hot as the upper hose. If it is, radiator seems not blocked.
Don't worry about having no heat at this time. When the overheating is solved, and coolant level is full, the heater will return.

Usually, hoses pop off if the radiator/expansion tank cap is incorrect/broken. Find out if this "mechanic" changed the cap, if they did, get the old one back or get a replacement from the dealer. I have never gotten a dependable replacement from any parts stores. If they didn't change it, change it anyway and see what happens.

2000 Dodge Durango getting over heated


Never use a used radiator... check electric cooling fan, and air must be purged out of the radiator / cooling system after refilling it, this can be a little difficult. are you sure that it is not leaking coolant from somewhere else, which would cause the overheating.?

I have a dodge grand caravan with a 3.3L engine and it keeps bursting my raidiator,i've replaced it three times in a short period of time,and it does not have a thermostat. hope u can help me.thanks!


If your blowing radiator up you have a coolant issue. The only way to blow a radiator up is for it to be building way to much pressure. The only way to get that much pressure is the engine running way to hot. I would suggest trouble shooting the coolant system. Make sure water is getting thru the entire engine by putting a water hose in the upper radiator hose and see if you get water out of the upper radiator inlet.

I would also check to see if the fans are coming on. If you have 1 fan it should come on when the vehicle hits about 205 degrees. If you have 2 fans one will do what i already said and the other will come on when you turn the ac on.

If you find no issue so far then the water pump is probably bad or the coolant lines themselves are bad. You can check the coolant line by running the vehicle. When it starts to heat up if the hose is bad it will start to collapse. Also make sure your radiator cap is the right pressure for the vehicle and that it is actually good. Its easier to just buy a new for 5 bucks and be done with it. You should replace those caps every 30 k miles regardless.

Remember a coolant system keep coolant from boiling by allowing pressure to build. If the system is not allowed to build pressure then the vehcile will over heat and if it gets bad it will blow a radiator apart.

Overheating..


check the radiator hoses, you might have one that is squeezing in when the pressure builds, with the car running check your upper and lower hoses to make sure they are not pinching anywhere... also you should make sure that the hoses have no build up in them blocking anything.... hope this helps you out

2002 dodge durango overheating while driving, not while idle. not losing fluid, thermostat, radiator, radiator cap, temp sensor, head gasket all ok. why is it only overheating when driving??


you could have a bad hose, check the upper and lower hoses and hake sure they are not caving in on themselves. sounds like it could either be that or you might have something cloging the hoses. run the engine with the hood open so you have the pressure build up, and look at both raditior hoses. see if they are bulging out as pressuer gets built, or if they cave in .
