SOURCE: radiator cool, engine temp = 140

sounds like your radiator is clogged, it will bring problems to you soon, you need to flush it really good, i dont think you need to replace it but it sounds like a typical clogged radiator, have it flushed, it you cant ur gonna need to replace it soon, if you keep running that car it might lead you to a temp problem while runing and u might end up hurting your engine...
u also need to check if your thermostat is working properly. go on google and look for the procedure, ur gonna have to take it off and do a test with hot water and a thermometer and see if its working properly.
hope this helps.
have fun!

SOURCE: I replaced the top radiator hose, and added

The hot running engine may be the thermostat or blocked rad......sometimes rad cap.
If running hot only at low speed....it may be perhaps the rad fan is not coming on.
On the hot right side heater air hot and left air cold....if you do have dual zone controls..... it is a 99% chance your actuator for one side is bad.
Open the glove compartment....all the way....you may have to bend the tabs in a bit or remove the screws from the bottom....look in and to the left....on the heater assembly you will see the 2 controls on the top of the air duct work.
The right side (passenger side ) is usually on the side to the rear of the car.
Buy the replacement for whatever side is not responding with heat and cold as you select on the heater controls.

There is a blockage or leak in your cooling system. That may come in a few different forms:
Incorrectly installed thermostat
Water pump not functioning - you may see water dripping from the pump or a stain from the hole under the water pump.
Severely coroded hoses/coolant passages - if the fluid is brown and the inside of the radiator rusty
External leak - you would see fluid on the ground Internal leak - you would see steam/white smoke from the tail pipe or water in the oil (may look like chocolate milk or not), if the oil level is extremely high this would be a good indication
heater core bypassed

Runs hot sometimes. Top radiator hose hot, bottom cold. What's wrong?


top hose should be hot, all water from engine goes through upper hose, then radiator to cool and out lower hose.

Started running hot,replaced thermostat and still runs hot.Top radiator hose is hot bottom is cold.


Did you put the thermostat in backwards? If you did, it wont open when hot. Thermostats look pretty much the same - with some minor variations. It's important to note the the side with the spring should be facing the (hot) engine and the other side facing the (cool) radiator as shown in the image below. If the spring side doesn't get hot - it won't open to let hot water from the engine flow to the radiator for proper cooling.

How do I get the front heater to produce warm, hot heat from the blower? for 2003 kia sedona


First I would check your radiator fluid level, sometimes being low can have this effect. Usually the rear heaters sit at a lower level and so keep working. If that is fine, then you probably have an issue with the diversion door or controller that controls the hot/cold mixture.

My 2002 buick century is loosing coolant fast. When car isn't running around 60-70 mph is seems to heat up more than normal and no heat or ac will occur. Should I replace the thermostat? I noticed the fan...


it sounds like one of several problems radiator needs flushed , water pump is bad or going, thermostat is bad, pin hole in one of the hoses, cracked head, hole in radiator, hole in heater core.if core is leaking you will notice water on the floor inside the car on pasenger side. if radiator has hole when you fill radiator with coolant it will leak froom fins sometimes only when hot. thermostat bad your car will read hot and or cold always. if stuck open cold, if stuck closed hot, after about 15 20 mins of running engine will cause radiator to boil over to over flow tank.never open radiator cap when engine is hot :) burn hazard.if pump is bad or going will notice gauge reads hot intermittent or always. will boil in to overflow tank. if head is cracked will notice water comming from side of engine block or in oil when you change oil. if radiator needs to be flushed will notice scale or gunk on radiator cap
(if you think you need help or do not have tools to perform please take to a machanic)

I replaced the top radiator hose, and added coolant it still runs hot and left side air is cold, right side air is hot


Sounds like 2 different issues. Change the thermostat and then check the heater core valve for the left right issue.
