SOURCE: Why is the return hose for the Raddiator hard.

At normal operating temp when the coolant system is pressurized, the top hose should be hard.

SOURCE: car overheats loosing water changed

IF the heater core was leaking you would notice it inside the car. You would notice the smell of coolant inside. Also your windshield would probably instantly fog up when you turn the heat on. Do you notice puddles of coolant under the car? You can buy or possibly rent a cooling system pressure tester which is simple to use. You remove your radiator cap and itstall the tester and pump up the cooling sytem to what ever PSI your cap is rated for and let it sit for a few minutes. IF the PSI drops that means there is a leak somewhere and you should be able to find it if you see any puddles under the car. If not you may have an internal leak such as a bad head gasket or cracked head. Or possibly a bad intake manifold gasket. Does your oil look milky. If so that means there is coolant in it? Do you notice excessive steam or white smoke from your exhaust? If so I would suspect a head issue.

Overheat problem on a 06' Hyundai Santa Fe, overheated after a 30 mile trip and some shopping. Radiator Fan not on.


Thermostat is best guess and cheap to try. Test the old one by boiling in water. If it opens, the problem may be clogged radiator or possibly busted water pump, blocked passage.

I have a 96 grand marquis i just changed the radiator and the coolant is not flowing through the hose to the thermostat and the hose at the bottom of the radiator what can i do?


check water pump with car OFF try spinning the fan if spins free check thermstat if not i would say change water pump i would suggest changing them both your looking about 50 bucks for a water pump and about 10 on thermostat (i would get a fail safe, if it breaks it locks open so theres no engine problems)

Need manual for,or, info on overheating radiator,(radiator light comes on) but radiator is full, no leaks, and thermstat seems to be opening/closing. ?????????


If the thermostat is good and the radiator is full the only thing left is the water pump. I recommend the Haynes repair manual for addressing the replacement of the water pump.

2003 towncountry over heating.replaced rad and thermstat but still over heating what the f cuold it beit has a 3.3 ....the rad had side blown out to begin with replaced it with upper,lower hoses and...


1. With what you have replaced, the only remaining credible explanation is the Water Pump. If the Water Pump is not operating correctly, this will cause overheating. The Radiator -"side blow out"? Did the radiator cap you have on not work. Overheating should cause fluid = steam to blow out the cap and not blow out the side of the radiator.
2. One thing you can do before replacing the Water Pump is to flush your entire system. There could be a blockage in the system. These flushing kits are available at most stores (Walmart or Autoparts Stores) and you can do it yourself.
3. Was the Engine Coolant Temperature Sensor (mounted near the thermostat) also changed out? If this was malfunctioning it could be giving you a false reading.
The Water Pump is the likely culprit if the Van is truely overheating.
Let me know if this helped, or if you have additional questions or information. Feel free to contact me at FixYa.com!

My car is over heating when i shut it off the coolant resivoir is boiling and brown in color


It sounds like a faulty thermostat. Follow the main radiator hose to where it hooks onto the engine. The thermostat is located inside that housing. But is the cooling fan operating? Do you see any leaks at the radiator, hoses, or water pump? The water pump should have a "weep hole" and coolant will be coming out of it if the water pump is defective. Hopefully, it is the thermstat, that is an easy fix. Hope this helps and good luck.

99 Taurus heater not working.


sounds like you may have an air bubble trapped. Try loosening the radiator cap & running the engine at 1500 rpms till the thermstat opens & see if you can "burp" the air out. You may lose a little coolant this way. shut off car & recheck coolant in radiator and reservoir bottle. Just because reservoir is full, doesn't mean radiator is full.
