What you will probably find is a common problem with many vehicles when the water system is refilled you get an airlock in the heater matrix it's self, this is located inside the vehicle but the rubber hoses are outside x 2 close too the back of the engine compartment, just get the temperature up and hold these two pipes to see if they get hot, if the top hose gets hot but the bottom one does not you have air in the system, Now what you need to do is release the bottom hose been very careful not to burn your hands, and allow the water too run through for a few seconds and replace, Then check to see if the bottom hose gets hot, if it does great, if not repeat process

Car blows out cold air but steam out the bottle

I would install a new thermostat. The only way to check a thermostat is to heat it up in a pot of water on the stove and make sure it opens and closes. Make sure it's in the right way, and make sure the radiator is full. You may have to loosen a heater hose to get the air out of the system. I usually let them warm up with the cap off to make sure it's all "burped" out. Once you have everything full if it still overheats, you may have a water pump problem. Squeeze your rad hose right shut if you can. When you release it, you should feel a gush of coolant go through it. If you don't, your water pump may be no good, and will have to be replaced.

95 Jeep Wrangler YJ...No heat, temp at about

It should be 200 degrees. If your running cold the only thing that regulates temp is the thermostat. If it is indeed 150 degrees thats why you have no heat.

If you replaced the water pump and the radiator for this condition then it was a waste of money. If you had a water pump or radiator problem it would overheat.

The fact that your blowing cold air tells me the that you really are 150 degrees or the heater core is plugged.

The car over heats in a matter of minutes. We put a new water pump on but we need to know where the fans sensors are? Cn you help?

If it's overheating in a matter of minutes from cold, it is probably not the fan or fan switches. If the gauge goes up that fast, it is often because of air in the system. When hot air hits a water sensor, the gauge will skyrocket. make sure the radiator is full and open any bleeders in the cooling system (if it has any) to purge all of the air out. Also, try turning on the air conditioner -- that should start the cooling fan -- to see if that makes a difference. One more thing: just because a part is new, don't assume it's good. I once saw a car overheating with no heat and a full radiator (classic water pump) with a new water pump on it. We took it off and realized the impellor (blades) was loose on the shaft! Good luck.

Over heating, blowing cold air at times, air in lines

the installation of you water pump is probably not in the right angle or try changing the timing belt as well.

Causes for overheating in a 1997 oldsmobile aurora

Do the fan(s) come on when hot? Blow out the radiator core with compressed air (from the engine side) to clear it of bugs and other debris. Make sure the radiator is full to the top (when cold) and check the radiator cap seal rubber and the over-flow tank and tubing for leakage. It's possible that the water pump impeller is slipping on it's shaft and not pumping water properly. Remove the thermostat temporarily and remove the radiator cap. Remove some of the water so that the level is somewhat below the cap bottom, then start the engine and watch for rapidly moving water. That will show that the pump is moving water well. Allow the engine to heat up and keep track of the water movement. Shut the engine off at low end of 'normal' on the temp gauge and replace the cap so that it doesn't blow out boiling water into your face. Replace the thermostat and top up the water when cold again.

2000 olds bravada the heat dose not get hot or cold stay the same i switch it to hot or cold dose not matter what could it be

Hello the bravada and the s10 blazer are bad about the heater cores air locking or either stopping up. Disconnect the heater hoses at the firewall and run a water hose to the inlet then try the outlet until the water is clear of debris then reconnect and refill with coolant remember 50/50 coolant water. Pure coolant will freeze and so will pure water. Thank you
