Why does my tempurature get higher after i turn on my air conditioner


an ac unit has a condenser in front of the radiator that is used with a fan to remove the heat generated by compressing gas back to a liquid
That heat is now flowing hack through an already hot radiator so the air can no longer cool the radiator coolant as well
indicates , fins on the radiator core are falling off, blocked radiator cores
besides the fact that it take from 3-5 hp to drive a compressor that extra load is also adding heat into the radiator
Take it in for a radiator flow test and fans operation

Why Temperature while iddling it goes over 90% but while driving it goes lower than 35%


Check and make sure your cooling fans are operating. Air flowing thru the radiator is what removes the heat from the coolant. If the fans are not pulling air thru the radiator when the vehicle is not moving the temperature will rise until the vehicle over heats. But when the vehicle is in motion air is forced thru the radiator removing the heat from the coolant and thus, the vehicle operates at normal temperature.

Over heats when driven and not standing still, why?


There are a few probable causes but my best guess is that you have a stopped up radiator. At an idle, the engine isn't working so id doesn't generate much heat. The harder the engine works, the more heat it generates. The heat has to go somewhere, so the radiator is designed to dissipate the heat by air flowing by the cooling fins which are attached to the tubes which carry the coolant through it. As a radiator gets older and it is not maintained, it is quite common for the tubes in the center of the radiator to become restricted or even clogged. This means that the only part of the radiator which is actually working, is the outer portion which is not that effective because most of the air flow is designed to go towards the center of the radiator. There are places which can flush radiators but they are not very effective when a radiator gets to the stage you are describing. The flushing of a radiator is a preventative maintenance service to eliminate a problem like yours from occurring. Odds are you are going to have to replace your radiator. One other probability while rather unlikely, would be a rather large obstruction keeping the air from flowing through the radiator.

I replaced my water pump for my 2006 buick lucerne and now theres no heat


Hope you didn't break a nail.

There is a air pocket in the heater core, you just didn't burp it right.

Try this

  1. Open the hood of your car. Secure the hood with the safety handle. If you have a newer car, you should have a bleeder valve on the front of your radiator. Check in your owner's manual for the location of this valve. If you do start your car, open the valve with wrench and let your car heat up. The excess air will bleed out of your cooling system. Keep your car on long enough to give the (trapped air) time to bleed out of your system.
  2. Let your car cool down. Once the car is cool, take off the radiator cap. Did the level of the radiator fluid go down? If it did, it means you bled the air out of your cooling system. Replace the radiator fluid, turn on the car, and let it run. Replace radiator fluid as needed.
  3. Step 3 (above) is the way you will remove air from your cooling system if you do not have a bleeder valve on your radiator. You will leave the cap off the radiator. You will run your car until it heats up. As the air dissipates, the radiator fluid level will go down. You will fill up your radiator fluid to the correct level. Be careful because the heated radiator fluid will be hot. Always wear leather gloves and safety goggles when working on your radiator.
  4. Once the air dissipates and you fill the fluid, shut off the car. Let the car cool down. Once the car is cool, put the radiator cap back on the radiator. You may have to put more radiator fluid in the radiator. The level may fall as the car cools down. Now it is safe to drive your car. You have removed the trapped air from your cooling system.
Tips:
Always wear gloves and safety goggles when working on your radiator.
Radiator fluid gets very hot when heated.
Check radiator fluid periodically.

I have a 2000 chryler concorde with no heat. I changed the thermostat.I 've checked the coolant. The blower is working but only cold air. Any solutions


if you have changed the thermostat. did you bleed air out of system, if air is trapped in system it will not heat right! drain radiator and flush it good, but when refilling turn heater on high heat. then bleed air out when refilling system. most all cars have a bleeder for air. if in doubt, call any auto parts store to find out where yours is. if air is in system you will see bubbles appear from bleeder. also when flushing engine, make sure you start vehicle so it circulates through engine as well as refilling system. if the upper radiator hose gets hot then check for heat from car if it is ok! close bleeder and make sure radiator is full. I think the biggest culprit is air trapped in system. before starting the flush, be sure its not caused by low coolant in radiator. have a good day!!

New thermostat fitted radiator cap had tested for blown gasket sees ok. Radiator looks very clean inside. Runs fine for plus munis 40 km [hard driving) and suddenly overheats pushing water into...


The radiator sheds heat at a specific rate. Increasing air flow increases that rate a bit, but even with increased air flow, there is a specific rate.

When you start out, there is a "cold reservoir" in the radiator — without shedding any heat at all, for a while the cold water in the radiator will keep the engine cool.

If the heat from the engine exceeds the heat the radiator can shed, as soon as the radiator water hits the temperature of the engine, you will have overheating.

If you have a head gasket leak, you are injecting heat directly into the water, heat that ought to go out the tailpipe.

If some of the tubes in the core of the radiator are not flowing, the ability of the radiator to shed heat will be diminished.

I am thinking it is either a head gasket leak/cracked combustion chamber, or a radiator that does not flow water through all the tubes.

A lean fuel mixture will generate a lot more heat than one that is richer. The coloration of the spark plug insulators can be helpful in assessing the mixture.

Blower is only blowing vent air no heat, was working yesterday now is not.


radiator full? Thermistat stuck open. extremely cold and too much air flow on radiator.?Does it over heat at all? Back flush heater core and radiator and replace fluids, block off part of radiator in extreme cold areas. Check controls to be sure they are opening and closing correctly

2008 Impala heat problems


remove the radiator cap and let the car run for 30 minutes to let the air out of the heater coil, these radiator caps on the 2008 Impala will not bleed off, while running notice if air bubbles air slowly rising to the top of the radiator cap, re-install cap and see if this fixes problem, we also purchased a new radiator cap, this fixed my wifes car.

1998 S10 heat wont work sometimes


When you say the heat doesn't work are you meaning the fan doesn't blow out hot air or just doesn't blow out any air? if it blows cold air sometimes when you have the heat on then it could be poor circulation through your radiator or a weak water pump. make sure your radiator is clean on the inside, not too corroded or nasty inside. You can buy a radiator flush thing from wal-mart or any auto parts store. See if it helps.

No heat


if you replaced the thermostat, you have an air bubble trapped in the engine. So, you don't have any coolant running through the heater core, therefore no heat.
sometimes hard to "burp" air bubble. Try this. Park park facing uphill and jack up front of car too. You want to get radiator opening higher than top of engine. Then remvoe radiator cap (cold engine), fill radiator, then fill coolant reservoir to full point. Install radiator cap but leave it loose so air can escape. Start engine until upper radiator hose going into radiator is hot. This should burp air. Repeat a few times while adding coolant mix (50/50 antifreeze) to keep radiator full. Be careful not to remove radiator cap when engine is hot.
lwt us know how ou make out. There is a more complicated procedure but you need tools and knowledge of where air bleed is on top of engine
