SOURCE: 97 f 150 runs hot for minutes then runs ok

It could be a faulty thermostat. Did it do the same thing before u replaced the t-stat? It sounds like it's sticking closed, then all of a sudden it opens, coolant flows correctly. I'd consider changing it again. Check to make sure parts store is giving u the correct temperature thermostat also. Maybe it's too high for your Ford, delaying the opening.

SOURCE: 1994 Century Buick Heating problem

It sound like you have a block or plug up heater.If you just used a garden hose that is not a flush .A reel flush is called a power flush it used about 150lb. of air&water mix. Find a Radiator shop to do this. as far as your temp. going up and down you may have an air trap in eng,an radiator run car for 20min without the cap on. I have been doing Radiator work over 34 years

SOURCE: Hey Chevy Minivan heater dont work properly

Chevy made some weak intake gaskets on 3.1 and 3.4. My guess is that the intake gasket is weak and/or leaking and it is letting pressure out somewhere. At idle maybe the system pressure is to little to push hot coolant into the heater core.

My heater is blowing cold air


I'm going to venture a guess here and guess that you're driving a Ford of some sort?

First, everyone needs to STOP assuming it's the Heater Core. It very well could be, it very well could NOT be. You need to go by process of elimination starting with the simplest first, so you don't WASTE money and parts on needless things.

Step 1.) Test the coolant system thoroughly. Hook it up and make sure fluid is being actually PUSHED through the cooling system first. I literally just got done working on a 2002 Ford Taurus that people were telling me the same damn thing, and guess what, good heater core, CLOGGED LINES. Some engines are designed in a way that causes build up, then that build up breaks free and starts clogging the lines and ports. A good coolant flush might eliminate the blowing of cold air. If not, move to step 2.
Step 2.) Check your thermostat. And with that, pay attention to the heat gauge on your vehicle. Does heat stay low? Does it go higher? If lower, your thermostat is stuck OPEN, and will cause LOW temps feeling like COLD air. If stuck shut, well then your car will run a little warm. In either case, it should be replaced.
Step 3.) Check the COOLANT CAP!!! I cannot stress this enough. Most, if not all, of the cooling systems in vehicles come with a PRESSURE cap, and if that cap loses pressure, you lose the ability to move fluid.
Step 4.) CHECK AND REPLACE HEATER CORE. Finally, the step you've been waiting for. Always fun(not really).

Why doi have a winding sound in my SUV in almost every gear


Sounds like a blown head gasket - This will damage the transmission of the SUV if the hoses where blown off the radiator . Had it happen to a car. When the gasket is blown pressure builds in the vehicles cooling system until it builds to a point where it blows the hoses off the pipes or blows up your radiator. The transmission may also have a cooling system that has been damaged from the pressure build up. Get a radiator dude to put a cap on your radiator with a pressure gauge and then run the engine and see if the pressure climbs on the cooling system.

I have 2004 ford f 250 6.0. let me start by saying, it has new head gaskets, new head bolts, new glow plugs, new water pump, egr delete, even new radiator cap, only 6000 miles ago. but now when engine is...


I my experience it is a compression leak into the cooling system probably a crack between the valves or improper torquing of the heads one test to confirm is test the cooling system for hydrocarbon emissions you can do this with a gas analyzer or a block fluid test kit if you uses the fluid test follow the directions exactly or you could get a false reading

bleed the air from cooling system. and make sure its full of coolant. replace thermostat if need be. good-day ! if above fails replace coolant reservoir cap, it may not be releasing pressure as need be. and its over heating. just remove cap and start car to see if it over heats. if it still does, repair as above. and be sure the cooling fans are working. but an improper seal of the radiator cap or pressure malfunction of the cap is an easy (and cheap) source to check first. If the pressure in the radiator is not high enough, the fluid will boil at a lower point and the resulting steam cannot flow through the cooling system.

No my alero is overheating. I have replaced the thermostat and waterpump and put a new cap on reservior and im losing coolant out the overflow

WHEN ENGINE COOLS DOWN.CHECK COOLANT OVERFLOW JUG COOLANT MUST BE IN THE COOLANT OVER FLOW JUG AT THE FULL COLD MARK WHEN ENGINE COLD. DONT .DONT OVERFILL COOLANT OVERFLOW JUG.KEEP COOLANT IN THE OVERFLOW JUG IF YOU LET COOLANT OVERFLOW JUG RUN DRY AIR WILL BE DRAW IN COOLANT SYSTEM CAUSE ENGINE TO OVERHEAT.

I replaced my radiator on my 2004 with a 2.2 and it seems like the thermostat is not opening. It can not get the air out. It seem to just to over heat and push the coolant out. Randy


REPLACE THERMOSTAT IF TOP COOLANT COOLANT HOSE GOING TO RADIATOR IS HOT TO TOUCH THERMOSTAT OPEN. TO BLEED COOLANT SYSTEM FIRST YOU NEED TO ADD COOLANT TO THE COOLANT OVER FLOW JUG UNTIL COOLANT LEVEL STOP DROPPING AND STAY AT FULL COLD MARK.WAIT 3 MINUTES IF COOLANT DROPS ADD MORE COOLANT UNTIL COOLANT STAY AT FULL COLD MARK.WITH RADIATOR OVER CAP OFF CRANK ENGINE FOR MINUTE WATCH COOLANT LEVEL AT OVERFLOW JUG.IF COOLANT DROPS ADD MORE COOLANT IN THE OVERFLOW JUG.WHEN COOLANT LEVEL STOP DROPPING IN OVERFLOW JUG.SCREW BACK ON THE RADIATOR CAP TO OVERFLOW JUG.WHILE ENGINE IDLING WATCH TEMPERATURE GAUGE WHEN TEMPERATURE START CLIMBING TURN OFF ENGINE WAIT A WHILE KEEP FROM GETTING SCALDED.WHEN COOLANT COOL DOWN SOME. PLACE A LARGE RAG OVER THE COOLANT OVERFLOW JUG OPEN CAP LITTLE AT A TIME UNTIL PRESSURE RELEASED, THEN REMOVE CAP ADD MORE COOLANT IN THE OVERFLOW JUG TO THE FULL COLD MARK.THEN REPEAT THE PROCESS SCREW BACK ON THE COOLANT OVERFLOW RADIATOR PRESSURE CAP.THEN START ENGINE WATCH TEMPERATURE GAUGE WATCH COOLANT TEMPERATURE GAUGE WHEN COOLANT TEMPERATURE START RISING TURN OFF ENGINE AGAIN WAIT UNTIL ENGINE COOL DOWN ENOUGH TO KEEP FROM GETTING SCALDED TAKE PLACE LARGE RAG OVER RADIATOR CAP WHICH IS THE COOLANT OVERFLOW JUG CAP OPEN CAP LITTLE AT A TIME UNTIL PRESSURE RELEASED ADD COOLANT UNTIL AT FULL COLD MARK. WHEN YOUR COOLANT LEVEL STOP DROPPING.AND TOP RADIATOR HOSE VERY HOT THERMOSTAT OPEN AND AIR IS OUT THE COOLANT SYSTEM. MAKE SURE YOUR COOLANT OVERFLOW JUG HAS COOLANT IN IT,WHEN ENGINE COOL DOWN CHECK COOLANT OVERFLOW JUG KEEP COOLANT LEVEL AT FULL COLD MARK.BECAUSE IF OVERFLOW JUG IS EMPTY THATS A SIGN RADIATOR COOLANT LEVEL LOW.WHEN OVERFLOW JUG EMPTY IT WILL ALLOW AIR GET IN THE COOLANT SYSTEM AND CAUSE CAR TO OVERHEAT.WHEN REPLACING THERMOSTAT ALSO REPLACE THE RADIATOR CAP ON THE COOLANT OVERFLOW JUG.

I replaced the thermostat in my 1998 subaru forester. How do I know if it is openning when it needs to? How can I test the pressure in the radiator? What should the pressure be in the radiator?Thank...


To test your new thermostat, do the following
1. Make sure your heater is off.
2. Start your engine and allow it to run for 6 to 8 minutes so it can reach the normal operating temperature.
3. Turn your heat tmperature select all the way up, and then turn the fan on high. You should hear the thermostat click when it opens up to circulate the coolant through the system. You may also notice your temperature gauge reading lowering.

The only pressure you may have in the radiator/cooling system is very minimal and caused by the coolant heating up.Whenever pressure starts building , it is purposefully relieved through your coolant reserviors overflow hose. Thats why you should never fill your coolant reservior all the way up. It needs to have 3 or 4 inches to allaw for expansion.

I hope this helps you.

The cars heat is fine then when i start to slow it starts to cool when i am idle it gets colder


you probably have air trapped in the cooling system.

try to burp air by loosening radiator cap with engine cold. Then as it heats up and thermostat opens (upper rad hose will be hot) and it should burp the air. Then shut off engine and top off radator and tighten cap. Keep reservoir full so radiator can **** the coolant into the engine.

This assumes the engine tempstays in normal range. If gauge drops to colder, then replace the thermostat.

What causes high pressure in cooling system?


i can give you a general answer. the cooling sys is a closed system. as the engine warms up pressure is also increased. kinda like how a boiler works, or a pressure cooker. i dont know the figure of how much pressure is produced within an engine that is operating normally. the engine's thermostat. the thermostat of many car engines opens at 195 deg coolant temp, allowing the coolant to circulate. high pressure when considering a car's cooling sys to me is relative. if you try to remove the radiator cap when the engine is at/near/above operating temp you will be burned by the hot coolant under pressure rapidly escaping out the radiator. most pressure that is above normal is caused by an obstruction somewhere in the system. a t'stat that is stuck shut is an example. air pockets within the system will also lead to high pressure within the system. air pockets occur when you refill the system with coolant/water. pouring water/coolant back into the radiator traps air that can circulate throughout the system and you must ensure that these air pockets escape out the radiator, or you risk damaging the engine from excessive heating.

Stupid engine light!!!


is it a V-6 or 4cyl. take it to autozone and have them retrieve the code...I have worked on all models of camrys...many problems can cause this like IAC valve(common on 4cyl) or timing is offset(very common on V-6). Transmission will not cause rough idle. Tacs on these models usually malfunction stemming from distributor cap/coil oil inside or just the tac itself. Hopefully this helps!!
