Find the highest hose and loosen of the clamp to release the air from the system
many have a bleed screw at that point as well
have a compression test done and have a coolant pressure test done to check for leaks

SOURCE: Honda Civic LX 1995, replaced

First check for the rad fan working. It could be the Fan relay, bad ground connection or coolant temp sensor (commands the fan relay). If not, check for little tiny bubbles in the coolant. Do this by running the vehicle with the rad cap off. Make sure there is no pressure in the cooling system first or you will get burned (squeeze rad hose, should be cool and easy to squeeze). Look into the top of the rad and watch for these tiny little bubbles. If they are present, you will need a head gasket.

SOURCE: '90 Subaru Legacy overheating....

cool air and overheating point to low coolant level. Do you have a bleeder valve near the thermostat? You may have air trapped in the system. If no air trapped, the radiator may be plugged up not allowing proper circulation of coolant.

My 2006 Caravan temperature gauge goes to red - engine is not overheating. Kick it into a lower gear (automatic trans) and the gauge comes back down. Is it likely the coolant sensor?


Could be.. is the system FULL? Air in it can cause some odd things. When engine and coolant are COLD (as in after sitting over night), open the radiator cap. Top off the overflow res with a 50/50 antifreeze / water mixture to HOT mark. Start engine, turn heat to hot and fan to high. Top off RADIATOR with same 50/50 mixture slowly & gradually. As the coolant circulates, it should bring any AIR trapped in the system (from heater core & engine block) to the radiator where you can replace it with the 50/50 mix. Once the coolant is HOT and stays level - about an inch under the opening, close the radiator. Monitor the overflow res and add as needed. Good luck!

I have a 2006 Cadillac DTS my temperature gauge goes up and down but the car never overheats. When the needle is in the red the car putters but when the needle fall it rides smooth again


Actually, by your very description of the symptoms the car IS overheating. The temperature gauge should NEVER be "in the red" as this is too hot for the engine. The "puttering" you describe is the engine laboring to stay running in the overheated condition. This is shortening engine life dramatically. It sounds like you may have a thermostat that is not opening completely, or a cooling fan that is not operating correctly. If a fan problem it could be either the fan motor itself or the coolant temperature sensor that turns the fan on. It is imperative that you get this looked at IMMEDIATELY. The engine on your Cadillac has aluminum heads and they are easily warped or cracked by heat. A third problem you could have is a low coolant level. Never trust the sensors in the overflow bottles. If the coolant in the reservoir gets depleted, then the system develops air pockets which cause overheating and erratic gauge operation. If this is your problem, topping off the reservoir and purging the air in the system should clear things up. Be advised, however, you should also be on the lookout for system leaks if this occurs.

Temperature guage goes to high, but it doesn't appear that the van is overheating (no steam/fluid leaking) Radiator & thermostat were recently replaced. Guage will jump to high when idle, but...


FLUSH RADIATOR, HEATER CORE AND ENGINE BLOCK.ADD 50 / 50 ANTIFREEZE AND WATER ALSO REPLACE RADIATOR PRESSURE CAP.IF TEMPERATURE GAUGE STILL STAY HIGH THE ENGINE COOLANT TEMPERATURE SENSOR COULD BE FAULTY.

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


YOU NEED BLEED AIR OUT THE COOLING SYSTEM.WAIT TO ENGINE COOL DOWN.YOUR VECHICLE YOU HAVE TO POUR COOLANT IN THE COOLANT OVERFLOW JUG UNTIL COOLANT LEVEL STAY AT THE FULL COLD MARK.THEN START ENGINE LET IT IDLE A FEW MINUTES WATCH COOLANT IN THE OVERFLOW JUG WHEN IT DROPS ADD MORE COOLANT UNTIL COOLANT LEVEL STAY AT FULL COLD MARK.WHEN COOLANT LEVEL STOP DROPPING IN OVERFLOW JUG.SCREW RADIATOR CAP BACK ON OVERFLOW JUG WATCH ENGINE COOLANT TEMPERATURE GAUGE AS COOLANT TEMPERATURE START CLIMBING TURN OFF ENGINE LET IT SET A WHILE KEEP FROM GETTING SCALDED.TAKE LARGE RAG PLACE OVER COOLANT OVERFLOW JUG CAP SLOWLY OPEN RADIATOR CAP A LITTLE AT A TIME UNTIL PRESSURE RELEASE.REMOVE OVER FLOW JUG CAP.ADD MORE COOLANT UNTIL COOLANT LEVEL AT THE FUL COLD MARK ON THE OVERFLOW JUG.THEN SCREW CAP BACK ON THE OVERFLOW JUG.START ENGINE LET IT IDLE AGAIN WATCH ENGINE COOLANT TEMPERATURE GAUGE WHEN TEMPERATURE GAUGE START CLIMBING.TURN OFF ENGINE WAIT A WHILE.CHECK COOLANT LEVEL IN THE OVER FLOW JUG.DO THIS PROCEDURE UNTIL THE COOLANT LEVEL IN THE COOLANT OVERFLOW JUG STOP DROPPING AND STAY AT FULL COLD MARK,WHEN THE TOP RADIATOR HOSE GET HOT THERMOSTAT OPENING AIR IS OUT THE COOLANT SYSTEM. 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.

Need to know if i need to bleed the cooling system, after installing the radiator?


ADD COOLANT IN THE COOLANT OVERFLOW JUG UNTIL COOLANT LEVEL STOP DROPPING AND COOLANT LEVEL STAY AT THE FULL COLD MARK.PLACE COOLANT OVERFLOW JUG CAP BACK ON JUG.CRANK VECHICLE UNTIL ENGINE START WARMING UP. STOP ENGINE WAIT FOR A WHILE UNTIL COOLANT COOL DOWN TO KEEP FROM GETTING SCALDED. USE A LARGE RAG OVER THE OVERFLOW JUG CAP OPEN OVERFLOW JUG CAP A LITTLE AT A TIME REMOVE OVERJUG CAP CHECK COOLANT LEVEL ADD MORE. COOLANT IN THE OVERFLOW JUG.THEN START VECHICLE AGAIN.LET ENGINE IDLE UNTIL TOP RADIATOR GET HOT.THEN THERMOSTAT WILL BE OPEN.WHILE ENGINE IDLING WATCH THE TEMPERATURE GAUGE IN VECHICLE IF TEMPERATURE GAUGE START CLIMBING IN THE HOT ZONE.TURN OFF VECHICLE LET IT SET A WHILE THEN USE LARGE RAG REMOVE OVERFLOW JUG CAP.ADD MORE COOLANT, PLACE CAP BACK ON START VECHICLE AGAIN KEEP DOING THIS PROCEDURE UNTIL TEMPERATURE STOP CLIMBING HOT ZONE.AND WHEN COOLANT LEVEL STOP DROPPING IN THE COOLANT OVERFLOW JUG.AIR IS OUT THE SYSTEM, BUT KEEP COOLANT LEVEL IN THE COOLANT OVERFLOW JUG AT THE FULL COLD MARK.DONT OVERFILL.DONT LET COOLANT OVERFLOW JUG RUN DRY IF SO AIR WILL ENTER COOLANT SYSTEM BECAUSE COOLANT LEVEL WILL BE LOW ENGINE WILL START OVERHEATING.
