It is normal for an engine doing quite a bit of work like this to get hotter when under load. When you say you had the radiator flushed was it done at a radiator shop rather than just back flowed . The top tank should be removed and whilst water is flowed through the core thin steel rods are passed in and out of the individual tubes. Then the radiator is reasembled and checked for leaks. Often the radiator when doing this can be 50% blocked or more which wont cause a problem unless on a hot day or with a big load .

08 Ford Explorer 4.0L - At times the coolant goes through the radiator cap into the recovery tank, filling it, same time temp gauge rises Changed tstat and cap. I think it is a clogged radiator


possible and an accredited radiator shop will be able to do a flow test to check that
unfortunately , it indicates a gasket or cracked problem so have a compression test done to eliminate that
if that test proves good then have the thermostat removed and checked/replaced if the engine runs a viscous fan hub then check that as well
viscous fan hub failure is most noticeable when stopped at lights ( temp gauge goes up but comes back down when moving along the road) temp rises in slow moving traffic , using high engine rpm as in up hill or any condition where the air is not moving through the radiator unless the vehicle has speed
if you have electric fans then the problem may be in the coolant SENSOR unit that sends the temp to the ECM to switch on the fans

2003 chevy trailblazer cooling temp running 230


Smart man using a scanner for the actual temp. Assuming you're not losing coolant....2 things I'd look at here, 1st is you may have air in the system, make sure to purge all the air. 2nd is your fan clutch, I've replaced a few fan clutches in my own Trailblazer. Have had them bad right out of the box brand new. Have had bad brand new fan clutches on 2 of my last Trailblazers. You should hear it engaging especially in stop and go traffic.

2002 dodge stratus overheating when ac is on. what else can i do to fix it?


Is your ac fan coming on when you turn on the ac? If it only getting hot when you turn ac on I'd say your ac fan isnt coming on so check your ac relay and ac fuses. Is your ac blowing cold

1996 dodge ram 2500 runs hot when towing


Hi Big Mike, Have you checked the timing? If you have a petrol engine it could be ignition or valve timing which has gone out. A stretched chain could do it. Like wise for diesel. If the pump has been ******** too much it will heat more at higher speeds. The overheating can also be caused by a cracked cylinder head. The symptoms are those which you've described! Regards John

1996_gmc_sierra Heat gauge started going from 260 degrees back to normal. I replaced heat sensor then thermostat. This summer had complete radiator and cap put in. The gauge says its running at 230 an


My Mountaineer had a similar problem. When driving it, the temp needle would slowly go up and up for like 3 minutes then it would come down within about 30 seconds. Then it would slowly rise again. just kept doing this over and over but it never went too high. My gauge didn't have numbers on it but it would go up about half way (not near the too hot level though) then fall back down to about a quarter of the way on the gauge. Found out that the fan clutch was bad on my radiator fan. It was not engaging and disengaging at the right times. New fan clutch solved the problem and probably saved the engine from overheating eventually if it had gotten even worse.

My temp gauge goes to the third line before fans come on and only the low fan comes on. I already replaced thermostat, engine coolant temp. sensor and radiator flush... any idea why high fans dont come on...


CHECK COOLANT FAN FUSES AND RELAYS. CHECK COOLANT LEVEL.MAKE SURE ITS NOT TOO LOW BECAUSE IF COOLANT TOO LOW . BY NO COOLANT AROUND OR COOLANT SENSOR NOT SUBMERGED IN COOLANT COOLING FANS WONT TURN ON.MAKE SURE YOU HAVE 50/50 ANTIFREEZE AND WATER. CHECK FOR CLAPSE RADIATOR HOSES.CHECK RADIATOR HOSE AT WATER PUMP.IF HOSE LOOK CLAPSE REPLACE IT AND BLEED COOLANT SYSTEM.IF EVERY THING HAS BEEN DONE YOU NEED ENGINE BLOCK FLUSHED OUT.HEATER CORE ALSO COULD BE STOPPED UP.A VERY HIGH MILEAGE ENGINE WILL OVER HEAT.OLD ENGINE LOSES COMPRESSION AND HORSE POWER.PUTTING MORE LOAD ON THE OLD ENGINE WILL MAKE IT OVER HEAT.IF COOLANT LEVEL IS LOW.BLEED COOLANT SYSTEM.START THE ENGINE LET IT IDLE FEW MINUTES WATCH THE COOLANT TEMPERATURE GAUGE.WHEN TEMPERATURE START RISING.TURN OFF THE ENGINE LET IT SET FOR 20 MINUTES.TAKE A LARGE RAG PLACE OVER RADIATOR CAP ON COOLANT EXPANSION TANK SLOWLY OPEN RADIATOR CAP JUST A LITTLE TO RELEASE A LITTLE PRESSURE AT A TIME.DONT OPEN CAP RAPIDLY OR YOU WILL GET SCALDED.ONCE THE RADIATOR CAP REMOVED.IF COOLANT LOW ADD MORE COOLANT IN THE THE COOLANT EXPANSION UNTIL YOU GET TO THE COLD MARK.REPEAT THIS PROCEDURE START ENGINE LET IT RUN UNTIL TEMP GAUGE START CLIMBING A BIT DONT LET CAR RUN TO OVER HEAT JUST IDLE UNTIL TEMP JUST START TO RISE.THEN YOU TURN OFF ENGINE. WAIT 20 MINUTES.THEN USE LARGE RAG OPEN RADIATOR CAP LITTLE AT A TIME. DO THIS PROCEDURE UNTIL THE COOLANT IN THE EXPANSION TANK STOP DROPPING. THEN ALL THE AIR IS BLEED OUT THE COOLANT.WHEN COOLANT LEVEL STOP DROPPING, WHEN YOU DRIVE CAR AROUND.AND TURN OFF ENGINE.WHEN ENGINE OFF CAR SET FOR A WHILE KEEP CHECK ON THE COOLANT LEVEL IN COOLANT EXPANSION TANK. THE COOLANT LEVEL SHOULD BE AT THE COLD MARK IN THE EXPANSION TANK.MAKE SURE COOLANT IS IN THE EXPANSION TANK.IF NOT AIR WILL DRAW IN COOLANT SYSTEM. CAUSING ENGINE TO OVER HEAT.IF BLEEDING AIR OUT THE COOLANT SYSTEM DONT HELP AND COOLANT FANS DONT TURN ON YOU HAVE PCM PROBLEMS.

I have a 2003 subaru outback 2.5 have had head gaskets replaced, new raditor, replaced thermostate, heat gauge still shows it getting hot UNLESS I turn on the heater fan, doesn't matter where temp is set...


Terry, what's happening, is when you turn your heater on, no matter what temp you have it set at, the vehicle allows coolant to pass through your heater core, and the blower motor acts as another cooling device for the anti-freeze. The next steps I would take, is to check your fans. Let the vehicle warm up a bit, and look under the hood and see if they are turning on at all. If they are, next, you may need to flush your entire cooling system. First start with the radiator, and if that does not help, you may need to flush the entire system, which flushes water jackets throughout the engine, AND the radiator at the same time. Now, if you are not seeing bubbles, (check under the radiator cap also), I would doubt it is a crack anywhere. Take the first steps I gave you, and see if this fixes the problem. Hope it helped you out.

Just replaced radiator, but temp. gauge is rising to the red line


preform a pressurized collant flush , take it to a raidior shop to have it done , they will clean and blow out all blockages that might cause your car to over heat. also check to make sure you dont have air pockets in your anit freeze, if you do you need to bleed the system out after you have it flushed , your car should have a blead valve to let out the axcess air ,if not drive it down the road with the cooaint overflow cap off , not the radiator but you need to flush out the system first , add new anti freeze then bleed out all air pockets, hope this helps

The guage for our 2001 Ford F150 begins to rise to hot when we turn on the a/c. It has rising for the past 2 days


Start with the basics such as verify correct coolant level and water pump operation. Check air flow across condenser and radiator. It is easy to fold-over the cooling fins with high pressure at car wash. Observe operation of fan to make sure viscous function properly spins fan blade at high temp. Also verify a good radiator cap. All the basics covered and no problem found you should then look into possibility of restricted radiator core, especially if temps are rising slowly, such as under load or long, hard pull up a hill. Will be more noticeable on hot days. Least likely from the description is thermostat, though don't forget it if necessary.

2004 dodge ram 1500 overheating on the freeway


The 2002- 2007 Dodge Ram 1500 4.7 L. has a single core radiator with flat fins that become easily plugged with scale and other stuff floating around in your motors cooling system. Since these fins are so small about .040 of an inch good luck flushing out any clogged particles by doing a flush. Many of the online part stores have replacement radiators for less than $120.00 (Rock Auto, for example). Replace the radiator with a new unit. Make sure to flush the engine block and heater core before connecting back to new radiator. I completed this job over the past weekend in less than 3.0 hours start to finish. Have less than $220.00 in all hoses, Thermostat, Radiator and new coolant.
