Overheating car


maybe you have a blown head gasket your leaking head gasket when ur car is cold open your radiator cap see if the coolant in it try to tap up coolant until the neck of your radiator then start your engine and observe the radiator neck if the collant puks it out if your coolant is pukking out meaning you have a leak or blown head gasket and thats the cuz of your overheating

Coolant bubbling bact through resovoir.Replaced thermostat and water pump and flushed system. Still idels at 215 degrees and runs at 221. Top hose is hot and bottom hose os hot on engine side and cool on...


I doubt the radiator is plugged up. The hose should be cooler coming out of the radiator than going in (top).
If the overflow tank is bubbling it could be from the hot coolant, or you could have a head gasket leak and allowing compression - exhaust into the cooling system.

Low coolant level in 2003 yukon after radiator flush


When coolant gets drained and refilled air bubbles are often trapped inside the cooling system. If you imagine pouring a soft drink and you see all the little bubbles sticking to the sides of your glass, you'll get the idea. After driving those bubbles eventually "burp" their way up to the top, and consequently the coolant level drops. Top it up one more time and my guess is you'll be good to go.

CAR CONTINUES TOO RUN HOT AFTER REPLACING WATER PUMP, THERMOSTAT, AND RADIATOR, BEEN TOLD IT MAY HAVE AIR BLOCKAGE, DON'T THINK IT HAS A CRACKED HEAD OR BLOCK, DOES NOT LEAK WATER, NO WATER IN OIL, OR...


Try this.

With the engine cool remove the radiator cap. Now start the engine and let it warm up to the point where the thermostat opens. You can usually tell when this happens by checking the temperature of the upper radiator hose, and the coolant level in the radiator. It will start getting a lot hotter quickly when it does and the coolant level should drop.

While the engine is warming up, watch the coolant in the radiator for air bubbles. Fill up the radiator as needed while continuing to watch the coolant level. Having the radiator cap off while doing this allows the trapped air to escape more easily. If you do have a large air blockage then when the thermostat opens you should see a large drop in the coolant level. You want to keep the Radiator full. Once the air bubbles seem to have stopped you can replace the radiator cap.

You may have to repeat the process a couple times if there is a large amount of air trapped in multiple pockets.

A cracked head or block you can usually diagnose as there will be a lot of small bubbles coming out constantly while the engine is warming up, and even more bubbles if you rev the engine higher as the compressed air/fuel will be forced into the cooling system.

My subaru 1996 250t non turbo over heats after running for awhile, radiator emptys out, dosent seem to have any holes/leaks but there is water on the underside of hood surgesting it coming out of radiator...


refill rad start car wait 3- 5 min now look in rad since you never put rad cap on

if low fill
if not low check temp gage if high them it's time for thermostat if reaching temp slowely make sure rad fan coming on
no fan ? check fuses and releys both good then it's a sensor and will likely require a quick trip to see boby da mechanic

When the car is completely cool,check the electric fan(s) for smooth rotation.

Clean/check/change the thermo sensor,contact and wire.

===

Excavate air pocket in coolant system / check for head gasket leak

This test will kill two birds with one stone.

===

MAKE SURE THE COOLANT SYSTEM and ENGINE IS COLD!

RAN THIS TEST IN A WELL VENTILATED AREA ONLY!

You will spill some coolant during this air pocket purge test.......BE KIND TO THE ENVIRONMENT and ANIMAL please clean up after the test!

===

Put the front end on a pair of ramp or park your car on a VERY STEEP HILL (radiator facing top of the hill) .

Top of the coolant reserve tank

Let it ran for 10-15 minutes.

Monitor for air pockets escaping from coolant reserve tank.

Small amount of bubbles is OK at 1-5 minute mark

After the thermostat open up (after 195 F warm up) at
5-12 minute mark or after high idle you should see less bubbles.

If you do not see any in rush of bubbles then your thermostat may be partially stuck or rusted badly inside the thermostat hosing.

Give the thermostat host few gentle taps.

If you see larger bubbles surfacing after 15 minutes then should do a hydrocarbon (HC) dye test to test for potential head gasket leak.

Let engine cold down and top off coolant reserve tank.

Start monitor for coolant lost

===

A coolant flush is require every 2 years or 24,000 miles.

I recommend the thermostat that has a relief pop-let to reduce the change of burst radiator and coolant hoses.

Make sure you get a new thermostat gasket,black RTV and fresh coolant for the job.

Overheating 94 tercel


Overheating can be the result of several things including: No coolant, stuck thermostat, cracked head, blown head gasket, bad water pump, cracked radiator side tanks, and poin holes in one or more hoses.

Start with the easiest things first. Check coolant level, if it's low you need to find out why. If it's at a normal level you know the coolant is not circulating through the motor. To test this run the car to temperature then feel the upper radiator hose, it should be hot and firm to the touch. Next feel the lower radiator hose it to should be hot and firm to the touch. If it's not the coolant isn't flowing through the motor which is the result of a stuck thermostat.

If the thermostat checks out ok crawl under the car and check all the connections between hoses/motor/radiator. Look at the side tanks of the radiator. If there's a carack in one they will only leak while the system is under pressure. Next check to make sure the water pump is circulating the coolant and not leaking. A siezed water pump will usually stop the pulley from turning resulting in a broken belt.

NExt look around the area of the head gaskets for signs of leakage, again this will only leak while the system is under pressure. Check the oil, if it looks milky there's coolant in it which is a sure sign of a gasket failure or cracked head. Good luck.

Temperature gauge indicates overheating, but engine not overheating, coolant being push into reservoir.


hi my name is brad i see you are haveing a problem and i think i might know the problem. if you have done all of that to your car and it still over heating you might have a blown head gasket one way to check is to pull your thermostat out and fill your coolant leaving the cap off then start you car let it rrun a few minutes and if you see bubbles the radiator its the head gasket even though you wont have coolant in your oil or out the tail pipe. if you check that and ther is no bubbles i have one other spot for you to check ( dont know if you have the 1.5 or 1.6 sohc ) but if you have the 1.6 sohc with the mpfi you should check on the throttle body at the idle air control valve(IAC) you will see two small line`s that have coolant some times on hondas with high millage the line will fill with crud and that can cause a problem.. if you have any other honda needs please let me know

Temperature gage has fluctuates between 100 and 260, the water is full and fan seems to be working ok, and all belts seems to be ok.


You need to verify that the gage is accurate, if it is then the cause is the thermostat, but check the gage first, a repair shop can do this or you can feel the air coming off the radiator fan, if it is really hot changing to cool rapidly then the T-Stat is sticking open.
