It is a improper connection is somewhere inside..
when the cap is opened the liquid does overflow at once ...there is not problem in the engine..

check the connections

Why is the coolant overflowing when the temp guage gets half way?


well the tank must never be full, when engine is cold
was it? (read operators guide to see methods)
water expands hot, and the tank captures this expansion
that is normal.
what does "until its all gone", mean, what is IT?
there are lots of tests.
the first one, is,
IS the engine overheating,?
try a new rad cap, they are dirt cheap.
and, is the oil or carbon in the RAD neck, cap off , cold engine>?
is there water in the engine oil, milky dip stick end?
same with A/T trans? milk, or pink/red ATF.
is there steam going out the tip of the exhaust pipe on a fully hot engine>? yes/no?
is air and water exploding in to the side expansion tank.?

cold engine
remove rad cap'
fill rad with 50% AF.
new cap back on.
put 50% AF 1/2 way up in to expansion tank(its marked clearly)
start engine , does it overflow now>?

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.

My 2000 Toyota Echo has the red engine temp light flashing. I checked the coolant container about an hour after I parked in the shade of my house. (95 degrees here today and I was driving on the highway...


a flashing check engine light (CEL) is a warning to stop driving-one that is on steady (not blinking) means something is wrong, but blinking is BAD-make sure it is completely cooled down, and fill the overflow/surge tank, start it up (use 50/50 antifreeze) and let it idle until the engine temp is all the way up-this can take 10-15 minutes, make sure the heater is on high temp setting and the fan is on-look at the temp gauge if it has one to see if it looks normal. If all looks good, fill the tank to the FULL mark (or a hair above it) and put the tank cap on tight. Drive the car for about 10 minutes, and pay attention to the temp gauge-if it looks good, and the engine is alright, the CEL probably with either not light or will go off by itself.

It is possible you did damage driving it with a flashing CEL, however-if so look for leaks, smoke out of the exhaust, poor running/performance, or more ominous signs of trouble like air bubbles in the overflow tank, oil in the antifreeze of antifreeze in the oil-aluminum engines do NOT tolerate overheating, if you ever see a high temp gauge and/or a flashing CEL-STOP and get it checked out, you will save yourself a lot of money being prudent.

Was driving my 1999 chevy venture this morning after 12 miles had no heat & temp gauge pegged in the red. then went down & came right back up. Stopped & turned it off for 20 minutes or so. ...


You are describing a slow coolant leak and the resultant no heat and blockoverheating symptoms. The no heat is because there is insufficient coolant to cycle through the heater core, and the chuggin you describe is the engine indicating serious overheating.
With engine cold, you must add water--not anti-freeze--to the radiator itself, until it reaches the top of the radiator, then start the engine. If you do not have a radiator cap in addition to the overflow bottle (some vehicles don't), you must still add water to the radiator, even if you have to bypass the overflow bottle hose to do it. Add water until no more will go into the radiator. Start engine, let idle until operating temperature is reached. Thermostat should open and a good bit of the water will "sink" into the depth of the radiator. If you have no radiator cap, observe the temperature guage. When it reaches normal operating temp, when the thermostat opens, the temp will drop briefly at first, and you will notice warm air from the heater/defroster.
Once engine is warm and known to be full of water, seal radiator cap and/or system, and let idle for 30 minutes. Use this time to locate the "mystery leak." They can be very hard to find, and some won't leak until after the engine is turned off. During this idle period, observe the vehicle exhaust from the tailpipe as well as looking for actual water leaks: sometimes a bad head gasket can be diagnosed this way; if the exhaust is white and thick like steam, and smells like anit-freeze, you have a more serious problem. It is possible that after the repeated overheating cycles you have endured you may now have both a "mystery leak" and a blown head gasket.
Once leak is located, your next step is to let engine cool completely, drain the water, fix the leak, and then and only then add new antifreeze of the proper rating and ratio recommended by Chevy for your vehicle.
Anytime you drain a cooling system and refill it, it is necessary to check the overflow bottle at least 3 times in the first week after repair to ensure that you have the proper coolant level, and have not either missed another leak or not correctly repaired one. You MUST check it before you drive the vehicle the second time after the first repair attempt because it is normal to need to add more coolant than you added initially after the repair because of air trapped in the cooling system that will only be expelled after the first start/stop heating cycle. If after 1 week of daily normal driving you have only added a little more coolant once, and there are no more problems, you can be very comfortable that you have fixed your car.

My coolant expansion tank is overflowing after 20 minutes running


There could be a couple of reasons for this,

1. The thermostat could be stuck closed creating more pressure than normal. Your temp guage would show a higher temperature or you have another blockage in the system.
2. The expansion tank is too full.
3. The cylinder head may be leaking. If you fill the system run the engine to normal temperature with the radiator cap off, look for quite large bubbles coming out of the filler cap. If the head is badly leaking, they can be like a volcano. The temp will rise quickly from cold and the engine will overheat in a short distance.
It does seem odd that it would only spill over after 20 mins. Suspect that the expansion is over full first if your temp is normal. Let it run until it stops and see where the level is when the engine is cold.
