What would continue to cause overheating water in overflow tank boils after a five minute drive in an 82 Buick after replacing the thermostat and fan clutch?
If the engine has been overheating there is a real possibility that a head has warped, causing head gasket failure. If it's boiling over that soon after starting the engine, you should be supicious of a head gasket. You should be able to check the coolant for carbon monoxide as a test for head gasket failure. Test kits are generally available at auto parts retailers.
The most common cause of overheating is a thermostat stuck in the closed position. However, other causes are: faulty water pump, clogged radiator, clogged hose(s), coolant leak or a broken drive belt. I had a 1987 legend with around 160K that was overheating. Antifreeze would boil out of the overflow. I changed my radiator and it fixed the problem.
Several possibilities - from easiest to most expensive: Faulty or inoperable radiator cooling fan - causing overheating. Faulty thermostat - causing overheating. Water pump failure - causing overheating. Blown head gasket - allowing exhaust gasses to escape into the cooling system and expelling the coolant.
When the check gages light comes on the temp meter is in the hot zone and the overflow tank is leaking out anti-freeze is that an indication of low coolant in the radiator of my '97 grand Cherokee?
Make sure the radiator is full of water, don't just check the overflow tank, but do make sure the car is cold before removing the radiator cap. Also the thermostat could be frozen closed or you could have a failed water pump. Try replacing the thermostat and flushing the cooling system first. Don't forget to buy a thermostat gasket when purchasing the thermostat.
THATS WHAT THE OVERFLOW/EXPANSION PACK IS FOR. WHEN ANTIFREEZE/COOLANT BEGIN TO BOIL IT EXPANDS AND IT NEEDS A PLACE TO GO. THERE FOR IT GOES IN TO THE OVERFLOW/EXPANSION PACK. THIS PREVENTS DAMAGE TO THE ENGINE/RADIATOR AND OVERHEATING. THERE IS ALSO THE POSIBILITY OF A MALFUNCTIONING SENDING UNIT/GAUGE.
96 grand am se 3.1 and it keeps overheating when idle or driving slow but it stays cool when im in constant motion or in winter got to keep heat on during summer .i changed thermostat and flushed rad.?
i had the same problem in my 96 grand-am i actually replaced the radiator, coolant overflow tank, and thermostat before it stopped. Check your coolant overflow tank and check for cracks and whatknot. If nothing else check the fan and make sure all belts are in proper motion and stuff. hope i was some help
Either: 1) Thermostat is bad or 2) Radiator is clogged or 3) if your losing fluid or hearing a noise, check your water pump. If your not losing fluid or hearing a noise, the service the radiator by having it flushed. If this doesn't solve your problem, then change the thermostat. If your still having the problem then your radiator may need further service or even replacing. I'm having the same issue right now. I'm…
likely possibilities are the following. Low or bad coolant , water pump, thermostat needs changing, clogged radiator or lines, coolant temperature sensor or radiator fans not coming on, head gasket Also check the radiator caps on the hose and the overflow container. That was my problem. One or both may have to be replaced.
The overflow bottle may overflow if: 1. The car is overheating - this means after the coolant in the radiator gets heated up and expands it flows to the reserve bottle but the radiator doesn't cool down to suck back the coolant from the overflow bottle, but just keeps on sending coolant to the bottle. 2. You may have put excess coolant in the bottle - hence heated coolant from the radiator didn't get enough…
1999 mercury cougar overheating new thermostat.. not leaking antifreeze only leaks through the overflow when car stops but doesnt over heat... antifreeze resvuior always seems to be under pressure?
The heater core has no overflow hose. Cooling system is a closed loop system and the only overflow hose is the one going from the radiator cap to the reservoir. A thermostat that is stuck closed will cause the engine to overheat. Drain and flush the radiator, replace the thermostat, install a 50/50 mix of antifreeze and distilled water, bleed air from the system. You may also need to replace the radiator cap. Be sure…
1995 Sidekick coolant leak there are two hoses that come out of the reservoir one connects to the radiator the other is not connected to anything what is this where does it go and cost to fix?
On a 1992 ford f250 why would the coolant back up into the overflow container and stay in the radiator?
if the coolant backs up and does not circulate, either the water pump and/or the thermostat need replacing i would check the pump first as the thermostat does not prevent circulation, just doesnt allow proper operating temp the water pump on powerstroke is an easy replacement job for a handyman but remember the bolt sizes are metric. i think they are 8 mill bolts
If your 1997 Subaru Legacy is the same as My RS-B Twin Turbo?, the Radiator and Overflow bottle have to come out and the Thermostat is at the front of the Engine, down the bottom-just to the right of centre, (Thermostat is inside the bottom radiator hose), - My Thermostat just twisted/pulled out, let all old coolant flush out-put New Thermostat in its place, Radiator and Overflow bottle were put back in and radiator topped…
What would cause antifreeze to boil in overflow tank in 2003 Chevy Venture happened twice now and neither time has the temperature gone up to the red area and engine overheating light hasn't come on?
Replace the radiator cap with the proper OEM cap. Be sure and use the exact same pressure cap. If this happens again after replacing the cap, then you need to do a complete service of the cooling system. Drain, flush, replace thermostat, refill with a 50/50 mix of the proper coolant and distilled water, and bleed air from the system. Also inspect cooling fan and water pump for proper operation.
On the 2002 model, it is on the left side (passenger) of the motor. It is the opposite of what we normally expect. The lower radiator hose is what attaches to the thermostat housing, along with the heater hose and overflow tank hose. I ended up buying the thermostat with housing for $27. No one would sell the thermostat by itself.
