Sounds like a blown gasket. The pressure at combustion chamber varies from 75 in idle up to 150 in higher RPM. If the cylinder head gasket is blown, then gases are blown into the cooling system, increasing the pressure, the radiator cap pressure relief valve is open and coolant is discharged in the coolant bottle. In such cases it is common for the coolant bottle to boil. You can observe gases discharging in the bottle, mixed with coolant, from the cooling system. These are symptoms of a blown cylinder head gasket.
To find it out you have to perform cylinder compression test on your car. Start with a normal ("static") compression test. If you will find low or zero pressure in one cylinder this might be a bad ring, valve or cylinder head gasket

LOW COOLANT LIGHT


If your coolant level is full the low coolant switch is probably faulty they are normaly just a float & the float might be stuck. & Coolant should be used all year round as it is not just anti freeze but is (Anti freeze, Anti boil, & acidity, alkalinity regulator.) It changes the freezing/boiling point (water freeze at o degrees centegrade & boil at 100 degrees but with glycol it changes this depending on what % glycol there is in the system. The acid/alkaline regulator is corosion inhibitor to prevent parts being eaten from the inside out (radiators, heater cores, welsh plugs etc..)

Have changed the water pump, thermostat, radiator, radiator cap, all hoses. 2001 chevy venture, still running hot? How long does it take to bleed the cooling system?


If the system fills via an expansion tank, I would recommend removing the top hose from the radiator and filling the system by pouring the coolant in through the hose until it begins to flow out of the upper radiator port. Reconnect the hose and then fill the expansion tank. That should take care of it.

Cant stop a 201venture van from over heating the heater works the van dont run hot but wen the heater dont heat the motor runs hot


When your not feeling heat coming from the heater it usually means that the coolant level is too low in the radiator. It sounds like you have a coolant leak somewhere which is causing your overheating problem. Fill your radiator and let the engine run for about a half hour with the radiator cap on tight. Then turn off the engine and check for any leaks under the van. If you don't see any leaks under the van then see if the carpeting is wet on the passenger side of the vehicle. If the carpet is wet and it smells like anti-freeze you have a heater core that is leaking. I hope this helps you. :)

How do i add anti freeze when low on 2000 chevy venture


Open the radiator cap, by pushing down and twisting counter clockwise. and pour it in. If no radiator cap, line will fill from the overflow reservoir.
Either way, wait until the engine is cool, as radiators produce extreme heat and pressure, which will vent as you open the cap.

Have a 2000 chevy venture mini van when idleing for a while will not over heat when just start it and drive will over heat replaced everything exept radiator for the cooling system and ran a pressure check...


check the lower rad hose , it may be collapsing, it should have a spring inside to prevent that problem, overheating only when the engine is run at higher rpms

Overheating


If you are adding anti-freeze every time this happens, you are still loosing coolant some were. I assume there are no puddles on the garage floor or where you park the van? Check the oil dipstick and make sure the oil is not a "milky"color. Check the passenger side carpet for wetness, you may have to pull it back.
If all of that is OK, you are still burning the coolant by way of the intake gasket or head gasket.
Good luck, let me know.
Regards,
