Question about 2000 Chevrolet Venture
Hi if when you filled the coolant back up you trickled the coolant in to prevent an air lock and if you also undone all the air bleed screws that run around the top of the hoses that run around the top of the engine, if you done both of the above and you still have it over heating and not heat in the car then this sounds like bad news.
it sounds like it could be head gasket trouble.
first i would drain all the coolant and refill it very slowly and undo any bleed screws if you have any in any of the top hoses, then when the coolant level is where it should be do bleed screws up if you have them and then start the engine but leave coolant filler cap off turn the heater on hot and turn it on then let the engine reach normal running temp then put the coolant cap on.
then see if it over heats, if it does then you need to have a gasses test done to prove the head gasket is at fault.
you can buy this test yourself from car spares shops and its a bottle that fits over the coolant filler cap and it has a blue liquid inside it then you run the engine and draw the air through this liquid and if the head gasket has gone it will change the color of the liquid.
check oil for signs of white substance this would prove head gasket failure if no signs of this then you need to have the sniff test done before you do any more work to the car as you could be throwing money down the drain.
let me know how you get on or if you need further assistance ok
