SOURCE: just installed rebuilt engine for 2001 chevy 1500

yes it may be, but did you check the radiator for blockage? inside and out side, check to see if there is dirt on the fins. also check the cooling fan operation.
top hose get hot so that meant the thermostat is working ( it's opening ) try to bleed the cooling system again

Where do you add the coolant in a chevy Malibu maxi 2004?


You add at the coolant surge tank. The surge tank is located at the rear of the engine compartment, the tank has a radiator style cap on it. Never open hot!

Where do I add coolent to a pacifica?


Under the hood you will find a plastic coolant surge tank, it has a regular radiator cap on it, coolant is added there, the tank is pressurized and coolant can cause severe burns, so never open on with hot engine use 50/50 mix of coolant or premixed. The coolant surge tank is located behind the battery next to the strut tower at the firewall. There is a picture on page 320 0f the owners manual.

I realise my engine lights comes on high coolant temp and when i opened the hood ,the coolant was dripping from the container you fill it at,can you please tell me possible problems


Depending on your system (either sealled radiator without a cap and a pressurized surge tank or standard radiator with cap and an overflow tank) either the radiator/surge tank cap is not holding pressure and the coolant is unable to pressurized and boils at a lower temp, boiling off until you coolant level is so low the engine overheats. More than likely it is either the thermostat or water pump. Commonly it is the thermostat

COOLANT LEAKS ONLY WHEN CAR IS BEING DRIVEN. NO LEAKAGE ON GARAGE FLOOR. INTERMITTANT CONDITION. 2001 CADILLAC DEVILLE


From the way you describe it, It is likely the pressure cap on the surge tank (expansion/overflow coolant tank).
It is probably worn and no longer able to hold the pressure.
The cap is an inexpensive replacement so do this first.

Can a worn out coolant cap cause overheating


There is no radiator cap on the Northstar engine.
The only cap is on the surge tank (or expansion tank) and is pressurized.

So the answer is Yes, a faulty surge tank cap will result in the loss of coolant and therefore lead to overheating.

The most common overheating problem with the Northstar engine is a blocked purge line(small hose).The purge line is designed to purge air out of the cooling system.
There is a small diameter hose coming from near the top of the coolant tank (not the cap) ,this is the purge line.
With the engine idling,pull the purge line from the tank,if there is no coolant flow from this small hose,it is blocked and this will cause overheating.
If the hose is clear, check for blockage at the nipple on the tank.Or trace the hose back until you find the blockage.
The hose goes in to the engine to a crossover and comes out the other side close to the thermostat housing,the blockage may be there.

Coolant


Open the surge tank cap and pour the coolant in. At the top of the therm. housing, you'll see a bleeder valve. Start and run the car, make sure the surge tank is full, and crack the bleeder valve until you see a steady stream of coolant come out.
