There is a valve at the bottom side of the radiator, but that is for draining the radiator. So you are right, just add what you can with the engine off, let it all settle, and than stand clear, but fire it up, and slowly add more as needed, when you are done, turn it off, leave the cap off, let it set for a minute, and if the level goes down, add some more and restart it. You want to be sure there is no remaining air in the system because air pockets will cause parts of your engine to overheat which can cause other issues. When you are done, put the cap back on, go drive around till the engine is hot, let the vehicle sit for 2-3 hours, when you come back to it, carefully, with a rag covering your hand, slowly turn the cap in case it is still hot. (I know you may know this but I'm just covering my a$$ in case you get burned :) please be safe). Anyways recheck the level, and if its good, and you see no leak coming from the hose than you are good.

No just fill it up from the radiator cap and let the engine run until the thermostat opens(signified by sudden "loss" of coolant) or 20 mins

IF YOUR HEATER CORE WAS LEAKING ANTIFREEZE INSIDE YOUR CAR, IT WILL STOP LEAKING ONCE YOU DISCONECT THE 2 HOSES FROM OUTSIDE ENGINE COMPARTMENT, THERE WILL BE NO MORE ANTIFREEZE GOING INTO YOUR HEATER CORE SINCE YOU WILL BYPASS THE HEATER CORE.

ONCE YOU CONNECT BOTH HOSES TOGETHER, THE ANTIFREEZE WILL CIRCULATE BACK TO THE FRONT RADIATOR AND NO OVER HEATING AND NO LEAKING INSIDE YOUR CAR MO MORE. YOUR CAR WILL DRIVE FINE, YOUR AC AND FAN WILL WORK THE SAME...SO LONG THAT WAS THE ONLY PROBLEM.

Pontiac sunfire overheating


hello! I had the same problem with my 2000 Pontiac Sunfire... there might be one of these 2 problems with it.... maybe the Heater Core is jammed and the coolant dosen't flow thru the engine to cool it off, or the water pump is defective.... does the heating works or not? if yes, the water pump is defect, if not, the heater core is jammed, try a ''radiator hose cleaner'' (sold in Napa's or Carquest..) it will act as a kind of ''decloaker''.. if works, good! 15$ solution... if not, replace Heater Core... ~150$

Hello,

To replace the core of your GMC 2001 Jimmy, You will be needing these instruments, Repair manual, Socket set, Screwdrivers, once You have them together, please follow the steps below:
  1. Lift up your car's hood and locate the heater core. If you are not sure where the core is located, an auto parts store employee or a repair manual can help.
  2. Remove the screws or bolts that hold the heater core in place. You may need to remove other parts of the car before being able to access the heater core.
  3. Disconnect the intake and outtake hoses from the heater core. You may need a special tool to remove the couplings that connect the hoses to the heater core (refer to your car model's repair manual.)
  4. Remove the heater core. Be careful not to tip the core over, as coolant will leak out.
  5. Reconnect the upstream and downstream hoses on the new heater core in the same matter that they were attached to the faulty core. Leaks can occur if the hoses are not connected properly.

if your rubber hoses are cracked and leaking then replace the hoses with proper size and length.

Hose going in to the heater leakes right at the firewall. I replaced the hose and it still leakes.What could be wrong? can i get too it from the inside?


Your hose should connect to one of the nipples for the heater core. Some times these are brass, so be careful. Look it over for corrosion build up, or even a crack. The heater core is similar to a small radiator, and is almost always very tough to get at.

99 jeep cherokee problem w/ heat I replaced the blower motor, water pump,radiator, thermostat and flushed the coolent system. Still getting little heat. I'm thinking heater core or head gasket... Is there...


It sounds like the heater coil needs flushing out or replacing or the heater valve. Look on the engine firewall and make sure the heater valve is opening. If not open it manually and check the heat level. If that produced heat check the condition of the heater vale cable (or vaccum hose).

Leaking coolant water


This L shaped hose is a drainage for the heater core compartment. Once we removed the panel to the heater core it was obvious the heater core was leaking into this compartment. We changed the heater core out and the problem has been solved :)
