if you want to fit a new one you need to locate and remove the old one, most of the cars the little radiator is located in the rear of the heather control, is a medium difficult job to get that done but you don't need a big brain to do it. if you don't want to fit a new one you only need to find 2 hoses in front of the engine compartment { in the lower part of the engine} you see 2 hoses leading to the inside of the vehicle, you must remove the 2 hoses and connect a little piece of pipe to une the 2 hoses. be carefull do not block the hoses, the water need to circulate trougth the hose to the block of the engine.!! if one of the hoses is big enought you can take the short one out and fit the other end of the long one in where's the short one been . is like make an U with the hose. the problem is the heater now doen's have hot air for winter, but you can do that in summer because you never use that in summer. and no more leaks in the passenger floorboard... I hope this may help u. and a hope u understand what im saying is because my English is no very good. cheeeerrrrssss. bye.
AnswerI bought a 92 firebird that also leaked fluid onto the passenger floor board. I had to replace the heater core and that took care of the problem. Just buy a repair manual that will walk you thru the steps and put aside a whole day to get the job done. Now mine is fine. Good luck..on the 3800 V6 its below the throttle body
located on left side of water pump
it should use Dexcool. it will be the orange stuff
A damaged heater core will cause coolant or water to leak onto the passenger floorboard.
On the 3.8 V6 it is below the throttle body on the front of the engine. You do not have to drain the radiator, just remove and replace. Then top off the radiator coolant.
Open the radiator petcock and drain coolant into a container. Dispose of all coolant properly as it is toxic to animals. Close petcock and fill system with water. Run the engine for several minutes with the heat on high. Drain the system again. Several repeats of this procedure will flush the radiator and engine for the Firebird.
yeah you do need a new heater core which is located in the dash board
Low coolant? Bad thermostat? Defective radiator cap? System air bound? Heater core plugged or restricted? Temperature control cable not adjusted properly?
It could be anything, from a cloggedthermostat, faulty radiator cap, or even the coolant you use. Some require orange coolant not green. It could also be that the radiator is dirty inside, or the radiator is being blocked and air cannot hit it.
If that water is engine coolant, the heater core is leaking.
I have a 1998 Pontiac Grand AM GT that coolant sensor went bad. So how do you change it with out breaking the coolant
Adding coolant to a 2003 Pontiac Grand Am is very easy to do. The coolant can be directly added to the radiator. Make sure the engine is not hot before adding the coolant.
