    This system is done in one of two ways. vacuum or bleeding the system of air. The last thing you want is a air bubble in the cooling system. vacuum if you own the tools, after it is drained it puts a vacuum on the system and willing tell you if you have a a leak(or it can create a leak) Then you have a bucket of anti freeze there and it vacuums it into the engine(theory is it pulls in just what it needs)

    #2 Drain and fill system while engine is running open bleeder valves to let air out of the system should be about 3 valves. Air in the system can and does cause over heating

How to flush coolant system in 1998 Olds Silhouette


Here's a link to read about your Olds.Here's a kit that has instructions how to flush.You need to drain the system, the drain valve is located on lower driver side of the radiator. When the system is dry, shut the valve and fill the radiator with new coolant. Fill until the coolant runs out the top, fill the overflow tank to cold mark.
Start the engine and let it warm up until the thermosat opens. Standing in front of the vehicle there is a small bleed valve located on the right just above the thermostat open it until the coolant comes out and shut it back off. Located on the left of the engine just above the water pump is another bleed valve, do the same with it. You may have to do this two or three times before you have all the air out of the system.

My 2002 Oldsmobile Silhouette keeps overheating. We replaced the thermostat and flushed the system by adding new antifreeze. The air blows cold from the heater when the car starts to overheat. Once


there can be air pocket somewhere you need to bleed system properly. rais the front let is idle bleed it thru bleeding screw. be sure that bubbles are over.

air pockets prevent coolant travel inside system. so it may not reach to radiator, or cabin heater or both.

My 02 silhouette just started having the same problem and I was told it was the head gasket. I was told mini vans with the 3.4 engine have this problem after a certain amount of miles. My brother has had this happen in 2 different vans with same engine. Hope this helps.

Why is my 1999 oldsmobile still overheating after changing the thermostat and flushing out the radiator?


Could be a bad intake manifold or head gasket. These are prone to that problem. If you are lucky you may only have an air bubble in your system. Fill the system with the bleeder screw open until antifreeze comes out and then seal it. Make sure you have enough antifreeze in the radiator itself, dont depend on the overflow bottle.

My 2001 oldsmobile silhouette keeps over heating. i have replaced the water pump and the thermostat. it keeps getting air in the water lines but i can't find a leak. it won't cycle water through the heater...


Hi!

I have and 98 Intrepid 3800 motor, and had same problem.

I tried a few things, but what finally worked was when I took the car for a complete cooling system flush, they opened the radiator and cleaned every single passage line, flushed motor and heater core,

It cost me about $100 but I havent had a problem since. I recommend you do the same.

There is a screw on the thermostat housing that is used to purge the air out of the cooling system. On your owner's manual are detailed instruccions of this procedure.
