Question about Oldsmobile Silhouette

1 Answer

When I try to remove the cap to add oil in my 1997 silhouette van the cap turns a revolution or two then stop. The cap won't come off until I keep turning, and then the cap and filler neck come off as if it were one piece. Once off I can turn the cap a bit, cw and ccw, but it will not separate. Is that normal? Shouldn't just the cap suppose to come off? Not the whole filler neck.

You are correct, sound like the filler cap is to tight, it happins, grab the filler tube and cap and remove the old cap and replace with a new one, you might have to break the old one to get it off.

How do i put water in my radiator?


you need to replace thermostat and radiator cap.look under hood around engine compartment.look for a radiator cap near radiator,add 50/50 antifreeze and water to coolant system to bring up boiling point.pure water will cause engine run hotter because water evaporate away,remove radiator pour coolant in the radiator until coolant stop dropping in the radiator now some vechicle pour coolant in the coolant overflow jug,pour coolant until coolant level stop dropping and the coolant level stay at cold full mark.start engie let idle few minutes, watch coolant level in radiator if coolant start dropping add more coolant, when coolant level stop dropping put radiator cap back on let engine idle until both top radaitor hose and bottom coolant hose get warm turn off engine wait until it get cool then take a large rag slightly open radiator just a litle at a time to keep from getting scaled.once radiator remove add more coolant if low,put radiator cap back on start the engine let it idle watch the temp gauge if temperature gauge going hot zone stop engine wait until cool then add more coolant,keep doing this until engine stop overheating going into hot zone and coolant level stop dropping,make the coolant overflow jug coolant level stay at full cold mark, dont let jug run empty if so air will get in the coolant system causing engine to overheat.

Need to know if i need to bleed the cooling system, after installing the radiator?


ADD COOLANT IN THE COOLANT OVERFLOW JUG UNTIL COOLANT LEVEL STOP DROPPING AND COOLANT LEVEL STAY AT THE FULL COLD MARK.PLACE COOLANT OVERFLOW JUG CAP BACK ON JUG.CRANK VECHICLE UNTIL ENGINE START WARMING UP. STOP ENGINE WAIT FOR A WHILE UNTIL COOLANT COOL DOWN TO KEEP FROM GETTING SCALDED. USE A LARGE RAG OVER THE OVERFLOW JUG CAP OPEN OVERFLOW JUG CAP A LITTLE AT A TIME REMOVE OVERJUG CAP CHECK COOLANT LEVEL ADD MORE. COOLANT IN THE OVERFLOW JUG.THEN START VECHICLE AGAIN.LET ENGINE IDLE UNTIL TOP RADIATOR GET HOT.THEN THERMOSTAT WILL BE OPEN.WHILE ENGINE IDLING WATCH THE TEMPERATURE GAUGE IN VECHICLE IF TEMPERATURE GAUGE START CLIMBING IN THE HOT ZONE.TURN OFF VECHICLE LET IT SET A WHILE THEN USE LARGE RAG REMOVE OVERFLOW JUG CAP.ADD MORE COOLANT, PLACE CAP BACK ON START VECHICLE AGAIN KEEP DOING THIS PROCEDURE UNTIL TEMPERATURE STOP CLIMBING HOT ZONE.AND WHEN COOLANT LEVEL STOP DROPPING IN THE COOLANT OVERFLOW JUG.AIR IS OUT THE SYSTEM, BUT KEEP COOLANT LEVEL IN THE COOLANT OVERFLOW JUG AT THE FULL COLD MARK.DONT OVERFILL.DONT LET COOLANT OVERFLOW JUG RUN DRY IF SO AIR WILL ENTER COOLANT SYSTEM BECAUSE COOLANT LEVEL WILL BE LOW ENGINE WILL START OVERHEATING.

The radiator was emptied out and i want to add antifreeze and water? there are 2 areas that say antifreeze goes here?


  • One is the radiator and the other is an overflow tank. Sometimes anti freeze will back pressure a bit and need somewhere to go and other times the antifreeze gets low in the radiator. That is the purpose of the radiator.
  • Put the antifreeze in the radiator fist and then add to the reservoir. Pay attention to the cold/hot level fill on the overfill tank.
  • You need to find out where all that antifreeze went to if the radiator was empth. Pull the dipstick and look for a chocolate milk look on the oil. This would be a head gasket or a cracked head.
  • Otherwise keep an eye out for a leak and repair it soon.
  • Hope this helps and thank you for using FixYa.

My temp gauge goes up to the hot but doesn't overheat but blows cold air then the gauge will drop to bout half n then start blowin hot air replaced thermostat n a new rad cap could it be the heat sensor


No, because it blows cold air when it gets hot. There is air in the system or the coolant is low. Intake manifold gaskets are a very common problem on these engines and if left unattended to can cause even bigger problems such as head gaskets if the engine over heats too much. Check the coolant level and if it is low, look for leaks at the water pump, radiator and especially the intake manifold where it meets the head. Also, pull the oil dip stick an/or the oil cap to see if it looks milky. If it does, there is coolant getting into the oil.

On my 98 Oldmobile Cutlass I can do an oil change on my own and it's got a minor oil leak that would be more costly to fix than it is to just add a quart of oil here and there however, the oil cap will...

Lucas stop leak for motors I used it and it works.

Low oil pressure no start


CHECK ENGINE OIL LEVEL ON OIL DIP STICK.OIL LEVEL SHOULD BE ON FULL MARK IF NOT ADD OIL UNTIL YOU GET TO FULL MARK.IF OIL LEVEL OKAY.YOUR LOW OIL PROBLEM CAUSED BY WORN DAMAGED OIL PUMP OR WORN ENGINE CRANKSHAFT BEARINGS.IF OIL HAS NOT BEEN CHANGED A LONG TIME CHANGE OIL AND OIL FILTER NOT GUARANTEE TO FIX PROBLEM.BUT COULD BE MINOR THING.OIL FILTER COULD BE STOPPED UP.WEAKEN OIL FLOW BUT LIKE I SAID PROBLEM COULD BE OIL PUMP OR ENGINE BEARINGS.REMOVE OIL SENDING UNIT SCREW IN A OIL PRESSURE GAUGE.TURN ENGINE OVER SEVERAL REVOLUTIONS TO SEE IF OIL PRESSURE BUILD UP TO 40 LBS. SEE 40 - 60 PSI. 2000 RPM.IF NO OIL PUMP TO WEAK .IF OIL PRESSURE RISES WHEN TURN ENGINE OVER.I HAVE SEEN FAULTY OIL PRESSURE SENDING KEEP ENGINE FROM RUNNING BECAUSE OIL PRESSURE SENDING UNIT WILL DISABLE FUEL PUMP RELAY TO KEEP FROM DAMAGING THE ENGINE.

the completely empty tranny will take between 12 to 14 quarts, i am assuminge you just replace the transmission filter and think that its empty correct... well in that case add four quarts run it at idle an keep checking the dip stick until it shows a reading between the cross hatched lines in some cases it says add and full keep fluid level in the middle.

Lower intake manifold gasket leaking 02 Olds Silhouette


This is basicly a very time consuming job rather than a physically hard one to complete. In order to replace the gasket you must remove the intake plenum,throttle body, and misc. vacuum hoses. The wiring harness connections must also be disconnected. Finally the intake manifold is exposed. The bolts holding the manifold to the block are removed exposing the leaking gasket. After removing the push rods and placing them in the correct order to be replaced the gasket and sealants can be removed. Finally replace everything in reverse order. Be sure to consult a GM manual for correct bolt torch specs. The correct specs for the manifold bolts usually come with the gasket. Make sure to change your oil a few times after this job in case any coolant entered the block. Also,change the thermostat and the oil seal on the distributor half shaft cap while you have everything off. Good Luck
