Most are difficult to get to and so many don't work correctly that it it's almost silly to even use it. Far easier is to simply remove lower hose from radiator. It works better and faster. Just be careful though...Don't do hot or you may get an unwanted scalding bath!!

Where is the 1996 Oldsmobile cutlass supreme petcock located?


Well the only petcock that comes to mind is the radiator drain petcock. It would be located in the bottom of the radiator plastic tank, at either the right or left end on the engine side. Many times the tabs that you use to turn it with are broken off, making it harder to see where it is. If you are going to do a coolant flush, just disconnect the lower radiator hose to drain the coolant; it is faster!
If this is what you are doing there is a vent screw in the top of the thermostat housing to let out air when filling the system. VERY IMPORTANT TO DO. I hope that this answers your question.

How to drain radiator coolant


Radiators usually have a valve/petcock located on the engine side of the radiator down at the bottom. Valve turns like a bolt and antifreeze coolant will drain out into your drainpan. Use care as coolant is poison and needs to be disposed of properly. After radiator has drained, retighten petcock and fill to the appropriate level.

My Petcock /drain plug for my Oldsmobile 1995 88 royal broke off while trying to tighten it how can I fix it without buying a new Radiater ?


So if it is tight and it does not leak, leave it. Just remember you will have to remove the Radiator next time you flush it. It is a 1995, so unless it is a keepsake or show piece, then leave it.

The petcock is usually metal at that year unless it was replace.

Locate the radiator's drain petcock on the far right, bottom corner of the radiator. The petcock on the radiator should be either black or red. It will be flat on both sides and resemble the wind-up dial on a music box.

You can get these at the parts store. The one at this link should fit: http://www.autozone.com/autozone/parts/Motormite-Radiator-Drain-Plug/1987-Oldsmobile-88/_/N-iiruxZ91sqv?counter=0&itemIdentifier=98889_0_2826_

I know it's not the kind you had, but it will work. All you really need is a plug. You can even forget about the petcock (lots of cars don't have them anymore) and just remove the lower radiator hose to drain the system.

Thanks for using FixYa.

I want to drain or flush coolant from 2000 intrique but I can not locate the screw. how should I do it?


Some models do NOT have a drain petcock like the old cars did. If that is the case, the easiest way to drain the radiator is to loosen and remove the lower radiator hose from the radiator. Once it is drained, put it back in place, tighten the hose clamp and refill...
Good Luck

How do you drain the radator?


You will need to remove the radiator cap. Then you need to locate the petcock (drain plug) on the bottom of the radiator. Remove the petcock by carefully loosening it. You may need to use a pair of pliers but be careful not to break the petcock. When you reinstall the petcock make sure not to over tighten it, it should be snug but not tight.

Where is the drain plug for coolant system on 1999 Plymouth Breeze 2.4 DOHC. Or do I just disconnect hose at bottom radiator. All I want to flush the system and replace coolant.


on one side of the radiator near the bottom is a petcock. open the petcock to drain. Take the radiator cap off to do this to allow it to vent so it will drain out.
If you cant find it, remove the bottom hose off the radiator. This is messy but effective.

I am unable to locate the radiator drain plug for the 1998 olds 88


The drain petcock is on the driver side of the radiator at the bottom in the side of the plastic. It is slightly recessed in the plastic. Will need pliers to loosen counterclockwise.
