Removing the radiator is a pain. Worse it trying to replace it. I bought three of them, sent two back, and saw that the third was almost right. The one that I kept I brought to a radiator shop and the core was a close enough match that they were able to use it to fix the old radiator and I put it back in the car.
If you want to flush it, just use a flush machine.
If you want to drain and fill, it's like any other car.
With any 60 degree GM V6 look for as many as two bleeder valves, and consider using a vacuum fill tool to prevent damaged cylinder heads.
If you want to drain and fill a 2.5L I4 engine, filling is special:
Do not remove the radiator cap. This it important.
1)Remove the thermostat housing cap. Remove the thermostat, then add coolant though the opening.
2)Put the cap on, then start the engine and let it idle for about 15 seconds and shut it off.
3)Remove the thermostat housing cap, top off the antifreeze, then install a new thermostat. Put the cap on.
4) Check and correct fluid level in the overflow bottle.

If it's a 2.5l... Open the hood and look straight down behind the radiator.

Dont try to flush the radiator... when you drain it and try to flush it, what you will be doing is breaking up all the old gunk in the radiator, by breaking it up, you will have no clue if its completely clean or not, so if the gunk is still floating around, it could go threw the engine and clog up the engine, making it over heat and really mess things up... now if you want to just change the coolant, the drain plugs are on the botton corners of the radiator, theres 1 or 2 drain plugs... i forgot how many, but it would be alot safer to change coolant, then to try to flush the radiator.
It is easiest to remove the thermostat and drain the radiator by removing the lower hose. Dispose of the coolant properly. reinstall the lower hose and run water from the garden hose through the engine with it idleing until it runs clear. Then remove the lower hose to drain the radiator and reinstall the thermostat with the spring toward the engine. Then fill the radiator with coolant and start the engine up and top off the radiator after the thermostat opens. You should end up with about a 50/50 mixture of coolant and water. Good Luck Joe
The radiator is located in the front of the car, where it is located in most cars. There are coolant pipes running beneath the car, under protective covers, that feed coolant to and from the radiator. There are three drain plugs on the car, and it is a complicated system to flush.
The radiator support on a 1991 Acura Integra is held on with several bolts. Use the appropriate sized socket and loosen all the bolts. Pull off the support.

Hey Ryan==Simply remove the neg battery cable then the ser belt then the wiring on the alternator then the bolts that hold it on. GoodluckJoe
Follow the upper radiator hose from the radiator to the top of the engine. There will be 2 bolts once you have drained the radiator you can remove these bolts that hold the waterneck housing down lift it up, and there will be the thermostat.

To replace the thermostat on a 91 Cavalier you need to drain the radiator. Remove the top radiator hose and water inlet. Remove the thermostat from under the inlet. Install the new thermostat and reinstall the inlet and hose. Fill the radiator with fresh antifreeze.

Ethylene glycol is biodegradable and is harmless when flushed down the toilet in relatively small amounts. Maybe that's not what you mean: if you want to flush the radiator, I usually open the petcock on the radiator, remove one heater hose from the thermostat housing area and backflush the heater core with a garden hose. This will usually get most of the antifreeze from the block. Allow to drain, close the petcock and refill with about 2 gallons of 100% antifreeze. Top off the rest with water if needed.
Why won't the radiator fan start on my 1991 dodge caravan?
The Oldsmobile Calais, also known as the Cutlass Calais, was produced by General Motors from 1985 to 1991. In 1987, the Quad 4 engine was developed and the 1988 Calais was fitted with it. All?æof the Quad 4 14 engine types of the 2.3 liter version are interchangeable on the 1988 Calais.
1. Drain the cooling system. 2. Remove the engine undercover (skid plate). 3. Disconnect the reservoir hose and remove the reservoir tank. 4. Disconnect the upper and lower radiator hose. 5. Remove the fan shroud. 6. Disconnect the oil cooler lines (automatic transmission). Plug the lines immidiately to prevent oil loss. 7. Remove the nuts and bolts holding the radiator. 8. Carefully remove the radiator..... Note: Installation in reverse.
Bottom of radiator
You do not have one. Disconect the lower radiator hose. (after cold)
at the bottom of the radiator on the driver's side.
You can find the 1991 Buick Skylark radiator drain plug on the bottom of the radiator. The radiator drain plug will be in the center of the radiator bottom.
Its a pain. Basically, with car cold, drain system. Remove battery. Remove shroud. Unbolt fans and let them hang lose. Remove hoses. Pull out old radiator. Put new radiator in. Reconnect hoses.(you may have trouble if there's a converter piece on an inlet) Rebolt fans. Replace shroud. Connect overflow bottle. Replace battery. Refill coolant and top off leaked fluids.
The thermostat is located inside the radiator. Remove the radiator cap and pull the thermostat up. Remember to put the replacement thermostat in the same position push the new thermostat down in the radiator. The O-ring gasket will automatically seal.
