There is no drain on the radiator, loosen lower hose to empty coolant. Metal pipes are the transmission fluid lines.
Coolant quantity for the 6 cyl is 14 qts, and 15.3 qts for the V8. If you have the extended wheelbase model, the quantity is 15.2 qts and 18 qts respectively.

They do clog up and will not drain. You probably found the drain. Pull the lower radiator hose. If you have access to air and can shoot it up in the hole. This might help you problem.

How do you put radiator in 1999 hyandai accent


1) Drain radiator by removing cap, and bottom radiator drain bung or bottom hose.
2) Remove top hose.
3) Disconnect the radiator fan's wiring and any temperature sensor wiring if fitted.
4) Remove radiator retaining clasps
5) Disconnect radiator bottom hose.
6) If fitted with an auto box, then remove automatic gearbox oil pipes (Underside)(you might wat to clasp these so they don't leak oil everywhere)
7) Remove radiator expansion bottle feed pipe from top of radiator.
8) Ease out the radiator. If the radiator fan is getting stuck or caught up, then drop the radiator back down and remove the fan first after disconnecting from the radiator body.
9) With new and old radiator placed side by side on a soft surface, change across any components from the old radiator, which didn't come with the new one. These may or may not include such things as: cap, fan retaining screws or clips, bottom radiator seating rubbers, rubber fan shrouding, temperature sensor, top and bottom rubber hoses.
10) Rebuild by reversing the above instructions. Apply silicone pipe sealant to top and bottom hose locations. Make sure you clean and/or replace any heavily corroded metal pipes which connect to the radiator. (Now is also a good opportunity to replace the thermostat to be on the safe side)

11) Fill system with a fresh 50/50 water/antifreeze mix, flush out and refill expansion bottle. Just before you refill the system, turn the interior heater setting up to maximum heat, but do not start the vehicle.
12) Top radiator up to max. Gently massage the top radiator hose to help eliminate air from the system.
13) Once filled, start the car. Pay attention to the temperature. Keep topping up the radiator as bubbles come around the system and the coolant level drops. At the point no more bubbles appear, close off the radiator with the cap. Allow the engine to reach normal operating temperature. If the weather is cold you may want to hold the engine at around 2,500 revolutions to help build heat faster. Keep it running until the radiator fan kicks in, then let it idle for a couple of minutes.
14) Stop the engine and let it cool.
15) Once cool, open the radiator cap and top up again if level is low.

16) Road-test the vehicle. After returning check again for any leaks.


Running the car for the first few days after radiator replacement, check the radiator level and expansion bottle level every day for the first two or three days. This level may drop slightly as any trapped air pockets are pushed out while running. Also, it is possible that any small leaks may begin after adding fresh anti-freeze to the system. If you begin loosing fluid over these first few days, then re-inspect your work and run a cooling system pressure test.

What is proper method for flushing the radiator and engine in a 1999 Pontiac Montana?


1: Drain coolant system
2: Purchase coolant flush, making sure you have the proper amount for your size of coolant system
3: Pour coolant flush into your radiator, filling the rest with water
4: On the coolant flush bottle it will tell you how long to run your vehicle
5: Once done running, let cool enough to open radiator cap, and drain system COMPLETELY by first draining out of pep **** on radiator, then taking one side of the hoses off the radiator and draining those
6: Put hoses back on and fill system with coolant. When the fluid gets to the top of the fill port on radiator, start vehicle and let run, allowing air to escape the system, and fill as necessary

Where is the drainedge for the radioter


For a 2001 Buick Regal GS 3.8 Liter, Supercharged engine:

First, let engine cool some. Second, locate small drainage hole at the bottom left/drivers side, of the radiator. From the bottom of this small drain hole, go straight back toward rear of radiator, then up about 1 1/2 to 2 inches up. (Have a drain pan or pail handy, to catch the old antifreeze.) You'll find a dark colored drain nut. Use a larger, correct sized socket ratchet wrench & loosen this fitting a turn or so, counter clockwise. Old antifreeze will begin to come out the bottom drain hole. The more you loosen the fitting, the faster the fluid flow out. I wouldn't remove the drain plug completely, or you'll loose control of the draining flow rate.

I just changed my anti-freeze just last week. I also changed the 2 large radiator hoses & smaller 2' overflow hose at the same time, as long as I was doing the job. They had never been changed before. I also used new hose clamps & a small packet of "radiator hose grease", from Autozone.. I drove the car up onto front car ramps to make it easier. I used safety jack stands for extra care. " You-Tube" shows some, "how to videos", that are helpful.

The old hose clamps are difficult to get to. (You'll need a few tools, some time & patience.) To get to the upper clamp, near the right/passenger side of the of the car, near the battery, I removed the outer serpentine belt & tension pully. I then removed the factory installed spring tension clamp, with the help of an adjustable battery pliers. The bottom of this hose wasn't too bad to get to. On the left/drivers side of car, remove black air intake box to access upper clamp. Remove the black metal brace bar, the will allow access to the air intake black box.

I also changed the small overflow 2 foot long hose & 2 clamps, that goes from radiator cap area, back to the overflow white plastic tank, close to passenger firewall. I removed the overflow tank to clean it out as well. I drained the fluid & changed the 3 hoses & clamps. I then placed all removed parts back where they belong, including white plastic overflow tank, tension pully & outer serpentine belt, air intake black box & metal diagonal brace, contacting air intake box. I flushed the system with some Prestone Radiator Cleaner & clean water. Start car & get up to temp., then run for about 10 minutes. Let cool, then drain again. I flushed my car at least 2-3 times after this, until the drain water ran clear.

The best price on a 5 year/150,000 mile anti freeze, came from Wal-Mart. I then mixed about 50/50 with Distilled water, as suggested on the bottle. All went well & no leaks! I took my time and did a thorough job. Good luck!

How tjo do a radiator flush in a 1999 Grand AM SE


The best way to flush it is with a flush machine.But,if you don't have one then follow these steps. 1. Put a catch pan underneath,where you will be draining the fluid. 2. loosen the petcock at the bottom of the radiator. If you don't have access to it,then remove the lower radiator hose and run the car for a minute to let the rest of the fluid drain. 3. With the fluid drained out,tighten up the petcock or the hose and put a bottle of radiator flush chemical in it.Prestone makes this and you can get it at a parts store. 4. Add the contents of the bottle and fill the rest up with water. 5. Run vehicle for 10 minutes and drain. 6. Loosen the 2 pressure relief valves.1 is located on the coolant tube running from the passenger side to the drivers side.The other one is located on the thermostat tube.They are both copper in color and you will need a 10 mm wrench and a 6 mm or 7 mm wrench to loosen them up. 7. Add the recommended fluid,usually Dex-Cool for that year,until it comes out of the relief valves.Tighten the valves back up (be careful,they break easily) and run the vehicle till at proper temperature. If it seems to get a little on the hot side, Loosen the relief valve until the air bubbles are gone and top off the fluid. Please remember to dispose of the fluid properly in accordance with the law.

1995 Subaru Legacy Wagon Radiator


Hi sir, if you want to do a proper job here's how.
  1. Get radiator flush let you car Idle for a while or drive for 15 min.
  2. Let Car cool Down
  3. If no drain PLug remove the hose at the bottom this is the same pipe going into your water pump, Work gentle with it try not to damage the pipe.
  4. open your rediator cap, this will allow the water to train from radiator.
What about all the dirty water inside the engine? this is how to do a decent flush.

  • The car should be cold
  • remove the water pipe at the top of the radiator
  • take your garden hose and insert it to the rediator don't force it just hold it there.
  • Start the car let it idle, open the hose pipe.
What happens now is that the water pump pulls all the clean water trough the rediator and pushes all the dirty water out the other side.
  • when water is clear turn off water
  • kill engine
  • Tighten water hose
  • refill with good Anti freeze anti boil and top op with water
  • drive the car till hot
  • check for any leaks on the pipes you removed before
Hope this Helps

How to check transmission fluid on 2001 isuzu rodeo


There is no dipstick on your auto trans. Checking it is a real PITA The trans pan has 2 plugs in it. The one on the very bottom is the drain. The one in the corner, up higher in a recess is the check/fill plug. To check, the engine must be warm and running, tranny in P. Remove the plug and fluid should dribble out. If it doesn't it's low, fill until it dribbles out, while engine is running. Obviously the truck must be on a lift or up on jackstands.

Peugot 405 diesel Turbo GLX 1995. Heater no longer blows out hot air. I have checked all fluid levels and they appear to be correct. i have flushed the system and topped up. help!


3 things to try

1. in the left hand side foot well, remove the trim at the front of the center console and make sure all the heater control cables and valves move as you operate the controls

2. small cabin temperature sensor - , passenger side, above and to the right of the glove box - grille about 20mm in dia. There is a small fan in the sensor to **** the air in over the temp sensor, but it can in rare cases gives up, and leaves the controller lost and it reverts to full heat or full cold. The fan is little brushless DC job, so you can't do anything with it - got to buy a replacement - which isn't cheap. As a short term, you can hang the sensor out of hiding place which allows it to work sort of. - if you can find a way to get it out
3. the heater matrix is lower than the feed and return pipes - mine was full of radiator sealent (radweld)
drain the coolent water and disconnect the two hose inside the engine bay that feed the heater matrix (they are on the passeger side if your car is right hand drive)
now give the matrix a good flush by sticking a hose pipe into the metal pipes that go inside the car - do this in both directions until clear ------ i had to use kettle descaler and radiator flush left over night in mine.

when you refill make a header tank by cutting off the bottom of a 2 ltr soft drinks bottle, remove the scew cap and wrap some tape around the top of the bottle, and stick it in the top of the radiator
fill the sytem and use the bottle to create a good head of water

make sure the heater controls are on HOT and bleed using all the bleed points
mae sure you bleed it all properly
