You don't. You never open the petcock on radiators with plastic tanks because the petcock always breaks. If it doesn't break, it'll leak when you close it. No pro ever uses the petcock. You loosen the lower radiator hose clamp and yank the lower radiator hose. You'll take a bath, but it'll all be drained in about 1.5 mins. Then reconnect. You'll actually drain far more coolant that way too.

SOURCE: Drain the radiator

Hi There, Facing the engine there is a drian on the lower lefthand side of the radiator. it has a wingnut like head that turns counter clockwise one full turn and the fluid will drian out right below the suport. But be carefull number one its plastic, two it is very hard two get too, I had cut a grove aceoss a 8 mm socket to put over the wingnut shaped pedcock so i could turn it it is almost imposable two get a wrench on it. and three when I was done and closed it, I could not stop a slow slow drip about every 15 sec, My sug is two remove the lower radator hose on the right side, to drain it when its all done and said you wont have this drip problem. If any one knows how to stop that drip out of the plasic pedcock let me know. Thanks

SOURCE: Vehicle is 1999 T/C Limited (3.8L, V6) Leaking in 2 places.

the hoses from the transmission to the gadiatro is leaking. The timing cover might be leaking but acording to what I found from www.autozone.com the waterpump is not behing the timing cover. the hose coming off of the waterpump is leaking. If this helps this is how you remover the waterpump.

  1. Disconnect the negative battery cable.
  2. Drain the cooling system.
  3. Remove the serpentine belt.
  4. Raise and safely support the vehicle. Remove the right front wheel and lower fender shield.
  5. Remove the water pump pulley.
  6. Remove the five mounting bolts and remove the pump from the engine.
  7. Discard the O-ring. Clean the O-ring sealing surface and inspect the water pump for damage, cracks, seal leaks, and loose or rough turning bearings.

If you dont see a white plastic hex nut or black plastic butterfly nut, anywhere on the bottem side you will need to undo the lower radiator hose. Sorry, messy but true.

How do i change the radiator fluid?

Most radiators have a drain plug on the bottom tank the engine block also has a drain plug . Remove the radiator cap ,open both drains ,let all the coolant run out, if there is no radiator plug remove the lower hose , remove the heater demister hoses, with the heater control on hot flush out all the coolant from the heater radiator. with a garden hose, till the water runs clean, tighten the radiator plug or re fit the hose,put a garden hose into the radiator and flush out till the water at the block plug runs clean ,refit the heater hoses, refit the block plug, fill the radiator from the hose leave the cap off , If it has a overflow tank clean and flush it. start and run engine for 5 minutes top up radiator if needed . stop engine and drain out all water. most important that all old coolant is drained out, only buy the best coolant you can . If you make up your own use only distilled water. keep some to top up with never mix with another brand. Fill radiator with coolant top up over flow tank, run engine top up coolant as needed, refit radiator cap run for another 10 minutes check for leaks,

I want to learn how to drain and flush my radiator. I need help on how to do so without making as mess

well its bound to make a little mess but you should have a drain plug on the radiator at the bottom towards the engine side on one of the 2 tanks (sides of radiator ) unscrew drain plug and let drain into a pail or pan ( 2 gallon ) after it drains remove lower radiator hose. use a garden hose and fill radiator and let it flush for a little, hook lower radiator hose back, tighten drain plug and fill with a 50/50 mix new antifreeze,

Ord galaxy 1998 tdi 110 radiator over heating but

you need to flush the radiator out.
With the engine cold, remove coolant bottle cap to release pressure.
Drain engine coolant from drain plug on radiator.
With the drain plug removed disconnect the highest hose connected to a radiator.
use an hosepipe and put it in place of the disconnected radiator pipe.
turn on the water to the hose pipe and let it flush out any sludge accumulated in the radiator. after a few minutes turn off water supply, reconnect radiator hose and drain plug and refil using recommended coolant mix for your galaxy (purchased at most autofactors and garages).
Also check your thermostat as if this is faulty it would stop the flow of coolant running around your engine.

hope this helps

How to flush coolant from 04 suzuki verona, I saw

easiest way is to open drain plug on the radiator let it drain in bucket till it stops refill with water until you get all the coolant out. next time you refill put a cleaner in it and run it down the road at normal operating temperature for about 30 minutes let it cool off and flush it a couple more times with just water when it is clear add antifreeze in a 50/50 mixture one bottle antifreeze one bottle of water.

95 grand jeep cherokee check engine light just came on

you should probably drain your radiator and flush it with the hose. You may need to replace the hoses and make sure they are clamped tightly. It wouldn't hurt to put a little stop-leak in the radiator if its a small leak and refill with antifreeze 50/50.
