Question about 1999 Audi A6

1 Answer

Coolant Howdy.... Hose connector broke on the coolant, so I replaced it. When I refilled the tank, lost some in the back left corner of the tank, directly under the opening to fill it. It seemed to be a overflow or something, as it leaks at different times.I can feel some sort of round item on the bottom, and it lines up where the coolant leaked out. Is this an overflow or do I have a leak? Marcus

Hi mpullan,
You have a leakage. The tank that you're referring to is the expansion tank.... When the system gains operating temp the coolant exchanges between the tank you're referring and the radiator. When you replace the damaged parts, keep in mind that the system will need to be bled free of air....To do this remember to open the cabin heat controls.

Boiling radiator coolant


This can be caused by the breakdown of the newer long life coolants, the early formulations broke down and do this exactly as you described, have the tank cleaned and flush the system and refill with the newer coolant that doesn't break down and turn to goo.

2002 Caravan,3.3 V6,FWD,had a loose rad cap and lost fluids till no heat in heater.Replaced cap,filled overflow reservoir,ran for a few kms,refilled tank.Still no heat unless motor revs,all levels are...


You still have a lot of air in the cooling system and you have to speed up the water pump to get any coolant to flow through the heater. Let the engine cool off, then open the radiator cap and top off the radiator. Pour the coolant in at a rate slow enough to let the air bubble up without splashing the coolant back out. Once you get the coolant level up to the top overflow hose, the remaining air will be pushed out by expansion through the overflow tank once the engine gets hot, and will be replaced by coolant from the tank on cool-down.

Replace thremostat on 2005 dodge stratus


Instructions Things You'll Need:
  • Drain pan, Pliers, Socket wrench, Socket set, metric
    2.0L and 2.4L Engines
  1. 1 Locate the thermostat by following the upper radiator hose if your car has a four-cylinder engine, or the lower hose if your car has a six-cylinder engine. The hoses are thick rubber hoses that run from the radiator. The other end of the appropriate hose attaches to the engine block at the thermostat housing. Place a clean drain pan below the thermostat housing, then disconnect the hoses from the housing. To remove the hoses, squeeze the tabs on the clamps with a pair of pliers. Make sure that the coolant drains into the pan.
  2. 2 Unbolt the coolant outlet connector from the thermostat housing to reveal the thermostat. It is held in place by two bolts. Remove and replace the thermostat and gasket underneath. Bolt the connector back in place and reattach all hoses you disconnected in the previous step.
  3. 3 Refill the coolant tank with the drained coolant. Run the engine with the radiator cap removed for at least ten minutes to bleed air from the system. Replace the cap.
hope this hepls you.

Hello regikandadam: The coolant recovery tank sprang a leak, the small inlet hose connector broke off, so we replaced the tank and refilled it. The Haynes manual had bleed instructions for 3.8 but no info...


Remove the small return pipe at the tank and point it down and leave the water run out while the engine is runing.If there is air there the water want run out untill all the air is out of the system.Then you will now you will have done it right.

How do i refill the coolant in the car after replacing upper hose


hello, your car has a reservoir tank were you put the coolant in at all you have to do is start your car and it'll draw coolant from there after your car runs a few minutes check your coolant reservoir tank it;ll probably be close to empty also since you took your hose off you'll have air in your system that you'll need to bleed out of the system otherwise your car will over heat and you wont get proper coolant flow the bleeder valve is a small brass bolt that you can use a wrench to open and close it with, with your car running just open the valve until you see coolant flow out then close it do this till you get a solid stream of coolant flow and check your reservoir often while doing this keep it full.
