Volvo c70 carbriolet modle 2006 oil ranning in to the cooling water tank what causes that?


if it is an automatic transmission the problem will be a split cooling tank that is inside one of the radiator tanks
the fix is a new radiator and a full flush of the cooling system

I have a T reg Peugeot 106, the temperature light keeps coming on even thou I've topped the oil up. Any info plz


Topping up the oil has very little bearing on engines overheating.

You need to remove the radiator cap and top up the cooling system with anti-freeze and water mixed to specifications. Note that I mention RADIATOR CAP and not the expansion reservoir cap. Remove the radiator cap with the engine COLD. Once you have filled the radiator, you need to run the engine until it gets to full operating temperature. Some of the water will overflow out until the thermostat opens, then the water level will rise and fall. When it has settled, bubbles have stopped, turn the engine off, top up one last time. Replace the radiator cap and then top up the reservoir tank.

There are videos online, Google 'burping cooling system', and look at the images tab. Here you go.

Got a 311cdi mercedes sprinter ,mileage is 250k drives well but engine is making loud tapping noise & there is oil in radiator. please help.


Your low on oil (the tapping noise) because its in your cooling system. Your vehicle uses the radiator as a cooling system for your engine oil. It runs through it to help cool the engine oil. If you have oil in the radiator, you need a new radiator before you cause more damage to the engine and the cooling system.

I have a 2006 chevy aveo and it runs hot when I run the air conditioner and the radiator tank is empty, when I put water in it, it makes a crackling noise and then when I try to give it gas to make it go...


Does the empty radiator have anything to do with the AC? OR is it always empty? You should fill the radiator and the tank when the engine is cool. Never take the radiator cap off a HOT engine. It can shoot hot steam and water all over you and cause serious burns. With the engine cool, take the radiator cap off and fill it with the proper coolant, not just water. The coolant instruction label should be on or near the radiator. Fill the radiator completely, You may have to finish it slowly because of air trapped in the system. You can run the engine a short time to assist in filling the radiator. When the engine is running, if a lot of air bubbles out it could have a blown head gasket. DO NOT ALLOW THE ENGINE RUN UNTIL IT GETS HOT. If there is air in the system the coolant will go down and you can continue to fill it. When it is completely full, shut off the engine, top off the radiator if necessary and put the cap on completely and tightly. Fill the coolant tank to the full mark with the same coolant as the radiator. Drive the car and see if it overheats. If it smokes and has water coming out the exhaust, it probably has a blown head gasket. After it cools, check the radiator again. If it is low or out of coolant, again - blown head gasket. A blown gasket can **** coolant into the combustion cylinder OR can blow exhaust back into the cooling system. It can also allow motor oil into the radiator. Look for oil when you are filling the radiator. Also check the engine oil, if it has coolant in it, it will be a thick gooey mixture. In either case you should have the car towed to a qualified mechanic for testing and repair. If none of these things are occurring, look for a leak in the coolant system. A bad hose, or a leaking water pump. A defective radiator cap or the cap is not on tight. Look for the easy things first. Good luck.

1999 chevy tahoe 5.7L vortec 350 new thermostat,new radiator,new waterpump.still overheating?


REPLACE RADIATOR PRESSURE CAP AND CHECK THE COOLING FAN CLUTCH.WHEN YOUR ENGINE HOT WHEN YOU TRY TURNING CLUTCH FAN WITH YOUR HAND WHEN ENGINE IS HOT.THERE SHOULD BE RESISTANCE IN THE FAN.IF CLUTCH FAN SPINS FREELY WHILE ENGINE HOT.YOU NEED TO REMOVE COOLING FAN TO REPLACE CLUTCH.

Over heating -The water resevoir is full,but the computer keeps telling me to re-fill.Also the cooling fan is running almost permanently?


Just because the overflow reservior is full does not mean that the rest of the cooling system is also full. The engine itself is very low on coolant and running hot as indicated by the temperature guage showing hot and the cooling fans running continuously. You obviously have a leak in the cooling system caused by either a faulty hose or radiator which is leaking once the system pressure increases as the engine heats up.. The rubber hoses in the cooling system can go hard and start to leak where they attach to the metal piping around the engine as they get towards 10 years old. Thoroughly check all hoses including heater hoses and the smaller bypass hoses around the engine for splits or leaks. Stop engine and allow to cool, replace any defective hoses or hose clamps and then refill radiator. Restart engine with radiator cap off and idle engine with heater control on full until it reackes operating temperature while continuing to add coolant until the system is full once again. Allow the cooling fans to cycle on and off a few times to ensure there are no air locks in the system. .Hopefully you have not overheated the engine to the point where you have caused a problems with the head gasket which could allow coolant to leak into the sump. This will be indicated by the dipstick showing a milky emulsion instead of just oil on it. If the haad gasket has failed, it will necesitate removal of the haed, have it machined, and then replaced with a new gasket. Not a cheap exercise.

    5. Disconnect the transaxle oil cooler lines from the radiator.
    6. Remove the radiator brackets and bolts.
    7. Remove the radiator. Installation Procedure
    1. Install the radiator. Notice: Refer to Fastener Notice in Service Precautions.

      4. Install the cooling fans with the cooling fan shroud.
      5. Install the engine mount struts. Notice: When adding coolant, it is important that you use GM Goodwrench DEX-COOL (R) or HAVOLINE (R) DEX-COOL (R) coolant. If Coolant other than DEX-COOL (R) or HAVOLINE (R) DEX-COOL (R) is added to the system the engine coolant will require change sooner; at 50,000 km (30,000 mi) or 24 months.
      6. Fill the cooling system.

Oil in the radiator


are you sure its oil in the antifreeze? oil is brown. your van should have dexcool wich is orange, not green.(looks red sometimes)check the coolant again and check the oil. if it looks milky or foamy, there is coolant in it. sounds like it may be a blown head gasket. not good. stop driving it if you want to save your engine. you need to replace the head gasket/s, and flush the cooling system.

Overheating and change engine oil ... oil was changed one week ?


it seems like the radiator of your car needs attention. check for coolant level in it, when its cold. if les add some coolant and then see if the problem persists.
--than there are chances of chocking in the coolant pipes, may be they not reached to engine..  
--Check the chock,, that it is not turned on. 
--May be sum loosing nut in engine.
