Try looking in the manual or on volvo's website(they should have online manuals. and i think you are looking for the coolant fill bottle. it should say "caution, high pressure, do not open when hot" or something similar. if i am not mistaken it will also be full of ither green or pink(original) liquid. if you cannot tell, then opn the caps of different bottles(over 2litres) under the hood, the one that smells 'sweet' or similar to the coolant that you are putting in, is the 'rad' cap. (they don't put the rad caps on the actual rads anymore)

Hi my name is paul
these days most cars have a expansion tank under the bonnet or hood
this is were you fill it up with water it looks like a plastic bowl with a screw lid
DO NOT UNDER ANY CIRCUMSTANCES UNDO CAP WHEN ENGINE IS RUNNING OR IS STILL HOT *** DANGER OF SCALDING DO NOT OVERFILL CHECK OUT MAX LEVEL
car manufacturers use expansion tanks because as the water in your engine warms up it expands under high pressure and fills up the expansion tank with excess water when the engine cools down the water cools and it shrinks and goes back into the cooling system hope this information has been usefull
regard paul

What's the first few things to check when my heater isn't giving me any heat. Car is a 1994 Chevy Camaro.


you have air in the system ,if you have not done a radiator clean ,the put radiator flush in the radiator then go for a short run.about 5 miles then go back and drain the radiator.now remove both radiator hoses.fill with water it will pour out as you do so..if clear refit you hoses.fill will a 50/50 mix of antifreeze. now put your heating on full open your window .with your expansion bottle cap off ,run your engine on tick over till the water starts to head up.then refit the cap.this is done to bleed the air out both in your heater core .and the radiator.

I have a volvo 940 1994 and I have replaced the water pump but it is still overheating sometimes which makes me think of the thermostat and if so where is it located and I want to replace my timing belt is...


if the thermostat is broken the fan should keep turning. Check the fan if it spins once you get the car warmed. Otherwise it could be a blown fuse or relay for the fan or the fan itself may be bad. Check the radiator hoses and the radiator cap for loose or worn parts. Steam may escape there decreasing the water in the cooling system. The problem could be also be with the water pump. If you are to replace the timing belt have the water pump replaced since you will spend the same effort getting to both the timing belt and water pump. It is recommended that this be done by a specialist to avoid damaging the engine.

1997 VOLVO 850


check for compression on all cylinders if you ran the engine hot to long you may have blown the head gasket another way you would know is by filling up the radiator with water and then with the cap off turn the starter like if your going to start the engine if you see the water jump out of radiator then you have a blown gasket another way is by checking the oil if it looks like coffee with milk then the gasket is blown, I hope this information is useful good luck

1987 Volve radiator cap location


there is a tank for holding radiator fluid mounted one one of the wheel wells inside the engine compartment. you should hopefully be able to see the level on it. add antifreeze there to the level marked on it.
it's safer for you ... the motor and the environment to have it that way.
