How to remove the air filter housing on a 1998 s70 volvo

Check your owner's manual but the filter housing is located behind the left front headlight. Simply unsnap the clamps that hold the top on though you may have to loosen several hose clamps as well, then lift the lid off, pull the filter out and before putting the new one in, check for debris in the bottom and clean out first. It's just that simple. Ten minute job

It has been my experience that both radiator hoses get hard with age, check the hoses for age and cracking because they usually are hard right before they give out. They get hard when they get old due to excessive oil covering because of an oil leak and heat from the engine and the coolant within the hose.

Hi Steve:

The first thing to do is remove the negative battery cable, this will wipe out the presets on you radio and Nav if you have it. If this is not a problem the next step is to find the drain if it has one. You should collect as much of the fluid as possible. You can dump it down the toilette if you have to but dumping is in the storm drain will kill fish, dogs and other pets. They will drink it, it is sweet and it is poison. That said consider replacing the hoses at the same time you will probably damage them and you don\'t want to do this job twice.



Open the radiator cap.



Remover the lower hose and then the upper hose. Some cars and trucks also use the radiator to cool the transmission if this is the case there will be two additional steel tubes attached to the radiator. Spray the threads with liquid wrench or another good quality penetration oil. WD40 is not a penetrating oil. Buy the liquid wrench.

If you are removing the transmission lines you will want to invest in a set of tube wrenches. This might seem expensive but if you strip those nuts you will wish you never tried this job. You can buy them at sears or most auto parts stores if you don\'t have them.



The AC has its own condenser coil, it usually sits in front of the radiator. The condenser coil has aluminum tubes do not disconnect them.



I guess at this point I assumed you removed the cowling. If not you will need to do so. I don\'t know if you have electric fans or a belt driven fan. Some times if you have a belt driven fan you can just move the cowling back and not have to remove it completely. If you must remove it completely you may need to remove the fan first.



With that out of the way there should now be two bolts holding two clamps with rubber bushings holding the radiator in place. Remove these and your ready to remove the radiator.



Best of luck

It is on the engine side of the Air Filter right on top of the filter housing hooked up to that big tube that goes to the Turbo Charger.

That's not a problem as far as its not overheating. and if the radiator is bad or there was a leak then the car will be high not low. and i think your your Thermostat is open all the time that's maybe why the car is always Low on Temperature.

Hope thats help (remember comment and rated this).

The fuel filter can be located under the carpeted cargo storage floor at the rear of the wagon. Remove the four 10mm bolts, remove the cover. You will then see a removable plate to the right just behind the rear passenger seat. Fuel filter can be seen through hole in hole. Replaced from underneath wagon. Be sure to make sure lines are fully inserted onto filter. Check for leaks. Note arrow on filter for correct fuel flow. Good luck and hope this helps and no smoking please LOL

If the air pump system is setting a fault, then the check valve is probably bad. If it is not addressed, eventually exhaust gases can run back through the air hose to the air filter housing and destroy the MAF sensor, causing these types of problems.

The fuel pump also fails and is a more likely cause of the stalling, and it wont set a code.

from he Popular Mechanics site if the smell in your car is like maple syrup:


(1) SMELLS LIKE: MAPLE SYRUP
WHEN: After the engine has warmed or possibly even after it's shut off for a few minutes.
THE CULPRIT: Coolant containing sweet-smelling (but toxic) ethylene glycol is leaking from somewhere. It could be coming from a radiator or heater hose, a failed intake manifold gasket or cylinder head. It might be coming from a leaky radiator cap or the radiator itself, especially if you smell it outside the car. A strong odor inside the passenger compartment probably means a bad heater core.
