Yes, if the radiator fan is not working, it can cause overheating of the engine. The radiator fan helps to cool down the engine by pulling air through the radiator to remove heat. Without the fan, the engine may not receive adequate cooling, leading to overheating.
To change oil in Saab 9-3 the hood will need to be opened and then the oil drained by using the drain pan. With the oil plug removed, the oil can now be changed.
It depends if you get a motor only or the complete assembly. Disconnect the electrical connecter and remove the 4 retaining bolts and remove the fan assembly. Be careful not to hit the radiator.
at the bottom of the radiator is a funky fitting designed to be loosen by hand or a small pair of pliers...you don't remove it you simply drain then refill...also You should be able to find a shop manual at your local library with the right info...make copies as they are usually only in the REFERENCE section....good luck:)
Unbolt and remove the top cover, or metal shroud. This will give you access to the radiator. Remove the rad. hoses and trans. lines. Unplug and/or remove the two fans ( I left them on the radiator when I removed the radiator) then unbolt the radiator and lift out of the car. It will be somewhat heavy if you do not have the fluids drained from it.
I assume you need to get the tanks repaired due to leaking.
- Engine temperature is high - Could also be the thermostat (if no heat from heater) - It is possible to see the fluid flow by removing the radiator cap and looking in. How: Do not do this if the engine is hot or if the engine was recently run. Let the engine cool for 3 hours first. Remove the cap when the engine is cold. Start the engine. As the engine heats up (maybe two minutes) the thermostat will (should) open and you should see fluid flowing. May need a flash light to see into the radiator. - If some of the narrow channels in the engine block are clogged you may hear the radiator boiling after the engine has turned off.
If you are speaking of a radiator in an automobile, there is a plastic bottle on the side of the radiator, and it is marked for the fluid level; "ADD" or "FULL". The cap on the bottle will say "COOLANT ONLY" or words to that effect. Do not overfill. Older model vehicles you will add water to the radiator itself. Remove the radiator cap, slowly, and pour in the water. NEVER REMOVE THE RADIATOR CAP IF THE ENGINE HAS BEEN RUNNING! Wait until it cools down.
Water can be used in an emergency but there is no corrosion protection
like a mixture of antifreeze and preferably distilled water ( until the corrosion
protection in the antifreeze is " worn out " ) Also , adding just straight water
will dilute the antifreeze so the temperature at which the mixture freezes will
not be as low
The coolant leaves the radiator by way of the lower radiator hose then enters the water pump in most automotive engines.
It replaces coolant back into the system by drawing coolant from the reservoir that was pushed out into the reservoir during the heat up process.
