Why does 2000 s40 volvo turbo runs hot and the fan stays on after shut off


fans are designed to run on after you shut engine down as engine temperature rise after switching off . running hot could be caused by the top hose having gone soft when you rev the engine the water pump sucks the hose flat stopping the coolant flow or the radiator is blocked and need flushing out

Can I get a new alternator belt around the fan without having to take it off? This is for an '04 kenworth 18 wheeler with a cat engine.


Probably only if it's large enough to work it over the fan to start with. You can on some cars, but don't know about yours.

91 honda accord fan stars when you shut off engine


There are two fan switches on that car;
The main one turns the fan on and off when the ignition is on and the car is running.
The second switch powers the fan if the ignition is off and the engine temperature is too high, to cool the engine off if it was just shut down.
It sounds like your main fan switch has gone bad and needs to be replaced since it's not sending any signal to the fan, while the engine is running.

The fan on my 96 acura tl comes after i cut the car off and runs loudly


The fan on a 1996 Acura RL will normally run for a short period after the engine is shut off if the temperature sensor determines the engine is too hot. However, if it is running constantly and not shutting off after you shut off your engine, then you will need to replace the fan relay. It is most likely stuck in a closed position. If your fan does shut off after running for a period of time when you shut off the engine but you have a noisy fan, then most likey the fan bearings are wearing out and it is more cost-effective to replace the whole fan. Thanks for using Fixya.

1991 honda drivers side fan runs after engine shut off


If the engine is hot the electric fan will run until it is cool. As long as the engine isn't overheating and the fan doesn't run for more than 10 minutes or so it should be ok. If it has two radiator fans they should both be running though.

91 4.3l won't run hot


You have a TransMission Problem..It's Called a "Torque Converter Lock-up solenoid" ..

When the Engine is cool the solenoid is not being used,
When the Engine is Hot, the solenoid Kicks in and makes your Chevy Run like your pulling an 18 wheeler.

Wait till the Engine is Cool, Slide Under your Van, Drivers side near the shifter is a 4 wire Plug.
Un-plug the wire and see if your trans works after it's hot.. your just by-passing the solenoid BUT I have never found a use for it my self..

IF you still get Lock up after this, you are stuck bringing to a trans shop or see if the solenoid cam be removed without ripping the whole trans apart..

Fan keeps running after engine is shut off


It is normal for the fan to run when engine is off. Engine temps actually rise when the engine is shut off, the heat will rise through the engine compartment. So a Coolant temp sensor controls when the fan shuts on and off, obviously based on the temps of the anti-freeze. The fans are a high draw item, but It would take much longer than an hour breakfast for the battery to run dead. I would check out the battery and charging system first. Is the CEL on? Let me know and we will trouble shoot from there. Thank you for using fixya.com
