Compressor is probably seized due to lack of oil.

Smoking belt


Not knowing if you have a single serpentine belt or separate belt for the AC compressor, this is most likely the compressor bearings out. If the belt is smoking, and it has its own AC compressor belt I would recommend cutting the belt off so it does not break and cause other damage under the hood.

Smokes and smells like gas at muffler


That has to be gas that is not being burned! No idea why blowing a fuse with the air compressor rashed your car like that - must be coincidental or collateral damage.

2005 Ford F250 6.0 turbo diesel blows black smoke out exhaust and has no power when I try to excellerate.


1. check charge air tube,loosing boost pressure=low power and black smoke
2. check for air filter restriction,if it cant breathe it will blow smoke and run like ****
3. check for rotational drag on the turbo compressor wheel, it may be locking up causing low power and black smoke, much like cummins vgt turbo
4.oil quality,poor oil quality, ie long intervals between oil changes.
5. may have a leaking injector, not common with this style of injector but i wouldnt rule it out if nothing else checks out.....hope this helps.

Can you tell me exactly how to fix my air shocks.....is there a manual pump?


System has no manual pump.system overview is this,air springs at all four wheels,electric valve at each spring,air line from these valves to a compressor under hood and lastly level switches that look at height and run compressor and open valves according to need.most likely the air spring bags are cracked causing leaks to system in turn which over works the compressor.best hope is just no power to compressor,so test for power and ground at compressor and if no power.power it up and raise veh or if there is power the compressor is smoked.

Ford f25 1991 the heater belt starts smoking when turn on. We do not use the air conditioner


I would take off the belt and check each pulley for free movement when the car is off. For example, if there is an air pump, it should turn freely. Or, if the alternator pulley is disconnected from the belt, it should turn relatively freely.

White smoke out of exhaust on start up. what is the cause and the fix?


Really light smoke often appears blue. That light blue smoke as well as white smoke is oil smoke. (That is why some people will insist that oil smoke is blue...)

That is oil that has seeped into the combustion process. That most often is valve-stem seals/valve guides. The oil under the valve covers on top of the heads runs down the valve stem as the engine sits. (It is pretty unlikely that oil would seep up, past the rings...)

If that is the case, removing the heads and having the valve guides really fixed is the best solution.

You can inspect this problem without that level of disassembly, though.

After removing the valve covers and spark plugs.
Turn the engine to get a piston near TDC (but not quite at TDC). You don't want the vale to be able to drop into the cylinder, but you want a little room between the valve and the piston top.

There is a type of valve spring compressor that has a pair of prongs that grip the spring, with a hand-wheel on top to push down on the retainer.
Use a valve spring compressor like that to remove the valve-spring-retainer keepers, the valve-spring retainer and the valve spring(s) from 1 valve. Check the side to side play to see how the guide is. Check the condition of the seal. Check all the valves this way, unless you find right away that there is enough wear that rebuilding and reconditioning the head is necessary.

Smoke around belt


the smoke is coming from the belt because a part has stopped turning ...you need to check which one it is... it could be the water pump...alternator ..a/c compressor...... power steering pump or the belt tensioner.... and your going to need a new belt
