Steering wheel was hard to turn while the engine start...


Most modern cars use power assisted steering. When the engine starts it also runs a power steering pump that builds hydraulic pressure for the system. If the engine has not started there is no pressure in the steering system and the steering feels very heavy.
See this video that explains how power steering works.

Overheating, the old traditional turning on the heater actually brings the temp down to normal. Never had a vehicle on which that the gimmick ever worked. Been told this might be due to fan clutch.


That can be the case, and trying the old heater trick is definitely a last resort. Clutch fans can have the appearance that they are functioning properly, and can even feel like enough air is being pushed into the engine compartment. The clutch does wear out over time, and lose the ability to provide the necessary airflow to cool the engine. One way to test the fan, is to try to spin it while the engine is off. You should feel some resistance and the fan should not spin freely. If you are not sure about the amount of resistance that the fan clutch should have, there is a way to test it. *PERFORM THIS AT YOUR OWN RISK* You will want to put on a leather glove that has a somewhat snug fit, and while the engine is off, hold the tip of one fan blade, and have someone start the engine. You should be able to hold the fan still while the engine pulleys continues to revolve. As the engine starts to warm up, the clutch fan will start to build up pressure, which you will feel gradually building. You should not be able to hold the fan still when the engine is at the normal operating temperature. Before replacing the clutch fan, I would recommend that you inspect and replace the radiator pressure cap if needed, a faulty pressure cap will not allow the cooling system to build the necessary pressure which is needed to cool the engine, and I would recommend that you inspect/replace the engine thermostat if needed. If the thermostat is sticky, it can cause the engine to overheat as well.
I hope that you have found this information to be useful, and if I can be of any further assistance, please let me know. Thank you for using fixya!

Hi just bought i999 1.6 audi a3 and it has started to pulse when idling and oil light comes on when engine reaches nornal temp what could this be please help


If by pulsing you mean that the idle is fluctuating up and down, this is caused by oil/sludge build up in the throttle valve. To rectify this remove the intake pipe at the throttle valve. Use engine cleaner/degreaser on a rag to clean out throttle valve around throttle butterfly. Open butterfly manually to assist access. The oil pressure light coming on is usually caused by the oil pump pick up becoming blocked by carbon and sludge in the oil sump. If you have a suitable oil pressure gauge, check the oil pressure at the oil switch. Oil pressure should be 3.5- 4 bar at 2000 rpm at operating temperature. If pressure ok, Pressure switch may be faulty. If pressure low you will have to remove oil sump and clean out or replace oil pump pick up. If not done, may result in major engine damage. Sludge and carbon build up caused by oil not being changed often enough. Best to use a synthetic oil.

The heater will only blow cold air. THe engine is warmed up but no hot air is being produced. What is the problem?


Start simple, check the coolant level, if it's too low, hot coolant won't reach the heater core, resulting in no heat. If the level drops further, the engine overheats. So check the level 1st, if it's ok, what does the engine temp gauge indicate? Is it running cold, normal, hot?

1998 wrangler 4 cyl 110,000 miles. The engine


quite possibly it may be taking a little while to build fuel pressure. next time try cycling the key on and off 3 or 4 times with out cranking the vehicle to allow the pump to build pressure the try to star it up if it starts right up then your problem is it's just taking time to build pressure

Oil pressure dropping after about 2 hrs running time mainly during a stoplight


first up.Is the oil recently changed.2nd is it the right type..3rd.Oil pressure will drop down when the engine is idling.If, when you give the engine a rev and the pressure builds straight back up,there is not a problem.Its normal.Cold oil will always give a higher pressure than hot oil.Check these few things and I hope this helps
