A direct fan output could mean that there is a fault in the system causing the engine to keep the fan running just to be safe. get a diagnosis done, there could be an error in the cooling system or in the a/c system.

This would be normal. As there isn't air flow , then the fan starts turning to get up to speed. The noise is from the fan blades flexing and pulling air threw the radiator. The blades could be a little fatigued. They should have check for cracks when the clutch was replaced. Cracks make the noise worse.

What causes my 1995 chevy pick up 5 speed manual transmission to not want to shift into gears after it gets warm or hot but first thing it does fine


Many internal parts could be the problem. I would replace the vacuum modulator on the passenger side of the transmission first. Near the back. Only thing with a vacuum hose to it.

I have a ford fiesta r reg its had a new clutch the clutch has only been in for a week and half i started having problems when i went to go shopping i put it into gear and i only had a little bite


Who replaced the clutch? if it was a shop then I would take it back for them to fix, If you changed it yourself was there oil on the old clutch and if so did you repair the oil leak. I.e. hyd clutch or transmission seal. Hope this helps.

97 nissan 200sx 2.0, starts but stalls when I shift to forward. Also when in park and reeve the engine up it misses badly. Took distributor cap off and there was oil inside. Other times I can start it...


There should be no oil in the distributor. Replace it. Oil will cause the spark to go anywhere. Most likely to a ground. The distributor base.

My engine is making clicking noises when I start it. This lasts for about 10 minutes.


Sounds like a lifter hasn't pumped up . Put an additive in the engine oil that quiets noisy lifters. Any auto parts store or even walmart has it.

What weight of oil does the my 1995 Honda Accord with five speed manual transmission required to havein it?


many modern transmissions use a 30 grade straight mineral oil in the box but experience shows that a 80-90 grade OEP oil is still the best for long transmission life
However incorrect oil in the transmission will not make it leak or slip as that section is a clutch problem and if you have oil from the bell housing and a slipping clutch it indicates an over full transmission blowing out the input shaft seal and destroying the clutch
the original occasional slipping clutch indicates a problem in the clutch master cylinder or clutch cable and would have been a cheap fix but by allowing a person who is not trained in procedures , the fix will be in excess of $1000.00 as you now require a new clutch kit and front seal in the transmission

Knocking when engine gets hot and car stopped


The fan clutch can make a knocking noise when it tries to engage. At idle it will have a rhythm to it when it tries to engage. You will have an over heating condition and the air conditioning may not work properly.

The fix is to replace the fan clutch and reprogram the engine control module.

Slight hesitation on pull-off with slight autobox shudder


Yes. Sounds like a plugged Trans filter or burned fluid. A full service on the Trans usually runs about $90 and is money well spent.

Another problem-which bugged me for 3 months, and had your similar symptoms, was a worn out fan clutch. It sent a shudder throughout the vehicle which mimicked a transmission issue. I know it sounds silly, but a new fan clutch cured my shifting issues.

The fan should rotate smoothly with some resistance (Engine OFF, of course) If you feel binding of any kinf, it probably is bad. Also check to see if you can cause movement fore and aft. If you can get it to rock back and forth, it is bad and needs to be replaced.

A fan clutch for that vehicle usually runs about $55
