# How to change iol filter 5.0 bronco?

Remove the bolt from the oil pan and drain the oil from the vehicle into a receptacle. Replace the bolt and then move the pan under the oil filter located on the driver side of the engine. Reach in from the bottom and remove the oil filter and let the remaining oil drain. Take some fresh oil and lubricate the rubber ring around the mating surface of the new oil filter and then screw it back on hand tight. Add oil to your engine till it is at operating level (should be around 6 quarts) run your engine for a couple minutes and check oil level again. It should be about a 1/2 quart to a quart low after the filter absorbs some oil. Add more till you are at operating level again and you are done.

### How do you change air filter on 1992 Ford Bronco?

On the driver's side beside the engine there's a black plastic box with 2 hoses leading to the trottle body (on top of the engine). Take out the 4 screws around the edges of the box and lift the top off. Inside is the air filter. I would recommend spending the extra money (~$50) and buying a K&N high-flow replacement filter (check with your local auto parts store). You'll get as much as a 5mpg…

### How do you calculate difference between a negative percentage and positive percentage?

You calculate the change in percentage points. Thus, the change from -5% to 7% is a change (increase) of 12 percentage points. Do not try to calculate it as a percentage change. The change from -50 to 50 is 100*100/(-50) works out as -200% while the change from 50 to -50 is 100*(-100)/50 = -200%. One goes up, the other goes down but the % change is the same!

### How do you calculate percentage growth if the previous amount is a negative amount?

You do not. Percentage change (increase or decrease) makes sense only if both numbers are positive or both are negative. Consider the change from -50 to +50. You could calculate the percentage change as 100*(new-old)/old = -200% Now consider the percentage change from +50 to -50. -200% again! So, in percentage terms a change from +50 to -50 is the same as from -50 to +50.
