SOURCE: How to change a spark plug on a 2001 murcury cougar

Front plugs V-6 remove engine logo cover and air boost box, use looped end longe needle nose pliers to grip boots at base and pull up, easy to do when engine is still a little warm, I use a Thorsen brand spank plug socket and 12" extension, the Thorsen does not have rubber boot which may stick to plug when installing.Rear plugs, remove the 3 bolts on coil pack, slide back an inch, use same tool to loosen boots from plugs, use same 12" extension and socket that you used on front, there is just enough room for that extension to slightly rub rubber hood seal on firewall. remember to properly gap plugs .052-.056" and to hand tighten them first before placing ratchet onto extension so you know plugs are grabbing threads properly. I just performed this job on my 2001 V-6 Cougar and took just around 30 minutes, no need to spend many hundreds in a shop to change your plugs... another tip, if you have air, blow the spark plug pockets out after you remove the plug wires in case any were loose and debris had fallen inside, mine were pristine...

Over heating while pulling a trailor

Make sure fluid levels are full, including transmission, engine oil, and antifreeze both the radiator and overflow. Note: make sure the air filter is clean so the engine can breathe easier too.( like trying to run a marathon breathing through a straw, you will get hot/overheated quickly too) Check fan(s) to make sure they are operating properly, (inspect the blades for correct shape/bends) some clutch fans can wear out, You shouldn't be able to just free spin them, they should have drag to them (check this while the engine is cold and off) if you have electric fans make sure that they are coming on. Lastly check the radiator fins, make sure all bugs and junk are cleared from them that way air can pass through with no obstructions. Hope this helps, happy hauling

Spark plugs keep oiling up..not always the same one, goes well after cleaning, but only lasts a day.

I would recommend doing a compression test to see if your rings don't have any leek by.And it could also be leaking valve guide seals.

I need to know what would make my 92 ford explorer 2wd 4.0 v6 get 6 to 11 mpg changed the plugs wires changed the injeters and the fuel presser regerlater last year don't hot rod it let get get up to speed...

That does sound like a very low MPG for your V6 and 2WD.....

Check your spark plugs - see what color the deposits are. If they look tan, the engine is running correctly. If they have a fluffy black deposit, your engine is running rich. Make sure your air filter and the breathing tube are clear.

The most likely cause if your plugs have a normal tan deposit on them is one or more brakes dragging. Make sure all your wheels spin freely when off the ground (use wheel chocks on the other wheels for safety's sake.

Often, the emergency brake cable hangs up and will cause the rear wheels to drag, ruining fuel economy.

Easiest access to replace #1,3 ,5 spark plugs on 3.4 lit v-6?

There really is not easy access. You will have to climb on the car motor and follow the wires down to the plugs. Use a 3/8" socket with a spark plug boot and swivel. It will make things easier.

My odyssey is consuming fuel more than the normal. it gulp 75 litres for a journey of 220miles

Start from the ground upwards. Check tire pressure, jack up wheels and spin tires to check for brakes dragging. Then spin tires again and listen for roughness in the wheel bearings.

Some of these vehicles need alignment on both the front and rear wheels. If tires are not running parallel it will create drag.

The usual measures for clean oil, filter, air filter and so on. If you have not seen a "check engine light" most of the components must be okay. A 6 year old vehicle should have a set of spark plugs after 50,000 miles or so.

The gasoline is not always good either. The gasohol has a lower energy content so you do not get as far as with 100% petrol. That's about all I can recommend at this point.

How to change a spark plug on a 2001 murcury cougar

Get a swivel fitting for your socket wrench. You may also need a short extension for the socket wrench. You will also need a spark plug socket to fit those plugs. Make sure that you pull the plug wires off by gripping the fat part of the plug wire and not the wire itself lest you tear it and ruin it.
