The PVC valve is located on the back of the engine, behind the throttle body. Mine is a 300 engine (6 cylinder) should be in the same location on an eight cylinder as well.

I am no expert; but, according to my Montana repair manual, the blower motor resistor is located under the dash on the passenger side. It can be accessed from inside the car. It's located behind the fan motor

remove ht leads and get a 10mm sparkplug socket from your local tool shop. if you cannot gain access to number 2 plug, remove the ht coil box by removing the two screws on it first. use a socket set and a torque wrench to put them back in. set the wrench to 30nm.

Your local autozone can tell you. If they can't ask for spark plus for a 1988 Ford Thunderbird with a 5.0 engine.

if you are talking about the automatic sensor that automatically turns the lights on and off, it is on the dashboard probably in between the defroster vents it is probably a small plastic or glass bubble usually you have to remove a large portion of the dashboard to replace it

The spark plugs are located on either side of the engine underneathe the two rectangle shaped black plastic covers. Do yourself a favor, unless the vehicle has over 100,000 miles and/or your gas mile/performace is dropping, don't have the plugs changed. They are hard to get to. If you're not very mechanically inclined, get the dealer to do it.

It depends on the year, make and model because some will hold as little as 1.0 pound while others will hold 4 plus pounds............

Take off the engine cover. There should be four Phillips head screws and it will pop right off. You will see four black box looking things. These are individual coil packs. Take those out by either pulling, or on some models they require taking a hex screw out, and proceed to taking the spark plugs out.

Replace air pump

It gives you all the blower motor speeds except high.

all blower motors are 12 volt, so on full speed they turn fast and blow a lot of air, to make the fan turn slower [and blow less air] they route the power through a resister, it drops the voltage to the motor so turns slower, on a 4 speed motor there will be 3 resisters.

Does the Pontiac 3.1 Liter sfi 3100 V6 have any problems?

If this happens, usually you crossed the threads on the head.

follow the thick black wire from under the fly wheel cover it goes to the spark plug

freeze plug has blown out or leaking

There should be a sticker by the radiator to verify the engine size but barring that, I'm pretty sure the only 6 cylinder engines put in 1965 vans was a 230 cu. in. inline six. The only other 6 cylinder available was a 292 but those were special order for pickups. I doubt they put one in a van.
