1985 Buick Skylark - Answered Questions & Fixed issues

Do you have primary voltage at the coil, key on? Pink wire, use testlight. How long since a tune-up?

That should be the right port. Low side is the thicker hose and lines. The fittings are opposite for R12 and R134. Are you using an R134 hose connector ?

large wire cliped into dist.cap, powered from ignition swicth

with 3.0L engine the MAF sensor can be check. with screwdriver handle hit a little the MAF sensor while the engine running if it stall .then change the MAF

Physically look in the radiator under the cap(if one exsist's) when cool, for coolant level, and check the valve in the cap for sticking. If air is present in the radiator it can't get out, and more coolant can't get in,(from the overflow). Either clean the cap or replace it and check that it is the CORRECT cap.

If radiator is low on coolant fill it to overflowing, replace cap, and check that coolant overflow is filled to the COLD line or mark. The overflow is normally where you would add coolant. (never overfill the overflow)After refilling as outlined above, check the level every morning for 2 or 3 days until coolant level stops dropping below the cold mark and add coolant to the overflow ONLY. Do not open the radiator cap. Also, if you have even a tiny coolant leak anywhere in the system, air will get drawn in, instead of coolant from the overflow.

For more OVERHEATING PROBLEMS try these...Radiator fins dirty, clean with a strong stream of water, not high pressure water.Radiator clogged, try backflushing it, or replace.Thermostat stuck open or shut, replace it. Or installed BACKWARDS.Water pump worn out, can no longer move enough coolant, replace it.Fan shroud broken or missing....Electric Fan(s) not working, Check the fan, relay, fuse and engine temperature sensor's.Belt driven fan, belt slipping, fan clutch is bad, fan blades have flattened out.

Air dam under front bumper is gone, loose, or broken. It actually has a purpose other than scraping on the driveway or curbs. It forces air up into and thru the condenser and radiator. If it's loose, airflow can actually push it out of place making it useless or blocking the airflow. Along with that, there may also be a plastic piece attached to the bottom of, and wraps up behind the bumper. If it's loose, airflow can actually push it out of place blocking the airflow. Simply reattach it with 4 or 5 screws.Also, if the vehicle has A/C and electric fans, one fan is dedicated to the A/C and should come on almost the instant the A/C is turned on. The engine fan will run even with the key off, that is normal. The system is trying to cool itself. Hope this helps.Normally, you shouldn't have to bleed the cooling system but, there are two bleed valves. (these are the most logical locations)One is just above the water pump, and the other is on the thermostat housing. They are really small, and due to the age of your car, they will be brittle and almost impossible to open without breaking them.You don't want to break them. If you are hearing air circulating thru the cooling system, try this and let me know how you make out.....

replace the head gasket and do a complete oil change

On this model, the mecanic fuel pump is in front on the motor on the passenger side neer the radiator. You have to unplung the 3 gaz hoses and unscrew 2 bolts to pull out the pump.

Loosen Headbolts in this order:

1 5 4
3 6 2

Tighten Headbolts in this order:

3 1 6
5 2 4

Following the tightening order, torque Head Bolts as following:

1. Torque All to 22 Ft Lbs
2. Torque all to 51 Ft Lbs
3. Loosen all 180 degrees
4. Loosen all 180 degrees
5. Torque Center Two bolts to 25 Ft Lbs
6. Torque Outer 4 bolts to 11 Ft Lbs
7. Tighten all bolts 90 degrees
8. Tighten all bolts 90 degrees again

Make sure you tighten all of them down the first 90* and then go back and tighten them another 90*. Also make sure you put some lube between the bolt and the washer, and put some sealant on the bolt threads. Use GM Thread Sealant.

search on ebay, craigslist, local junkyards. good luck finding anything prior to 1990.

a bad ground in the horn button

HI. The firing order diagram you seek is posted below.

if the battery is already charged,it wont put any more in.how do you know the new one wasnt charging.could be a crook battery,get it tested

There was a six cylinder 2.8 liter engine, and a four cylinder 2.5 liter engine used in that vehicle for that year. Here are the firing order diagrams for both engines.

2.5 liter 4 cylinder engine.




2.6 liter 6 cylinder engine.

Its the unit thats on top of your intake, its the round area that sucks in the air.

Sounds like a broken wire somewhere.
Since the middle brake light works I would suspect it is somewhere in the trunk or close to the back seat.
Buy or make a tester. A 12v light with a clip on one wire that you clip to a good ground on the car the other wire with a sharp point. Turn the turn signals on then poke wire to rear lights until tester lights. When tester lights you know the break is somewhere inbetween the tester and the brake lights.

Hope this helps.

You could have one of two problems here. Firstly if you are getting a christmas tree effect on rear lamp assy ie dull glow from all the lights ,, It's most likely a bad earth/ground connection to lamp,,Secondly if anybody has changed rear bulbs or attempted to fix the problem may have inserted a single contact (21W) indicator/turn signal bulb into the Twin contact brake/tail light socket in error . one bulb (21W) has oposite located pin lugs on side of bulb the double contact brake tail bulb (21/5W) has offset pins. Good luck

It's your alternator , faulty diodes and usually a replacement is more economical than trying to repair , ie off the shelf replacement and no down time ! Good luck

The emissions controls unit, the voltage regulator, vacuum lines, head gasket, his habit of driving into solid objects or lack of analytical inclination?

Check for electroplating business. We have one in our area that does bumpers or whatever needs chrome re-done. contact a local car club too if you any in your area, they'd most likely have all those number & connections for you. Even a local bodyshop should be of assistance.
