1. Change oil and filter. 2. Make sure there is water in the radiator. 3. Check transmission fluid level(the vast majority of '79s had automatic trans, use tranny dipstick) 4. Pull all the spark plugs and spray some WD-40 into each spark plug hole then let it sit for awhile (this will help break the piston rings free). 5.Turn the motor over by turning key to start position and holding it there about 5 to 10 seconds (don't want to overwork the starter). Do this 5 or 6 times, this will push new oil through the engine. (leaving plugs out while doing this will let the engine turn over easier) 6. Install new spark plugs if needed, connect plug wires. 7. Dump some gas into the carb (don't be stingy). 8. See if it starts, keep trying. If it does start, it probably won't run very long because of the old gas.(even if it wants to, don't let it)
9. IF IT RUNS AND YOU WANT TO PLAY WITH IT SOME MORE, DO THE FOLLOWING: Flush cooling system (Prestone flushing kit, cheap and easy). Change tranny fluid and filter (DO NOT have tranny flushed!) Drain old gas by disconnecting fuel lines and allowing to gravity drain into gas can, etc (using fuel pump to do this by turning key on will not work, '79s did not have electric pumps). Don't forget fuel filter. (NOTE: carb might be gunked up and need rebuilt.) Fan belt need replaced? Don't run too much without changing oil again.
Also if this becomes a driver, flush brake system.

Ok.. oil simply change it and the filter don't forget to add oil to rubber ring.. water jus unhook the hose at the bottom of the radiator using pliers and make sure you have a drain pan.. you can run water through it if it is unclean, otherwise you shouldn't need to flush, then reattach hose and clamp.. fill to top.. the water pump on the vehicle will need to be rotated or cranked to get water into the engine, and refill... be careful not to crank the water pump by hand because that will mess up the timing and you will need to redo that.. tranny fluid should not be changed because if there is a certain amount of metal shavings already in it clean fluid will ruin it, but i suggest checking the fluid level and maybe topping it off if needed there should be a bolt on the side of the transmission that you can take out and put your finger in the hole and the fluid should reach the hole and no lower if it pours out its fine let it level out too much tranny fluid is just as bad as not enough.. you will need to have the car on jack stands as level as possible to do this... also you can disconnect the fuel lines at the carburetor and connect a hose to it turn the key on and the fuel pump should pump out the old gasoline..

I dont know what year model you have but the newer one will run when car is turned off to cool radiator. Maybe you have a radiator problem if this just started to happen. Is the car over heating. Did you check radiator fluid or thermostat. I dont know much about your car and year model but i would do these checks. Maybe radiator needs to be flushed. You can use aluminum brite for to flush. Can buy it at O Reiley's. I had to flush my daughters radiator about 10 times when we bought it used, fithy. Looks brand new. Please dispose of chemicals properly. It is an acid.

How much transmission fluid needed to flush a chevy impala?


Just do a pan drop & refill

Your asking for trouble flushing
with a flush machine at a repair place

If the fluid hasn't been changed every 3 years
since the car was new they can slip from complete
fluid changes

Just add 3 qts check level,add more & warm to 180 or more
& check again hot

How do I change rear brake pads on a 2007 Mercury Mariner


Rear disc & pad work is no different than any
on the front of vehicle

The only difference is you need a small tool
that is about $9.00 to turn the parking brake
adjuster in while pushing in the caliper piston

On the front you use one old pad & a large
C clamp
On the rear only push by hand as you turn the piston
clockwise. Two functions in one
Open the bleeder valve helps

I do hope but don't expect that you know that brake
fluid gets flushed every 2 years on all vehicles

I will add Power Steering & Transmission Fluids
every 3 years & not more than 30,000 miles EVER

If you don't you will have expensive ABS problems,
the steering rack will fail, as will your trans

No one on this site but me provides an education
The pros may not appreciate my comments but
the auto repair industry has zero chance in my
opinion, of ever dealing effectively with the motoring
public

I have a 2001 Dodge Caravan SE 2.4L 4 cylinder motor. I had the transmission flushed almost 2 years ago and since then have put 12,000 plus miles on it. All I know is you are suppost to check the...


You need to, at the minimum, change the fluid & trans filter. Easy proceedure. With van jacked up & blocked so it won't fall, use a large collection tray under trans pan & remove pan bolts. let oil drain into tray. use screwdriver to pry pan off. clean pan thoroughly & trans matting surface. Remove filter. You may need to adjust low rev band. Check with dealer or parts store for proper clearances. Put new filter on & tighten bolt[s]. Use new gasket & rebolt pan. Use gasket sealer on pan side only. You'll need 4-8 qts. of the proper tranny oil. Fill through trans. filler hole. Start engine & let warm up, check level & don't overfill or you'll have to suction out until level.

Maintenance Toyota Solara 2000


I have kept my cars running for a long time (250k+) by changing fluids as u are doing, and fixing things right away, not letting them develop into bigger problems, so u are destined to have your car for a long time! Many of the maintenance items u list are typically NEVER done by anyone, but they should be. Here's what I recommend from many years of maintaining my cars:
ps flush-50k or 5 yrs
brake fluid flush- every time u have brakes replaced.
Rad.drain, flush, fill -new coolant is said to be good for life of car, I would flush and refill 50/50 coolant water mix every 4 years.
Fuel Injection- I'll get flak over this, but I never do anything to the system, just change your fuel filter every 2 years, or 20k
Trans Flush-don't have it done if they '**** out' the fluid from the dipstick tube. I consider that method a waste. Have the pan removed to drain it, and replace the trans filter if equipped w/ one (u can't change the filter if u **** the fluid out of the dipstick.) Also, some vehicles have a magnet on the bottom of the trans. pan, which collects fine shavings from normal wear and tear (and pieces of metal from a trans. about to go bad). U need to drop the pan to clean this crud off the magnet.
oil and filter (good quality filter-cheap junky ones are much lighter than a quality one) every 3k or twice a year whichever comes 1st
I'll add: air filter- every 20k or once a year
check tire air pressure once a month, rotate tires for even wear (every 5k miles) Can I buy your well maintained car when u r ready to sell it?
