I will be storing my 1970 buick skylark in an unheated garage for the winter months and I could like to know?
what I should do to it so that its all prepared to go for the spring, any ideas for winterizing it?

Everything above is good. here is another trick I have learned from storing motorcycles. Shove some steel wool up the tailpipe. Keeps rodents from using the pipe as storage/living space. Rags do not work, they just chew through it. Fiberglass insulation does not work, they will just haul it off for their nest.

first get some fuel stabilizer and dry gas and add to your tank just before your last fill up. check the antifreeze and be sure its a 50/50 concentration. check trans liquid, p/s liquid, and rear end liquid. and change your oil and filter. acids build up in the crankcase and will because corrosion. new oil for storage helps. put mouse traps out under the car. no poison. dead mice that hide in cars will stink. in the spring start the car and warm it up and change the fluids. all the fluids. as well as brake and power steering flush. this will get rid of all the condensation and water that built up in there over the winter. also if your really ocd about cars like I'm get some sea bubble and follow the directions on the can. hope this helps.

Also, increase the car on jack stands so the tires do not get flat spots from sitting in one place all winter. Do add fuel stabilizer like Stabil to the gas and run it before storing to keep the gas from varnishing up. Some guys pull the plugs and squirt some oil into every cylinder hole to lube the rings before putting plugs back in. It may smoke a little in spring. you will have some rust on the brakes in spring that you will have to contend with too. Disconnect battery and charge weekly or better still, run a slow trickle charger with auto shutoff or battery maintainer on it over winter to keep it from going dead.

probably start it up every week or so to warm it up so it does not stall on you or not start up in the spring

Change your oil and filter, flush radiator and replenish with new antifreeze. Test with a prestone tester to ensure there's sufficent freeze protection and disconnect battery to prevent corrosion and discharge. you may be able to keep battery on a charger and once completely charged it'll maintain a trickle charge so its prepared when you're.

1. Clean it completely inside and out 1st.

2. If you do not have a garage with a sealed concrete floor, then your 1st step is to find a suited garage to store your car in. It does not have to be heated, but having electricity could be useful. It does have to be a comparatively tidy, secure, completely closed building with a clean, sealed concrete floor. Parking your car on a dirt or stone surface or on unsealed concrete will let moisture to reach the under cart. Not good. Rust can do bad things to a car.

3. The next step is to wash and wax the outside of your car. Pay special attention to the under cart. be sure there is no dirt, mud, snow, ice or salt from the roads on the frame, or in the wheel wells.

4. If your car has not got a full tank of gas, then head to the nearest gasoline station and fill it up. you will also have to purchase a fuel stabilizer so the gasoline will not turn into gunk while your vehicle's stored.

5. you may want to check the fluids in your car. If any are low, top them off. Change the oil, although, and replace the oil filter also. do not forget to check the radiator coolant if you live in an area of the country that experiences cold winters. be sure the coolant will protect the radiator when the mercury dips low. If not, flush the radiator out and add new coolant.

6. The next step to properly store your car is to take off the spark plugs. Pour some oil into the cylinders to help prevent rust from the inside, and from to get on the pistons and valves also. Replace the plugs and move onto the next task.

7. Unhook the battery cables and remove the battery from the car you are going to store.

8. While you are under the hood, this is a good time to place some smelly mothballs around the engine. Concentrate on wires, rubber hoses and plastic caps things that rodents like to chew on.
