You should be able to go to most any hardware store or locksmith and ask for a keyblank. You can also look for a ILCO B102-P which will work with your Astro.

Another option is to google (or your favorite search engine) the ILCO B102-P and you can find online vendors who sell the keys. Most sell them in 5 packs but they are usually under $1.00 / key + shipping.

When you put the converter in the trans did you make sure it was all the way into the pump? it will go into the pump slots when you turn it, when it does you keep turning it and it will fall in alittle more, Without going into a lot of detail here sounds to me like you got a bad trans.

on the engine compartment on the fuel rail there is a pressure port that is usually covered by colored plastic cover open it then turn the ignition switch listen for the sound of your fuel pump turning on momentarilly. if you cannot hear it while ignition is on insert small screw driver on the port to open the valve make sure you wrap rugs to control the flow of fuel if there is any. the fuel should around 40-50 psi so expect heavy fuel coming out at port if your pump is working. to change it you have to drop your fuel tank and replace your pump. this is usually left for professional due to fire hazard. any spark due to static electricity can set your fuel to flame up.

Great news for you, the best way to drain the radiator is to remove the lower radiator hose. The bad news is that OEM radiator came with no drain plug and you can have one put in after you remove the radiator to drill a hole and tap in a $6.00 radiator drain plug for NAPA auto parts. Good luck and hope this helps. this was a way for GM to save money by one less parts to have make, since most auto mechanic just remove the lower radiator hose to drain the radiator. Good luck and hope this helps. If your luck and your Astor does have one, you can find the drain plug on the lower drivers side of the radiator, engine side.

are you changing the filter ?
are you allowing for all the oil to drain out ?
did you start the engine at 3.5 than shut off wait & recheck ?

it could be your thermostat heater core or dirty colant

you need to start by taking off the inside of the door and then take the three bolts on the side of the door where you see the latch undo the handle from the inside of the door put the new one in and go in reverse to put it back together

sounds to me like you have a rear temperature door motor not working, remove rear left side panel to gain access to the heater box. and it will be the top acctuator twards the rear sells at dealer for @ 60-70 bucks

Typically newer vehicles run at a normal operating temperature of 195 degrees to 205 degrees. if anything it's running a cold, which would waste fuel.

There is a vacuum hose that runs in front of the throttle body going to the vacuum ball the hose is part plastic they get hot and break.With out this hose attached the blend door actuators will not move.

Sounds like it could be a bad mount. Maybe engine, tranny, exhaust??
