I have to drive to mississippi in the beginning of august however, so i will need to get a tune up before i go. my first question is regarding the a/c. My ac only blows hot air, but this doesn't bother me really since i very very seldom use cold ac (like the windows down) in my vehicles as i prefer them warm. I checked the coolant level in the reservoir today and it was a little less than the add mark (engine was cold). the fact that it is a little low, can this cause this, eh, issue? the ac was fully charged and it didn't solve it (although it was charged at grease monkey  ) so i'm assuming the compressor is fine and the fuse was good too. this would mean that it was low when i first got it but the coolant temp seemed fine from day one, it usually stays in the middle of 100-210. the second thing is about the tune-up itself. I am a little low on funds for this so i think all i'll be able to do is change fluids. what should i tell the shop to use when i bring it in? regular? synthetic? specific brand names that work well on these vehicles? Also, what fluids should i service (oil, coolant flush, power steering for sure) before i take this long journey (putting a good 2300 miles on that week.) i probably can't spend more than 250-300 bucks(labor at 70/hr) if my grandma doesn't help me with gas. |
Did grease monkey do a death kit recharge?
Wal Mart DEATH KITS
You cannot properly and safely recharge an air condition system with them.
The one side stop and go gauge does not tell you what your system is doing or is over charged or undercharged.
A overcharged or malfunction air condition system can reach over 500 lbs of pressure.
Enough to blow up that can or system and freeze you at first and the burn you or blind you and if any propane /butane in there blow and light you up.
The stop leak crap and who knows what kind of oil in the kits there will stop your system for sure.
Just like pouring super glue in it.
And some kits even contain freon with a butane mixer.
Good for a big blast.
If you are going to do it do it right and safe.
Here is what you need to start with.

In the older days you could just throw in a can and go.
But over the years just adding freon is getting harder to do.
Newer systems have to have the correct amount of freon down to the ounces.
Most will need pumped down and vacuumed down and the right and amount of oil and a set amount freon charge installed to get the air to cool right and the system to last.
If an air condition is low there is usually a leak that needs fixed and also a lose of lubricating oil from system.
Also air and moisture enters a low system
If you are going to try to do it get the proper type air condition gauge set with the low and high side gauges.
Hook up the gauges and get a reading with compressor running at idle and at 2000 rpm on the high and low side.
Post back pressure reading and we can help you.
