on servicing my car HELP? i just bought a 1991 lx coupe 2.3l mustang the fluids are NASTY coolant reservoir is orange oil dipstick smells foul and has alot of gunk residue transmission fluid has an un-ordinary stench

my question is how should i go about changing my fluids and is royal purple and zmax a good choice?


-how to drain coolant?
-how many bottles and which type of royal purple oil?
-how do i drain my tranny fluid since theres no plug? and how many bottles of tranny fluid do i use to fill it back up?
-when do i remove my oil filter? and when do i put it on?
-do i put the zmax in after im done with changing my oil?

need step by step instructions please thanks!
 
Drain coolant from drain valve on the bottom of radiator. If it doesn't have one pull off the lower radiator hose.
Should take 4 or 5 quarts of oil. Drain oil and then take off filter then put new filter on.
Trans pan has to come off to drain fluid.
You don't need royal purple or Zmax. Any cheap oil is fine for that thing.
You might get a service manual it will help with all these procedures.
