I'm just going to use this thread to keep track of how much I spend fixing the $500 97 Grand Prix GT I bought awhile back.
Finished:
Replaced the exhaust hanger so my muffler doesn't scrape against the ground.
-Cost: $4 and a half hour of struggling.
Changed the thermostat and gasket. Old themostat opened too easily.
-Cost: $14, thermostat ($8), gasket ($2), and sealant ($4).
Replaced the front right headlight.
-Cost: $8 for the headlight
Flushed the radiator and replaced the coolant.
-Cost: $14 for Prestone coolant.
-Mechanic's quote: $100
Put in an exhaust connector and a metal strapping kit to fix the exhaust.
-Cost: $6, 1 7/8" exhaust connector ($3), and metal strapping kit ($3)
Cut the engine coolant overflow hose (Don't know the technical name). I accidently hit the hose with a wrench and cracked it. I cut about 2 inches off the hose (Where the crack was) and put it back on.
-Cost: Free
Replaced front and rear brake pads. I was originally quoted $400 to replace front and rear brake pads and rotors, but after taking the wheels off I realized the rotors are fine.
-Cost: $30 for front and read brake pads.
-Mechanic's quote: $400 to replace pads and rotors.
Total: $76
Need To Be Done:
Fix A/C. It blows hot air. Will trying charging it, and if that doesn't help I'll look for leaks.
Replace blower motor resistor. Air only works on max setting
Replace front struts. Not a priority, needs to be done but right now I don't have the time or money, so we'll see.
Replace sway bar. The right end link is broken.
