Forgetful

Hello, I'm planning on picking up a 99 FRC with 92k on Friday and was wondering what the recommended maintenance I should do for it? It hasn't been driven much supposedly in the last couple years.

​​Was planning Oil+filter, diff fluid, transmission fluid.

Do the other fluids too......brake, clutch, antifreeze, power steering.........

Congrats on the "New" Acquisition....

If this is your first time owning a C5 then may I suggest these two posts as an almost MUST READ. Plenty of important and useful info.

Another thing, you did not mention if it's an Auto or Manual trans. If it's an auto I'd drive it for a while and see how the trans shifts etc, etc.

Check the condition of the brake pads and rotors. Make sure the tires are not dry rotted from sitting. Safety items first.

All fluids, oil, trans, diff, coolant, brake, PS.

Replace air filter and clean out the condenser/radiator as these cars tend to gather debris from underneath.

Clean out the 4x udders under the front cowl.

Drive it and see what needs attention (creaks, groans, clunks, bumps).

MAKE SURE that the BATTERY is 100% ready to support driving the car. I STRONGLY recommend having it TESTED to be sure it has proper Cold Cranking Amperage (CCA) & most importantly the proper RESERVE CAPACITY!

You will find out that the C5/C6/C7 cars DO NOT tolerate having a battery that is NOT fully ready to support the electrical system.

Learn to READ the cars Diagnostic Trouble Codes (DTCs) using the DIC! It is your MAIN defense against spending LOTS of needless cash!

Plugs and Plug Wires. Don't know what it has but if they are not recent, Get the GM Performance RED wires and some new AC Delco Iridium plugs.

Check the PCV Pluming for rot and the vacuum lines for rot and cracks.

READING YOUR Engine Diagnostic Codes



The Diagnostic Display Mode is entered with the following procedure:

1) Turn on the ignition but don't start the engine. NOTE! You can read the DTCs with the engine running and or driving down the road but it can distract you. BE careful! Some DTCs clear themselves when you turn the ignition OFF!

2) Press the RESET button to turn off any warning messages. (i.e. door open, trunk open ect)
3) Press and hold OPTIONS
4) While holding OPTIONS, press FUEL four times within a 10-second period.


Initially, on-board diagnostics go into an Automatic Mode which shows diagnostic codes in a pre-set sequence: PCM - TCS - RTD - BCM - IPC - RADIO - HVAC - LDCM - RDCM - SCM - RFA. All codes will be displayed for each. ( i.e. PCM = 4 codes) If none are present in a given module, you will see No More Codes on the display.
There are two kinds of diagnostic codes, Current and History designated with a letter suffix, “C” or “H”. A current C code indicates a malfunction is present and active in the module displaying data. A history code indicates a problem existed sometime in the last 40 or 50 ignition cycles. When not accompanied by a current code of the same number, it's potential evidence of a previous problem, now resolved, that was not removed by clearing the codes.
More likely it's an indication of an intermittent malfunction.
Intermittent codes are the most challenging of the diagnostics. An intermittent code may have happened once, may have happened more than once but is inconsistent or may be happening on a regular basis but not at the time the codes are displayed. History codes can also be caused by a current malfunction in a system that is not operating at the time codes are displayed. An example is the rear window defogger which doesn't operate until the Body Control Module detects engine rpm. For history codes set by a module that does not operate with the key on and engine off, a special diagnostic tool called a Scan Tester is necessary to properly diagnose the malfunction.
Once the system has displayed all modules, it goes into the manual mode which allows selection of each module using combinations of Driver Information Center buttons. Manual mode can also be entered during the automatic sequence by pressing any button except English/Metric (E/M). Once the display shows Manual Diagnostics, select a module by pressing the OPTIONS button to go forward or the TRIP button to go back. Once a module is selected, a code is displayed, and if more than one are present; press GAGES to go forward or FUEL to go back.
To exit the diagnostic mode at any time, press E/M. If you want to erase codes in a given module, press and hold the RESET button To reset the codes once in manual mode, press and hold RESET until it displays NO CODES Press OPTIONS to go to the next module. Repeat the steps until you have reset the codes in all the computer modules.
NOTE!! Only reset the codes IF you want to - it is NOT necessary to do this. Clearing a code does not repair a problem. You are simply erasing the evidence of it in the module's memory. If you clear the code/s, and extinguish the Check Engine Light, your emissions status ready will NOT allow you to pass an emissions test until you have completed the required driving cycles.
Once you have the codes, the next question is: What to do with the information?
First, consult the factory service manual. Any serious C5 Do-It-Yourself owner should invest in the Corvette Service Manual of the appropriate model year. The Service Manual is really a requirement if you want to understand and work on your C5. You can GOOGLE the DTC and also find information on it.




Here is very good site that explains the DTCs:

Make sure to include the H or C suffix!!

Vetteman Jack

All the above is very good advice. Another thing I might add is to check the belts and hoses and make sure they are in good condition. Best of luck with your C5.

He wrote that it's an FRC.
I'd be surprised if it wasn't a manual. <g>

Ya rotors are vibration-y so I'll definitely be doing a full brake job. Okay I'll the fluids all around too with the other items.

Thanks I looked through those when I first got here but now that I'm actually getting one I need to read again.

Forgetful

Thanks I need to check that battery for sure, I suspect it's toast given it wasn't used much. Couple things currently wrong with it I'm hoping battery might fix.

Things I know I need to fix are:
Windows don't go down,
Vacuum line for AC vent control broken,
Oil pressure sender],
parking brake loose,
headlight gear close to stripped
Traction control light on (bad EBCM or who knows, need to check codes)
