Need a checklist
Going to look at a low mileage ZR1 next weekend and I could use a checklist of sorts as to what to look for.
I know to ask about Fuel Injectors, Fuel pumps, Secondaries, air conditioner. Any other areas of concern I should be looking for? Thanks. |

Re: Need a checklist
Did this a while back over on the other forum.
That all depends on what it is that you are looking for. If you don't work on your own cars and you want a fun weekend car that is reasonably reliable you will need a car that has been upgraded with at least some of the major known ZR-1 and C4 issue already addressed. If your like me you enjoy wrenching on the car and the challenge of fixing everything. I look for a solid car at a bargain price and do the work myself. To me that's a fun weekend. I'm sure I missed few but here you go. Known major issues ZR-1 some related to higher miles some not. Injectors have they been replaced Vacuum leaks Secondaries operable, do you get full LT5 power Ingnition coils and wires replaced Timing chain noise (normal to a small degree on 90's) Starter Oil leaks especially the pan and oil cooler lines Does the engine smoke or burn oil (normal to a small degree at startup on 90's) Fuel pumps have they been replaced Is it throwing any engine, abs or body codes (multiple possibilities here) Are any DIC lights on. (Multiple possibilities here as well) Is the adjustable shocks system working Windshield delamination A/C functionality (compressor is unique to the Z, cooling capacity lower) Power switch functionality and keys (are there 2) Transmission syncro's, (first gear is always noisy) shifter alignment can mimick synco problems. Clutch functionality (they all let in high, was it ever changed) Egr system on later models Engine mounts C4 Issues Head lights operable Radiator blocked or simply clogged, electric fans operable Wheel bearings Suspension bushings Condition of all door, top and hatch seals Glass roof cracking Instrument cluster functionality especially the tach (tends to read high with age) also note the lighting of the cluster. DIC button functionality Steering wheel excessive movement Radio functionality (especially speaker amps) and antenna Sport seat functionality (transmission, switches, pumps and bladders) Door window switches Door window lifter and internal rattles Fuel tank bladder collapse (results in small capacity) Differential noise (whine) Have fun...

What he said...…………… He gave you an experienced owner list! I will only amplify the fuel pump issue. Most all cars that have not been regularly driven have pumps with rusted or at least rusting frames. If so, you need to drain and thoroughly clean the tank and lines, and of course replace the filter and tank strainers. But back to the list. This is why many folks correctly suggest buying a sorted out car even at a premium, as it is likely far less expensive than correcting the many things that are often found operating below optimum. Best of luck, and keep us posted! (to ccmano) GREAT list!! Marty |

Re: Need a checklist
Here's a link to the checklist on ZR1.net.
http://www.zr1netregistry.com/Market...yersGuide.aspx Don't know if anything there that ccmano didn't list, but might be a good cross reference. Good Luck!!

Re: Need a checklist
Congratulations in advance for getting a ZR-1. (If not this one, another).
Be sure and join the ZR-1 Registry if you have not alredy. As you do your work yourself you will be leaning on the members a lot. Very knowledgeble members in every area of these cars. Also, be sure you have a FSM for the particular year of your car.
