Hey guys, I've got 59400 miles on the Z. I know the powertrain warranty is up at 60K so I wanted to give the Z a checkup to make sure everything is on the up and up. I also wanted to get some basic maintenance done. Here's what I wanted to get done:

1. Plugs pulled, checked, and cleaned if necessary.
2. Compression test
3. Leak down test
4. Coolant drained, flushed, and refilled


Now on to my ?'s
1. Is there anything else that I might be missing?
2. If they find anything wrong with the engine, it should be replaced correct? For example, if they do the leak down test and find something wrong, will that be fixed free of charge?
3. Lastly, I was glancing over the warranty manual and it said that a record of all maintenance should've been kept or the warranty work might be denied. I've been changing my own oil since I bought the car new but I haven't kept any records or anything. Will I run into any problems?

 

Looks good to me. When was the brake fluid replaced?

 

It hasn't, is that something that needs to be done regularly as well? If it is I'll probably do it myself when I change my brake pads. Which will probably be soon.

 

Yes! Since brake fluid is hydroscopic, old fluid can lead to corrosion of brake system components. In a more extreme example, enough water content will effectively lower it's boiling point. If the fluid were to boil (during hard driving/racing), you could experience a dramatic or complete loss of pressure. It should definitely be replaced periodically (every 2-3 years I believe).
