Changing fluids that were never driven with?

Its now been 2 years since I assembled the drive train and took the car to the paint shop. Wow how time flies.

So I was thinking I should change the oil (after I'm done setting it up/tuning), but am also wondering about antifreeze. Although the car wasn't driven, the rust inhibitors may be used up. As I get ready to drive the car, should I change out the coolant now too?

Brake fluid is Dot 5 and I'm still fighting a couple leaks with the stainless lines, so that will be cycled out by the time I'm done.

Trans and PS fluid was just put in a couple months ago so no worries there.

Rear axle fluid is 2 years old but again, not driven on. I'm leaning against changing that out.
 
I agree. I'd and change the oil and engine coolant, but I wouldn't bother messing with the other fluids.

I don't remember if your ride has a freshly rebuilt engine or not, but are you running a filter (Gano or Tefba filter) on your engine coolant system?
 
No, I'm not. But I just looked up the tefba and I like it. I'll add that to the to-do list. Although I just read some topics from VMF that the tefba was cheaper than the gano and so far I'm only seeing it on ebay for roughly $70. Is that ballpark?

Sam,

Save yourself a few dollars and leave the existing oil/coolant until after you've driven for a few hundred miles. With the car fresh from a ground-up rebuild you're likely to have minor issues to work out during the first few hundred miles. Some of these issues may involve draining the oil/coolant. If 500 miles comes and goes without issue then you can change out these fluids. You'll do no harm to the engine during these first few hundred miles with the existing fluids. Remember that you're going to have to be taking it easy as you break-in the clutch and rebuilt engine.

Good point, will do.

Gee, thanks. I was going to order one today right now, but I can wait until I get home to use one of those thingamabob's you pictured.

Ah, I'm sorry. I thought you were still laying around on the couch.
 
LOL, no worries.

I went to see a doctor yesterday, and he fixed me right up in about 2 minutes with some pushing and pulling. Not in a gay way.
