Default Fun Project Day Tomorrow

Well a cracked radiator has propelled the project day. I've had a few things needing attention, parts ready, and just no time or place, as I live in an apartment. But, the radiator is something I need to make time for. I have a friend that has kindly donated his driveway so it's the day.

On the list:

As the engine cools, rotors and brake pads all the way around.
Clutch slave cylinder
Spark plugs
Brand spanking new AC/Delco radiator

I probably won't get an answer to this question at this last minute, but you never know who's on...On the rear brakes, is there any trick or complication to removing the caliper braket? Or is it pretty straight forward like the fronts?

I don't do the rear in the way the FSM regarding the parking brake. The only thing I do is take the parking brake (arm w/cable attached) off the caliper.

Chris, this assumes your LT4 is the same as our L98s. I was surprised they don't need the special tool to rotate the piston back in either.

If the 96's need that, I have a set you can borrow.

Default Wow...just wow.

So the morning started off cold and drizzly. My first project was the slave. My lovely car rewards me by spitting hyd. fluid all over me. But I knew that was going to happen. But it just didn't want to go in for a long time, but it got done...(I hope)

Then brakes, this went pretty well, pretty smooth. Fortunately it had warmed up a bit so I didn't have to go in and warm up every 15 min. But I only got the fronts in as it was getting late.

Anyone know any tricks to getting the six little bolts that hold the lower and upper shroud together. This was the deal breaker for the radiator today as I didn't have any way of getting those. I really would like to not discharge the a/c if I can help it. They appear to be 7 mm, does that seem right. I think I could get the lower two with a socket and extension, (which of course, is the one I don't have) it's the top one by the hood hinge the seems to require patience (which I don't have).

And I believe the parking brake cable will come off pretty easily, as least as I've seen it done.

Oh, BTW, now I know why mechanics like to charge the "Corvette Tax". So many bolts and screws, so many different sizes, standard and metric. Does GM hold stock in MAC Tools or something?

The shroud is held on by a few 10mm head bolts and a slew of 7mm head bolts. A 1/4" air ratchet makes for quick removal. The ac doesn't have to be bled or removed.

On the drivers side, you have to move some stuff out of the way to get at the three small screws. It was a PITA, and if you've got really big hands, that would make it even tougher. On reassembly, I only replaced two of the srews on each side.

Once you have the fasteners out, it takes a bit of fanagling to actually pull the shroud off, but it does come eventually with patience. You don't need to remove any A/C or cooler lines to do it. When you put the new rad in, make sure the rubber pads are in the right place, otherwise the shround won't go back on.

Since the assembly was put in complete, those 6 screws (aside from heater core) are probably the most rediculous to remove.

Once removed, reverse the speed nuts to the top part and insert the screws through the front of the car (air dam opening). You will never sweat it again.

My thoughts exactly. I'll just have to allow a little more time than I first expected, get a longer wrench and a wratcheting driver. My major problem on Wed. was that I didn't save enough time and it was getting dark and the cold front was coming in. It went from 50* to below 30* in about an hour.
