1992 Upper Radiator Shroud Removal

[chesnut]

Help with upper radiator shroud remova;
- all fasteners removed - see attached screenshot

Upper radiator shroud seems stuck to radiator.
When I pry up on driver's side flange with some force, the shroud will raise 1/2 inch, but that's it.

Did I miss some fasteners or ?

Thanks in advance,

Gary

Did you get the 3 on each side? 8mm head.
Also 2 on each side down by the frame rails.

Subfixer,

Thanks for info.

Just found the drawing that shows 3 on each side - see screenshot.

Question - how in the heck do you get to those? Do you have to take the air pump off on the driver's side?

Thanks,

Gary

[Subfixer]

Yes. I had to remove the air pump to get to mine

Subfixer,

Any secret steps/processes to removing the air pump?

Don't have a lift, so I'll have to jack it up and use a jack stand.

Thanks,

If I remember correctly, it was just a couple of bolts. I disconnected everything from the top. Remove the hoses from the pump. It doesn't need to move far.

Subfixer,

Thanks. Will give it a go.

Subfixer,

How did you go about getting the 3 8mm screws/bolts out on the passenger side?

Did you use a flexible long extension or ?

Those screws/bolts are very akward for this old man to get to.

Your help is much appreciated. Thanks,

Gary

[Subfixer]

Yes. Very hard to get them. I used a small 8mm wrench for the ones I couldn't get with a 1/4 " drive ratchet, extension and universal joint.

Once all the bolts are out, the next challenge will be getting it out from under the AC and oil cooler lines.

Subfixer,

Thanks.

Am thinking about sitting on the floor with my feet under the car and reaching in to remove those 3 8MM screw/bolts. Rather than bending on my knees.

Curious what position you used?

Thanks,

Gary
....

[Subfixer]

Did all from topside.

Subfixer,

On your knees or sitting with feet under?

No matter how you approach the 3 screws on each side, it's
a PITA!
My advice, be patient....
OBTW: Subfixer has a lift 😀. but still a PITA

[chesnut]

Mystic ZR1,

Thanks. Patience is not my virtue. LOL

Had lifts until I downsized and now I don't. :(

Doing the pass side is my Monday project.

Chestnut, are you any relation to Joey Chesnut the hot dog eating champion?
😀

[chesnut]

No, not directly, but was once told we're all distant relations.

Subfixer & Mystic ZR-1,

Was able to bend over and remove 4 of the 7MM screws (2 each side).

Ordered a flex head ratcher wrench to remove the top 7mm screw on each side.

Waiting on new the new wrench to remove the last 2 - 7mm screws. Ordered a DeWitts 2 row pro radiator.

BTW DeWitts gives 10% discount if you're a Veteran.

[Mystic ZR-1]

Good choice on the radiator!

[chesnut]

Mystic ZR-1,

Thanks. Have used DeWitts several times in other Corvettes with good results.

Question - has anyone used Marc's 170 degree thermostat? Would like to know if it helps when driving in high Texas summer heat stop'n'go traffic.

OK guys, have all the bolts/nuts/screws out of the radiator shroud.

Driver's side up in the air approx 25 degrees. Pass side - unable to get passed the A/C lines, especially the lowest one.

What's the trick to get the right side of the upper shroud out?

Thanks,

Gary
....

[Subfixer]

For me, it was a lot of trial & error, just hoping I wouldn't break anything. However you get it out, remember because it goes back the same way.

Subfixer,

Got'er out. Had to trim a tad bit more off of the pass side shroud mount and slightly use a prybar to get around the lower A/C hose.

Radiator had some debris on it, but not bad.

Appreciate your help and guidance. Thanks,

Gary

Guys,

Am having a hard time getting the upper shroud reinstalled.

Problem is getting passed the small radiator outlet hose on the upper RH side of the new DeWitts 2 row radiator. The outlet is stuck against shroud back on the housing.

Have the upper radiator shroud at 90 degrees and the lower end of the RH shroud flange almost to the bottom hose.

Appreciate y'all's input on how to get the RH side of the shroud in place.

Thanks,

Gary
....

Any ideas.

[chesnut]

Guys,

Gave the upper shroud another try. Some whamming and pushing and the shrouds down over the radiator.

Appreciate everybody's support. Now to button it all up.

Gary

[Subfixer]

I don't remember how I did it since it was several years ago. Probably the same way you managed it. Getting the spacers in will be another challenge.

SubFixer,

Took at least 6 to 8 tries to get the upper radiator shroud in. Would try every 20 minutes or so. Twisting and banging. Finally got it passed the small upper radiator inlet and then it fell right into place.

Just finished aligning the nose and getting the easy 4 of the 7mm flat head screws in. Was able to use a long 7mm socket screwdriver to remove and reinstall those screws.

Will use a 7mm swivel ratchet wrench to install the top 2 flat head screws. Use blue painters tape to jam and hold the screw heads into the wrench head.

If you're referring to the 1/4 inch radiator spacers? Already have the bottom installed. Had to get long screws. Clamped the fan housing down with vice grips and just couldn't get the 10mm screws to start.

Thanks,

Gary

Help, how do I get the electric air pump 2 inch air input hose to stay on the air pump when I tighten the clamp?

Seat the rubber hose & block it with a piece of wood.

When I tighten the clamp, the hose starts sliding off.

Only thing I can think of right now is using RTV.

Thanks,

Gary

[Subfixer]

I didn't have an issue with mine. Make sure the intake assembly is in the correct orientation. Hose should just slip on.

[chesnut]

Subfixer,

That's what's totally weird - the pump is bolted into position. Pump and hose match orientation in the pre-removal photo I took.

Hose does slip on - hose starts sliding off as clamp is tightened.

As Mystic said "patience" is not my virture. :)

Thanks,

Gary

1st try this morning and the hose stays on the air pump input when clamp tightened.

Go figure.

Next step is installing the Heibeck Throttle Body Heat Bypass tube.
