The latch springs work, but they are 'tired'. At first glance, the job looks very simple. All my searches reveal that the spring is not easily removed.
Many, if not all, have removed the spring bracket for access to the spring unit which creates a re-install alignment concern. I have springs on order ($16), but unless someone has successfully replaced the springs without removing the brackets, I think the springs will remain in the shipping box. The hood on the Andy Bogus vette probably has been released more times than any other. How are your latch springs working, Andy? |

Are you sure they don't just need adjustment vs replacement?

Matthew, the springs release the hood from the latch sufficiently to lift to the upright position. They are 20 years old, and the release action is more like a weak push rather than a pop up. No adjustment is evident as it appears that the springs are just secured in the assembly, and the rubber bumpers positioned on the bracket provide the hood adjustment. |

Is your hood lifting up enough to clear the latch pin when released? If not then it's possible the latch pin needs adjusting for/aft or cross car.
The primary purpose of the springs is to pop the hood up high enough for the "pecker pin" to clear the "fish mouth". After that the hood struts do the work. On my 89 I had the primary rod on the drivers side, plus the short helper rod on the passenger side and it would jump up so fast that I removed the short one. Might want to try a short one in conjuction with primary, I assume yours will have the mounting plates? Joel |

Joel, the springs are performing OK. They are just very old, and the replacement of the springs should be quite simple. Unfortunately, I have not read a thread confirming the simplicity of replacement. It appears there is a locking nut at the base of the assembly, and the shaft has a slot for assembly adjustment, but the components are 'frozen', making removal seemingly impossible without breaking something. On the '92, there is only one support/lift strut, and you have to initiate the lift, and then the strut provides lift help. I can live with the existing situation..... 'tired' springs on the vette, and replacement springs in the shipping box. |

Yea, I understand. Sometimes it's best to leave well enough alone, at least with me!

FSM: "Loosen jamb nut". The jamb nut is very thin (about 3/16") ..... no way to get a 'bite', and I'm very concerned about removing the bracket plate without causing damage to the hood. The jamb nut is about 1 1/2" wide..... looks like a closed-end thin bicycle type wrench could be slipped over the spring assembly onto the nut. If the wrench was secure, it might be receptive to a few hammer blows to break the jamb nut loose....... not sure. |

The latch springs... hm... they get sticky, from my observation.
I will clean mine up, and the releases, with brake cleaner, then slather on a coat of anti-seize. Seems to help for quite a while. As for replacing the springs... yea, take the plates off, make sure you mark the bolts with a paint pen so you can line everything back up! Remember, that bolt is under spring tension, and has been exposed to the elements for 20 years. You may also want to spray that area down with PB Blaster to free things up. |

Thanks, Andy...... have done all the cleaning and lubrication work.
The springs power the hood from the latched position. That is their sole purpose. As I mentioned in my first post, they are just 'tired'. Replacement is a snap..... loosen the jamb nut, remove the shaft using a screwdriver in the slotted end, and replace the spring..... except every fastener is 'frozen' after 20 years. The mounting plate/bracket should not have to be removed, only the jamb nut should be loosened..... in theory. I was just hoping someone had experienced the process ....... the replacement springs will remain in the shipping box for the next owner. Thanks to all for your replies. |

In addition to the single factory strut I installed a pair of earlier C4 style struts on my 94 and the hood now lifts like a feather.
 Picked up the Sachs SG430011 struts off ebay for $8.53 ea. http://www.ebay.com/itm/120933386149? ... _trksid=p3984.m1497.l2649 |
