Default Reliability Suggestions

Just finished doing a bit of a roadtrip in my '69, which I only got in November so it's pretty new to me, and it did the trip okay but it got me thinking about what I need to do to make it more reliable for longer trips. Or at least more trustworthy. It's a 427 4-speed.

Anyone have some suggestions on items to look at or upgrades to make?

I think about the only things you can do economically (and rationally) is to go through the regular maintenance items. Change out all fluids, belts, and rubber brake hoses for which you have no evidence of being done in the last few years; lube all grease fittings and inspect the rubber boots; inspect brake pads, coolant hoses, and tires (for age and unusual wear pattern indicating worn/misaligned parts). That's about all that could leave you stranded other than catastrophic failure of the engine, trans, or rear.

Make sure tires, battery, cooling system are up to snuff; change oil, filter, and top-off fluids; make sure your insurance is paid up; make sure you take credit card and cell phone.

I think tha's about it............

Not a reliability thing, but something everyone should have behind the seats.
A fire extinguisher.
I've never needed mine, but it's nice to know it's there.....

Check all electrical connections under the hood and make sure all ends are properly terminated, shrink wrapped and clean.
Take a good look at your fuel line and make as much of it steel line as possible.......
Make sure your cooling system has only distilled water and some anti-freeze in it......no tap water ever.
Lots of other things but it boils down to attention to detail.....

Besides some of the items mentioned already, not knowing anything about your car and what has been done or not done, I have a few more things:

Change or have rebuilt the alternator and starter motor.

Carry a new ignition coil and points with you as well as condenser

Considering having the rear trailing arms rebuilt with new bushings ( not critical to breaking down) and especially new rear wheel bearings (critical).

All U joints replaced-Half Shafts/Driveshaft

Carry a new AC delco fuel pump in the car so if it fails you or someone else can easily replace the bad one.

Fuses to replace one if it blows, accidentally.

Plug in air compressor for air if you get a nail and need to drive a moderate distance to change or repair.

Spare belts for the engine.

Comprehensive tool kit for emergency repairs

Lots here but if you do half of them, you will be way ahead of most C3 owners....

My Dad used to keep a spare fuel pump and points/condenser in the glove box of his 66' Vert when I was a teen.........it proved fruitful when he made a trip to St. Ignace Michigan in 1990 and the fuel pump quit 250 miles from home........I changed it for him in 45 minutes and back on the road......bad ***. I would have been 19 LOL!.

That's why we have 'roadside assistance' with our collector car insurance and carry the cell phone.....

Tune up
fluid change including radiator flush
check all your joints and tie rod ends and lube whatever has a zirq fitting except your power steering control valve if it has one
check tire dates for age And pressures
check your lug nuts
if you don’t like how your brakes are performing upgrade your pads to ceramic pads
Up grade your headlights to a h4 lense and a brighter bulb or LEDs so you can see at night

you can swap to a HEI system if you want to or convert your points system to a point less system. I used the one from Lectric Limited and I never had an issue with it.

i upgraded to a 5 speed and its one of the best upgrades you can do.

Completely agree with other suggestions for basic maintenance, but the biggest thing is to drive it...a lot. Driving it does two things: shines a spotlight on any issues that do exist and builds trust with every successful drive.

Agree with all the above. For long trips I carry spare belt(s) and always a spare set of tools.

In my case, I had no issues on this last trip. I'm just a Ford guy and this is my first Chevy in 20 years and it's a little on the bubba'ed side (ie. the well lights stay on and drain the battery, the wiper plate fell out and had to be held in place) so I'm not super familiar with all its quirks as yet. Also, on the drive home with it, the wheel bearing welded itself to the spindle on the driver side (hard to hear over the side pipes and highway), and the fan lost a blade making it unbalanced, so twice bitten twice shy. I just want to make sure I get all the major stuff out of the way so I'm not sweating bullets for 2-plus hour drives.

I wish I could road trip in my '73 and be guaranteed to have cell phone service. Unfortunately, that ain't happening in my neck of the woods no matter what the service maps show.

When you get into a "non-coverage" area and have an emergency, dial 112. That is a worldwide emergency number that sends signal to the nearest point of reception (not just cell towers), and it will be relayed to the nearest emergency (911) site.

Ditto on electrical connectors. I've been testing and performing failure analysis and reliability analyses on them for over 30 years. Most failures are inconvenient, a light out kind of thing, but some will shut you down. I had this occur on my 80. The ignition lead in the large connector with that and about 5 other circuits failed. Unmating and remating cured it temporarily. All the contacts were unplated brass which are susceptible to something known as fretting corrosion. The connector housing was partially melted due to the increased resistance from the corrosion causing the contact to run hot. I replaced all the contacts in that connector with tin plated types - also susceptible to fretting corrosion but will last longer than brass given some other factors.

When looking at the connectors look for evidence of overheating and brittle insulation leads and housings. Replace as necessary. I will say that on my 80 I am surprised at how good most of the wiring and connections still are.
