Every C5 Corvette Owner Needs To Watch This!

[@charliedee9276]

I recently had a C5 given to me by my parents, a 2000 with 110000 miles on it. No leaky battery but it was replaced immediately with an Optima, which was convenient because the battery that was in it fit perfectly into my Jeep. I also immediately treated it with Techtron, the idle improved right away.

And keep an eye on the harmonic balancer and tensioner pulleys...

[@John-ip3xm]

Frank, good point...the C5 and C6 have an inherent problem with wobble on the harmonic balancer, if left neglected, can slide forward into the power steering unit or backwards into the oil pan. A poor design by Chevy!

[@mran6011]

Great advice....If you still use lead acid batteries, please be sure to use an acid neutralizing battery mat underneath it. Simply, cut to fit. They are super absorbent and will neutralize any acid that comes in contact with it.

My fuel Guage is was sticking intermittently, I was told by a guy at a car show to try techron.. I ran the tank to about an 1/8th , poured in a bottle of techron & 10 gallons of high Octane gas. Problem had gone away and never came back. I do another treatment at the same time I change my oil

[@paulstoolbox]

Great information, thanks!

[@stephendibari5010]

Excellent video!

[@davidterceira7451]

Hey Jim, Thank you very much. From a guy that makes a living fixing broken corvettes. Giving that advice is very noble. Have a great day!!

[@Nick_69srt]

Do C5s commonly burn oil ?

[@michaeldao9897]

Thank you so much Not all heroes wear capes!

[@LHG86]

Great straight forward truthful info, thank you.

[@JWJYT]

It's my pleasure!

[@MCGDEC]

techtron and top tier gas.

[@mwp1088]

Costco is always top tier gas as well!

[@MC-uj4co]

Some clean true advice 👌 safe travels. I run Lucas fuel treatment lubes and keeps the injection 💉 clean

[@bobbytalbot4803]

Thank You for the heads up. Techtron every 2,000 miles & fresh battery every 3yrs to 4yrs tops

[@markwarren7959]

As soon as I got my 2001 Vette' I put an acid absorbing mat below the battery. It's wider and longer than the battery so if anything oozes out of it, the mat will catch it. I also went and changed the harmonic balancer from Summit Racing. Didn't need to but did it for assurance.

[@mokeozinga7290]

I've been running the marvel oil in my C5 tank at every fill up. I've heard good things about it, so I started putting it in all of our vehicles ('97 Vette, '07 Silverado, '16 Crosstrek) and I even noticed a smoother idle in the Subaru. Have yet to add it to oil during changes.

[@craigthescott5074]

That’s why you use a dry cell battery’s they cost more but they last longer and make more power. They also don’t leak acid all over your computer that sits below your battery. They also don’t drop cells on a stiff suspension vehicle like and acid battery’s do. I had a dry cell last 13 years in a C2 that I didn’t drive much but was hooked up to a trickle charger. No lead acid battery will last that long.

[@danmonical5756]

Add replacing factory valve springs with aftermarket heavy duty valve springs, it could save you from having to replacing an engine. Factory valve springs are weak and can break at anytime with normal driving.

[@genej501]

Don't know whether it means anything. But I use Chevron premium all the time.

[@coop4274]

Actually the battery in the c5 is supposedly to be an agm battery anyway not a lead acid.

[@etharp40]

Good info to employ

[@kevinbryant6459]

Wow thank you for the video i will really keep my eyes out and maintain my battery

[@radioflitercairplanes1715]

Sealed battery PERIOD. lead acid is to risky , if it leaks for whatever reason , it can leak down under battery and if it gets to the ECM..well have fun with that. Run a sealed battery like the Red top Optima..a little bit more expensive , but worth the money. A duralast led/acid battery at Autozone for my C5 was $149.99 The Optima was $199.00 dropped at my shop door. No brainer.

[@craigthescott5074]

100% agree.

[@genej501]

I run Chevron premium with tectron for gas in my vette

[@oscarfuentes280]

Thanks for the advice

[@ant9223]

very good

[@Gr8erh8er]

I have a C5. Replaced my fuel pump at 64k miles. Not that hard to change just need to know the rivets are threaded. Knock the heads off and unscrew the studs. Biggest cost is replacing the clutch

[@roybishop6110]

Run Sunoco 93 octane no worries

[@dhj.feb7953]

Short and to the point 👉

[@geneknight5194]

Clean the udders

[@jeffreyneedam8161]

are you in delaware?

[@TheMjphoto45]

I had HB upgraded

[@raymondshartrand40]

HB UPGRADED? 🤔

[@TheMjphoto45]

Yes. Summit Racing

[@paulmaher3358]

Don't forget to clean the utters under the wiper motor.If they get loaded with leaves ECT and can't drain the wiper motor gets flooded with water and short's out.I learned the hard way.
