I like the honesty in your videos. You don't pretend to know everything like some others. Good job and keep em' coming!

[@mycorvettelife]

Thanks

[@larrybledsoe4760]

I hope you stay at it Chris! It's too easy for others to take cheap shots that reflect their own flaws. I've only recently found your channel and feel I've definitely learned from same. I can appreciate the time and expense (let alone frustration) you are experiencing. My Navy Blue 2000 (11,400 miles) retirement present to myself is awaiting the V-ramb2 and aftermarket exhaust coming up this summer. Your trials and insights inspire me.

[@mycorvettelife]

Thanks! Put some miles on that car!

[@myfastcars]

NEVER EVER use a plastic fitting in the cooling system They can get brittle and crack/break causing loss of coolant. Use brass or SS fittings. The one piece hose is a much better solution.

[@kevinbatts2804]

Hey Chris, I finally got my first Corvette last night. The car is a 2005 Base model precision red with 100k miles. Thanks for all the videos it definitely gave me a honest look at Corvette ownership.

[@mycorvettelife]

Thank you, and congrats!

[@jeffb243]

I have the same Vararam intake you have. I just bought my 1st Vette, a Torch Red 2001. Looking forward to learning all I can about these cars. You’re helping quite a bit with your videos!!

[@eddiesimpson156]

Had seen this video a while back. I changed the all hoses on my c5 to silicone. After watching how clearly you showed the bypass and cleaning throttle body and mass air flow sensor I also did that as well. Thanks for the video.

[@jeffb243]

Learning a lot from you Chris. This being my first Vette, I have few things to learn about Corvette’s. I’m going to be cleaning my throttle body and my MAF hopefully this weekend. Pretty crappy weather here in TN lately. Having had a 2006 GTO with the LS2, I know some of these things you’re doing to your Corvette.

[@vernoneshelman6829]

Enjoying the videos chris I just purchased 99 c5 Vette my first

[@buickmonte]

Great job bro,add this to my to do list for my vette.

[@Digable.]

I feel like your channel just keeps on getting better with time, keep up the great work! You even inspire me to work on my rides!

[@mycorvettelife]

I really appreciate that. It’s been tough to get motivated lately. Views are WAY down.

[@lionelruningen6087]

My Corvette Life Hang in there Chris. Love your videos!! I am proud owner of 2009 Convertible with 11k miles. LLR Castle Rock Colorado.

[@Kizaboy8]

Awesome video bro! Great job

[@Patrick8200]

Just an FYI, the purpose of the coolant flow to the TB is to prevent throttle freeze-up due to water vapor from EGR gases.

[@awittypilot8961]

Sorry patrick...that's not true...it is to heat the throttle body to meet emissions.....if you bypass it you may gain a bit of power because the entering air will be slightly more dense....

[@jessies1509]

@@awittypilot8961 Where did you get that info from? Only asking because I’m not sure who to believe lol. If I do the bypass, I want to make sure it’s actually going to be beneficial.

[@awittypilot8961]

@@jessies1509 Believe it or not, the air going through the EGR is considered "cool air" because it cannot combust. If you don't do the entire delete and get rid of DEF you probably won't see much if any gains.

[@jessies1509]

@@awittypilot8961 Thank you! That’a exactly what I wanted to know. I just got done cleaning my throttle body and didn’t do the coolant bypass.

[@Emerging_Judean_King]

Awesome video! I'm gonna get on this tomorrow. Hopefully that hose won't be an issue.

Glad you enjoy it!

[@1wtrahan]

When you said now it’s ready for a cold Start ,I was thinking a cold beer ha ha good job I need to do that gotta get that bottom cooling hose though before . Thanks Chris

[@youngestson6537]

Man. That thing is cleaner than it was from the factory. 👍🏾👍🏾

[@turbobrian]

Coolant goes through the throttle body to help warm the engine, and is basically for emissions purposes, so unless you live in an area that frequently freezes up, just by-pass the coolant throttle body runs.

[@mezzyshredder]

Coolant through the throttle body is simply to keep the throttle body warm during cold weather.Thats why Toyota does the same thing. Hope this helps.

[@stanleykee]

very good job cleaning your TB

[@Kixortiz_]

Thanx man! Good one.

[@georgecolahan130]

Great vid , as usual, could you tell me what you used for polishing like FLITZ etc. thanks

[@vincebermudez869]

Thank you for the video. I purchased my 2000 Corvette with 118,000 miles in December for $4500.00 and I love it. Keep the videos coming.

[@mycorvettelife]

That’s incredible!

[@randy2.0kitt]

How? Doubt it crashed

[@vincebermudez869]

@@randy2.0kitt I have no reason to lie. I worked for an auto parts store and i sold automotive paint. One of my paint customers had it, it wasn't been driven so he put it for sale. He originally wanted $9000.00 when he started trying to sell it. He desperately needed the money for taxes and as time went on he wasn't able to sell it so he kept lowering the price. When i bought it the car was missing the acrylic top but the frame was still there so it caused a terrible turbulence so i offered him $4500.00 instead of the $5000.00 because it shook so bad. He drove it himself and as mad as he was he let it go for that amount. The car isn't perfect but it is in real good condition. I live in texas, if you want it, i will sell it to you for $6500.00. I will send you pics if you want just give me an email address.

[@ColdVsIce]

@@vincebermudez869 I bought mine for $3500 in perfect condition. 90k miles

[@papagigo1]

Good job explaining everything . What about the 2 hole left on the throttle body, just leave them as is ?

[@MyVetteLife]

Thats a fantastic shot @ 1:05

[@ss-5553]

Nice video thank's !

[@scubasteve31583]

My 03' C5 has 8 mm bolts for the side terminals to the battery. I always keep an 8 mm gear wrench in the car so I can change the battery out if the electrical gremlins pop up from not driving it for long periods of time.

[@ecapone9223]

More power to you. I’m nervous to do it

[@dominickirkwood]

Very good

[@HipsterDoofus100]

I disconnected my battery for the winter and my mechanic told me it was a 10mm. When I’m reality it was an 8mm like yours

[@pjbrien3276]

what did you use to block off the valves on the manifold?

[@Kamken81]

nice job

Great video Chris thanks, think I will bypass the coolant line as well. :)

[@larrylentz2592]

Good job

[@mycorvettelife]

Thanks

[@lionelruningen6087]

Chris great vids! Have you had any mechanical training? You seem very knowledgeable about Vette mechanics.

[@mycorvettelife]

All self taught.

[@cauldec]

What were the attachments that you used for the clean and polish on throttle body? The wire wheel is obvious but I saw three different attachments and tools to do it.

[@mycorvettelife]

Wire wheel, medium grit fiber disk, and buffing wheel.

[@dwg1235]

Amazing video, for future, pull the throttle body away from the tube, always pull bigger item for leverage. Pull ing tube off is impossible if it's corroded but it's easy if you pull, twist, yank throttle body, lol

[@pjbrien3276]

Nice Vid but I am curious were did you purchase the car seats (CORBEAU) thinking about switching out my old seats.

[@mycorvettelife]

Direct from Corbeau

[@GregorioLonewolf]

Just got around to this video Chris and I know it's from 4 years ago. But my battery terminals are also 8mm not 10mm???? Go figure. Coolant going thru the throttle body as you did say is for cold weather locations. This is 2022 and believe me most of us have been freezing as I was in the mid teens here. Bypassing the throttle body will give you cooler air passing thru giving some power gain but not really noticeable when driving. Unless you do more engine mods as you have. Good video btw.

[@ivanecheverria9892]

Chris You are brave to do this job in summer, 108 man! I am in Phoenix too and too hot in my garage. I have a question, I have a C5 02’. Since we can’t get gas higher than 91, do a lot of folks use octane boost(104+)? I am getting some noticeable pinging. Does anyone else out there experience this with C5s? My plugs are new and engine only has 46k. The octane boost helps but does not get rid of it.

[@mycorvettelife]

Is your motor stock? 91 should be fine. You can try octane booster to see if that helps, but it sounds like a different issue. Have you had your valve springs checked?

[@donaldmiller3004]

if you used octane boost, look at your plugs now. That crap will coat your plugs with some orange coating. Just use chevron 91

[@wambam3564]

I noticed you didnt mention a tb gasket when reinstalling?

[@erickc5914]

Hey Chris, I’m finally getting the chance to do this, is it a must to remove the TB to clean it? Is removing the intake to it and cleaning it on car a sufficient cleaning??

[@mycorvettelife]

I would remove it. You don’t want any debris going into the intake manifold.

[@memfisser69]

I cleaned and polished the throttle body a few months ago and now Im getting a “replace mass air flow sensor”

[@sspp3065]

what year is your vette you have some differences i see like 2 braided fuel lines going to the fuel rails

[@mycorvettelife]

1998

[@roybishop6110]

Great video.Put a catch can on there you'll never have to do it again.

[@maxmccoy9744]

Hi Chris I have a c6 (2006) it has 10 mm battery bolt buy it is a top post I thank all side post are 8 mm.(hi all first time comment)

[@mycorvettelife]

That may be right. Thanks!

[@randy2.0kitt]

I feel like wire brush was not good on the inside...

[@mycorvettelife]

Seems to be doing just fine.

[@dankaitschuck4440]

I have an 05 and I am having a starting problem. When cold it starts right up but after it has run even a little and sets for a time and I try to restart it the engine turns over but will not start for 3 to 4 seconds. I have tested the fuel pressure and that is not the issue (you can smell the fuel during that 3 to 4 seconds). It was suggested it could be the camshaft position sensor so I replaced it with a GM one and no difference. Wondering if the throttle body could be stuck and not opening right as the engine starts cranking? This is a very consistent problem of late and any suggestions as to what could be the cause of this problem is appreciated.

[@mycorvettelife]

Sounds like spark to me. Have your checked your plugs?

[@dankaitschuck4440]

@@mycorvettelife Yes I have checked the plugs and all look great. I even put new spark plug wires in the car. I had a timing light on it for a while and would watch it as the car was turning over. I did notice at one of those times that the light was weak but once the car starts there is no problems. It runs strong, good execration and 25 MPG on the road.

[@164hozey]

Can a throttle body go bad? I have codes p1220 and p1221 so I’m assuming it’s just the throttle position sensor but someone told me I should replace the whole throttle body

[@mycorvettelife]

An electronic throttle body, like anything electronic, can go bad. Luckily these TBs are cheap.

[@164hozey]

My Corvette Life could you link me to a replacement? Because I tried searching for one online and it’s around 500, that’s not cheap lol

[@jeffgardner7265]

Is there a throttle body gasket to clean off and replace?

[@mycorvettelife]

The gasket is reusable and stays in the intake manifold.

[@khaledkhan6900]

Hello any clue how much does it cost to reprogram throttle body once changed ?

[@mycorvettelife]

Never heard of reprogramming a TB. You mean a tune? Cost depends of the tuner. $500-800 range.

[@tripppetry7886]

Is this similar to a 2006 GTO? Can’t find a video for it

[@mycorvettelife]

Yes

[@Theclassiccarnut]

If a car could talk. Your Vette would be thanking you for buying it. Especially how the last owner kept it.

[@mycorvettelife]

I second that. That video Chris posted of what the engine bay looked like made me cringe.

What does the bypass coolant line do?

GM designed it so the coolant goes through the throttle body. It's not necessary unless you are driving your Corvette is freezing conditions.

Could have removed the throttle blade for cleaning. EGR hose could have been simply capped or plugged. Throttle body looked amazing.

Yes in the intake manifold. It is reusable.
