This channel will be dedicated to rebuilding all aspects of a 1984 C4 Cross Fire Injection Corvette, but most of the information seen here other than engine management is similar to most C4 Corvettes that were made between 1984 to 1996.
May looks like a dumb question. The hole in the hood, when it is closed, does not match the holes you are opening. Why the people opens a big hole as it is matching the one in the hood if they don’t match? I just did it on mine as you said but I have another idea I will post later
It does not look like mine on the later cars it has more than 1 wire but it should be right around the oil filter area. Here is a picture of what yours look like. Thanks for watching! www.zip-corvette.com/90-96-oil-temperature-sender.html?gad_source=1&gclid=CjwKCAjw5Ky1BhAgEiwA5jGujkOo0qb4Z4O-Zg259zBLyQn182rrePOE7byF2WLl7NNjqqqlV9YkkRoCn10QAvD_BwE
I owned an ‘84 ‘Vette in college. I took that half flow crossram off that engine and installed a ‘77 L82 aluminum Q jet intake with an 800 cfm Q jet. It’s amazing how much more power that engine made after that.
Ya, the intake manifold is very restrictive. I was told the intake passages were so small because they were trying to get a lag/dead spot out of the rpm range by increasing the air speed into the cylinders. Thanks for watching!
Great videos! I will have to suggest getting a microphone to help with the audio on your intro. I’m having a no crank no start with my 1986 C4. Seems to be a common problem?
@@micahcastillo9113 Yes I did. I spent a half of a day checking and ohming out the wiring from the ECM to all the different component's. Turned out to be multiple problems with the throttle body's they were put together wrong so it had low fuel pressure. One of the new injectors worked but I don't think it was the correct application for that car causing half the engine to lean out and finally after getting it to run on all 8 cylinders the idle was high it took 6 IAC valves before getting 2 that would work and let it properly idle under 1500RPM. Thanks for watching!
Thanks Mike! Unfortunately yes, it will take more time and a little more trial and error without the tool, But at least it came still be done fairly easily.
nice video, i couldn't find the special screwdriver, so i set it by taking the top off, i found turning the pressure screw backwards to what i expected
I've looked for that tool as well as the IAC block off tools and cant find either. I guess they stopped making them several years ago. Thanks for watching!
Is there a solution for upgrading/updating the refrigerant? Cant buy R-12 anymore... Buy a new AC compressor that will retro fit or is there something else?
Yes, You can update the system to R134a you need a kit to retrofit the R12 valves to R134a valves which cost very little. I would also change the accumulator at the same time. R12 uses Mineral oil and R134 uses PAG oil when you change everything over add Ester oil with UV and it will mix with the Mineral oil left in the system and the R134. You cant put PAG and Mineral oil in the same system those don't play well together and you don't want to use anymore Mineral oil with the R134a. Also vacuum out the system real good to get the moisture out before you charge it this also helps suck in the Ester oil before you add R134 or you can add the oil to the inlet side (closest to the evaporator) of the new accumulator VERY IMPORTANT DO NOT PUT THE OIL IN THE OUTLET SIDE (going back to the compressor) AS IT WILL SLUG THE COMPRESSOR AND RUIN IT! I hope this helps!
I’m needing some help with my 4+3. I replaced the clutch and I’m about to put the transmission back in but I can’t figure out where that line that connects to the tear top transmission near the output shaft connects near the engine?
Sorry bad video I'm trying. Put one bushing in the control arm, Then send the shaft through the control arm side without a bushing the shaft must go in big washer side first install the big washer after you have sent it through the control arm. Now slide the small washer onto the shaft and install the bushing then add the sleeve and tighten the nuts add locktite. Thanks for watching! It was one of the first videos I shot some of my later stuff is better.
Knock on wood I haven't had to do this yet - amazingly still originals without issues - really the only parts that haven't been rebuilt/replaced (damn I hope I didn't just jinx myself)! These really aren't any more complicated than a carberator, but they have their own mystique which I think keeps people from getting in and rebuilding them correctly. At least you can still get the kits as many other pieces parts are not unattainium (i.e. EGR solenoid). I'll keep this bookmarked as it's obviously not if but when I'll be repeating this process. Thanks for taking the time to do the video.
Ya, they really aren't bad at all. Thanks for watching! Hopefully you have subscribed because I have 3 more coming out in the next couple seeks on how to finish the process. Reply
In the Lariat all the windows are auto up and auto down. Front and rear windows. I have a 2023 Lariat AWD 2.0l in Alto Blue, blackout package and 4k tow package. I like it a lot.
Thanks for the video. Can you do a video walking through the high pressure and low pressure switches etc? I have a 1984 and I'm trying to troubleshoot the AC. Your other vids where great and helped me while I was replacing my head gasket and putting things all back together. Thank you!
Thank you! I will try to put a video together for you in the next month, I'm working on a couple other things right now but I will definitely do it for you. Thanks for watching my channel!

My 85 Z51 that I bought almost new had the bronze tint top that was gorgeous. Until it was stolen. Replacement was pricey even in 87! I miss that in my later life crisis 84. It has the standard roof. Maybe someday.
Ya, depending on what color car you have some look better with the Bronze and some look better with the Blue tint and of course I think they all look good with the color match fiberglass top. That sucks having it stolen! Thanks for watching!
My OD works most of the time but sometimes it gets finicky and likes to disengage with even a modest pedal pressure. I’m wonder if replacing the (probably) original switches would help.
I think it might, it worked on mine. depending on what year you have it could have several switches and the First gear switch i the one most likely to go bad do to the amount of times it goes in and out of first. I think that's why they eventually eliminated the first gear switch. Thanks for watching
I used Dupli-color engine enamel with ceramic in CAST COAT IRON - DE1651 I hope this helps I thought it was a good match. Thanks for watching my videos.
Love the series. The process reminds me of matching the Strombergs on my TR6. My other toys include a 66 GTO TriPower and an 84 Vette. I suppose I have a thing for complicated intake systems!

WOW, You sure do like the complicated things🤣. Thanks for watching, I glad you enjoy them. Some are defiantly better then others fortunately I'm a better mechanic then a film maker. 🤣Thanks for the comment!
Thanks for watching! I'm afraid I have too much money in mine though. What are you going to do 🤣 I enjoyed putting it back together. I hope you will like and subscribe I have over 50 how to videos some are better than others , but it would be great if they were helpful to people out there.
I appreciate all of your videos for your 84 corvette. I just recently purchased a 1984 with the Doug Nash 4+3 transmission 3 weeks ago. It’s in great condition considering its age and only has 70,500 miles! I watch and use your videos for tutorial in conjunction with the FSM. Your video’s give me confidence to tackle the jobs I’m currently working on! Thanks so much!
WOW, @84c4corvetteguy5 GREATWORK. I have owned my silver 84 vet 3+4 trans in 1984 still own it with 37K original miles always garaged.' How can I speak with you?
Interesting... just starting on my D44 tonight, the stubs have little cups that shield/protect the seals and the batwing bolts are a 15mm head instead of 13mm. I bought a gasket to use for the housing/batwing union, what's your take on gasket vs straight sealant? I also noticed it looks like you went with the SuperPro bushings... do you like 'em? I got a full set to do my '85, doing the rears while the diff is out/apart.
Ya Some came with the cups and some did not. 1984 was the only year that a stick car came with a D36, 85 they switched to the D44 if you had a stick shift car. Mine did not have a gasket just sealer and most of the Dana's I have serviced did not have a gasket from the factory of course these were mostly Dodge trucks. Love the Super Pro bushings, I bought the entire kit myself there are several videos that I made on them Hopefully it can help. Thanks for watching! Reply
Thank you buddy, I'm glad you enjoyed it. C and S Corvettes in Fla. has a kit they put together for the C4's I think they are the importer. That is where I got mine.
Sorry, but I'm a Mechanic not a film maker if you watch it to the end I show the back side of the alternator and all the bolts as well as gave a explanation. but I thought it might help some people as it was a series of videos going all the way down to the head gaskets.
The ThermAC sensor is designed to maintain 100°F to prevent carb/throttle plate icing. The wet intake like a CFI needs that warm air for fuel vaporisation and the injector pulsewidth is calibrated for 100° air. I'm an ancient MoPar tech and there was a way to tweak our version of the ThermAC sensor to make sure we got the needed sir temp. I'm unsure if there is a way to tweek the GM sensor. The Tuned-Port depends on the coolant flowing thru the lower part of the throttle body for the throttle plate icing issue. TPI owners in cool/cold climates can get into icing issues if they do the coolant bypass for that extra 1-2hp.
Absolutely right, these were only used on carburetors and throttle body's with a wet intake systems Once they changed over to dry intake systems with throttle body's they started running coolant through the throttle body's to prevent icing. Thanks for watching!
No your wiring harness wont match up to the combo sensor. Could you do it, I guess so but you would have to change the connectors on your factory harness, considering all three sensors are still available I would replace what came out of your car. Thanks for watching!
Passenger rear head/coolant fan = Advance auto - Carquest ACA1267, Drivers front head/Temp. gage = A/C Delco 88865046, Intake manifold/ECM = NTK304036, I hope this helps. Thanks for watching!
@@user-jh2ki4tz5s Here is a link, Did you put in NGK instead of NTK? but the part # looks good. You will also need to change the connector on a 84 because they no longer make the two wire umbrella sensor for the ECM. www.corvettecentral.com/search?CurrentSearchCategoryId=&q=coolant+temp+sensor&Years=1984
I was going to rebuild mine but when I took it apart I found that the front bearing surface had a serrated edge and it was glued into the housing. I tried to find a bearing with a serrated edge but couldn't find one anywhere. When I called the rebuilder he laughed and confirmed that the bearing was indeed glued and serrated so I just sent it out to have him rebuild it. He said I can't believe you got it apart without cracking the front housing. Thanks for watching!
That's awesome yours still works. I had No warning at all, Came to a stop sign and the car stalled went to restart it and it seemed like a dead battery. The battery was old so I just went to the store and got another one only to find out now it started but the belt was smoking bad. Thanks for watching!
