The movie has been re���ed for a long time. The show takes place. Follow on 23rd week on Allッ看! So pretty much very simple engine. The ride from the 350 small block, they took the small block Chevy, cut cylinders 1 and 6 off, slapped the block together and boom, that's how the 4.3 was born. Now this is a throttle body injected 4.3, this is the HAL35 RPO code 4.3 which is the 200 horsepower rated 1 and 260 pound feet of torque or foot pounds I should say. Now some things that I've come to really hate about this engine are things like this. I had a little around here, so then a little research and over time if you ever come across that GM line, apparently a lot of Chevy's get it. With this case it's not the alternator. Which is our if you ever have the engine running you can take a screwdriver and if you stick it right here on this bracket where the thread from the bearing goes into and you listen and if you can hear the whining or air then you know it's the idol or pulley. Another thing is this bypass hose here, this one, it'll dry and crack and then a lot of time little clog and like right here it's got a kink, I need to fix that. I just did a timing chain, water pump and time and cover. Now with that stuff it was very simple, you pull the front, you pull the time and cover off which was stupid because 97 and up they took the steel time and cover off and then they threw a composite one on there which you had to replace upon removal, corn and GM. There were several TSP's for this engine because of people coming into the dealership and complaining that the engine is lacking power. Now that I believe was caused by this at a distributor issue, I believe that's what it was. Now another thing that is commonly known to go wrong on these is if you have throttle body injected from the years 98 to 04 you probably end up running it back in leak from this little O-ring that's underneath this bonnet. If you take the wing nut off of here and you pop this up underneath here or inside of the bonnet, if you take it off and you look inside there's an O-ring a lot of times on the heat cycles depending on where you live and how hot the engine is running, the O-ring will actually shrink and it'll crack and you can end up running it back in leak from here. Now another thing was the distributor. A lot of times if you go to replace this distributor, these ones, the originals, the cap was very, very sensitive to moisture. A lot of times it would go bad just because of some spray from rain. You catch, hit the back of the firewall and will run down. Inside there, water gets inside the cap and it fries it out. You go to replace this distributor, you put it in and if you bend the shim or you do anything to mess up the shim that holds it, it'll throw the P1345 code which is pretty much crankshaft, camshaft, correlation, fault meaning hey, the distributor is moving around and it's detecting it which is throwing that trouble code. P449, the trouble code. Pretty much means hey on this engine you've got to replace the EVApsilon 9. That's just the easiest way to get rid of it. You can get that cylinder on for less than 20 bucks depending where you go. AC Delco definitely is the recommended replacement brand for these. Now when you replace it, it may throw 446 which accordingly across multiple forums and through several service manuals. P446, take a new gas cap and put it on. It's the old one. Apparently with the S10 series pickups, the gas cap goes bad. Now the next thing, which is this is a plus here, is the ignition coil. Ignition coil, there's only one so you don't have to worry about it like the 530, you've got eight of them, time that by 40 bucks or so, especially if you're going to form it with the MSD. You get MSD or XL in this brand, AutoZone in advance, they do carry this exact style and they do have MSD and XL. The reactors were trash when they first came out because if you had the multi-port fuel injection which is what this one is, I believe the central port fuel injection as well. The injectors that GM put in here, they were garbage. A lot of times they would break, they'd crack and boom, that's a gas everywhere. Or you have something to simple, it's getting bad gas, clogs an injector, boom GM said nope. We designed it to where you have to replace it so that's more money in our pocket. So there you have it. You can get the Tamer X injectors, personally I wouldn't recommend it just because if I'm going to do anything that's very vital to the engine and it's you know, drivability. I definitely would go OEM, PC Delco you can pick it up for like 240 bucks or so but that's the updated injector system which is, you know, because these are spider injections. The poppits that go into each of the intake, the intake on the manifold, they're removable. So if one gets clogged you can take it off and place it with another. Now another thing was on here the thermostat. Thermostat's a round top of the engine, it's very simple to remove and replace if you ran into a problem. Intake manifold, you can swap manifold, you can even get brands like Holley, Jax, or light fans like stuff. So yeah, that's pretty much all there is to these 4.3's here. Now the, come down to the time and cover here, down in the time and cover which sits behind the water pump, you replace it. Just be careful to when you set it back in because the all-pan gasket, half moon that goes right under the crank, there's a little lip like I was saying before there's a little lip that sits on the time and cover. When you go to put the time and cover in, that gasket can sometimes get pushed in and throw the gasket off. And then when you drive, especially if you're going downhill, oil starts spewing all over the front of the block. The easiest way to do that is on each side of the all-pan there's three bolts. I believe they're 13 millimeter bolts. You just unbolt those first three accordingly and you can move the pan down a little bit, slide the time and cover on and bolt the pan right back up. You know, intakes with these, cool things were, if you had the Vortec one, they made special Vortec intakes with these 4.3 engines. Hatters, yeah, you can get headers. They have JBA headers, they got long tube headers for this engine they got. It was pretty much if you go back to looking at the 4.3 history, there was the 4.3 which was turbo in the GMC cyclone and the GMC typhoon. So yeah, you can definitely run headers. That's a pretty unique feature about these. You know, common things that are known to go bad, AC compressor, alt-nader, right on top of the engine. You don't have to open the hood and dig way down, it's at the engine and you're like, hey, where the heck's the alt-nader? So that was a unique feature with this. They still use this engine to this day. It's not manufactured by GM anymore, they discontinued it as of 2014. It's actually manufactured with a different displacement rating and it is a marine application. Built by Merck Cruiser, they pretty much bought their boom cranksiner rights to this engine and did a little tweaking with it, increased the displacement 4.5 and now you've got a lot of boat motors. So yeah, that's pretty much it. That's all I can say. I've driven this engine for about 10,000 miles now, it just picked this truck up a little while ago. It's a 2002 S10-ZR2 with the wide stands. And hey, this engine is, you know, maintenance-wise, been a paint. I've had to change everything on it. You know, if trucks had 14 owners, so you can't get a little sense of just pure abuse on this engine. Now these engines are known to go three or four hundred thousand. If you really take care of them, keep up on the wheelchanges and all that fancy jazz, you know, like they say, if you take care of the engine, it'll take care of you. That's certainly true with these. But yeah, I think that's pretty much everything with these. If you guys have any comments and questions, please leave them in the description or not in the description in the comments section below. Try to keep the comments section clean. And so that's educational for everybody. And with that being said, I hope you guys enjoyed. Thanks for watching. And subscribe for more content. We have some more videos trying to get back into up regular uploads. And I'll be going over a lot more stuff with the 4.3 and some real technical stuff with just the S10 as series pickups.
