#245 of 2018 Some information that may be useful...

Janel: I have a 2000 S10 with the 4.3 engine that I've had since new. I recommend you go to about 1,000 miles and change the oil. This gets any small metal pieces left in during manufacturing or that wore off during break in out of the engine. Check the drain plug tip when you change it--there is a magnet mounted on the tip, and if there are any metal filings, they will stick to the drain plug. Then, go to 5K-6K miles and switch from regular oil to synthetic. This will keep the inside of the engine like new for at least 175K-200K miles. While the synthetic is more expensive, you can extend the oil changes out to what some call a 5/10 cycle. What that means is that after changing over to synthetic, go to 5K miles, change the filter and top off the oil. Then go another 5K to a total of 10K miles, and change both the oil and the filter.
Joemilan: As far as the timing chain goes, if you do what I recommended to janel and go to synthetic oil, you will probably never have a problem with the chain. If it does break, it shouldn't cause any problems. The 4.3 engine is basically a 350 cubic inch V-8 with two cylinders chopped off. That engine is one of the best and longest lasting engines GM has ever made. It has plenty of clearance in the cylinders for the valves to clear the tops of the pistons if the chain does snap.
jjstokes0430: Check the owner's manual and then check the transmission to see what kind of fluid is in it. I've heard stories of the manual calling for ATF fluid in a manual (yes, many manuals now have ATF in them) while the factory may have put 10W30 oil in the tranny. If your manual calls for 10W30 oil, try changing it to a 20W50 synthetic oil. If that doesn't help, you may want to try another dealer or a tranny shop for another opinion. If you work on your own truck, you may want to put the truck on a lift, start it and then look at the linkage. You may have a loose or rattling piece of the clutch linkage or a cable rubbing against the floorboard, causing the noise. I haven't heard too many problems about the 5-speed trannys lately, but they did have trouble with them several years ago. At one time, the tranny was made by Suzuki for Chevrolet, and it wasn't holding up well. I know of one guy that had so much trouble with it while it was under warranty, that he was able to force Chevy to buy back the truck.
Good luck to all!
#246 of 2018 '94 S-10 Wiper Problem - Reprise
Sep 01, 2002 (9:28 am)
I haven't looked here in a long time but I did note that somebody was looking for my earlier post on wiper control circuit board problems with the '94 S-10.
What I found was that the solder-joints on connector pins on the board were "cold" (dull color on surface of solder and cracks around pins you can see with magnifying glass). This causes the wiper motor to operate intermittntly - sometimes appears to be heat related (worse when warm under the hood), you might also be able to get the wiper to run sometimes by wiggling harness close to the motor...
You can remove the control board from the motor assembly without removing motor (removing the motor is a real pain and the motor is not the problem!). Get a small soldering iron and re-heat the solder around connector pins by touching each pin connection on back of board with a drop of fresh solder. This fixed my wipers - no problems now going-on 3 years! (You can buy new Circuit Board from GM - I think it is $40. The solder repair costs about 5-cents!)

Thanks for your advice on the break in - I wondered what I should do when. And, I've never had a timing chain incident with the other Chevy's I drove to around 200K. I religiously had the oil changed But aren't the timing chains plastic now?
I guess it couldn't hurt to change the trans fluid earlier - when do they start throwing off bits of metal?
And your comments on the 4.3 6cyl were good to hear. I was scrambling to find one of the last before they come out with their new 6cyl., which I bet has an alum. head.
Someone talked about a problem with a seat not locking - had that same problem on an Astrovan - passenger seat. Never found a solution - but didn't look too hard , so it's not a new problem - it was an 86.
And someone was working on a blower fan. Replaced one on the Astrovan and turned out to be a switch under the control on the dash. Easy to replace and took back the new blower fan.
Before that, junk would fall into it and it'd squeal and hang up as someone had just cut the screen to get to the windshield wiper motor. Fixed the screen and no more problems.
I had the Hayne's manual on the van, so I could read it and decide if I could do it or before I'd take it in and know that the mechanic was really going through the trouble he said. But, for the engine codes, I found them in a book at the library and zeroxed those pages. Wow - that opened up a whole new world.
Thanks again, Joe
#248 of 2018 manual trans fluid on 97 s10 2.2L
Sep 12, 2002 (5:33 am)
I want to change the manual trans fluid on my 97 s10 xcab 2.2L. My user's manual recommends "GM part 12377916 or equivalent", but the dealer wants $11.00/qt for this crap (need 3 qts.). Any alternatives?
#249 of 2018 janel84: glad to be of help.....
Sep 12, 2002 (9:50 am)
As for the timing chain question, years ago (late 50's into the early 80's) GM used lots of timing chain sets that consisted of steel gears coated in a nylon plastic material. Most timing chain failures were not the chain breaking; they were caused by that plastic material shattering and letting the chain slip. I'm told that all GM engines using timing chains (belts are another issue) are using all-steel chain and gear sets. That means that with good maintenance, the chains are good for 150K and as much as 200K.
cajun: If you manual doesn't tell you what that fluid is, go to a good independent shop or parts store and have them check to see what your transmission calls for. The fluid the dealer wants $11 per quart for sounds like a synthetic ATF. If you can't get a straight answer, go to some Internet sites that sell GM parts and order the fluid. Try www.gmpartsdirect.com or do a search for GM dealers on the web using Yahoo or Google. Even if you have to pay $11/quart, just remember that $33 is small change compared to a new tranny.
#250 of 2018 2.2 vs. 4.3 engine
Sep 14, 2002 (1:05 pm)
I am shopping for another S-10 used. My last had a 2.8 engine V-6 - EXTREMELY reliable. Almost 200,000 with NO engine repairs. That's no longer available. I'm having a hard time finding a 4.3; almost all seem to have the 2.2 4 cyl. Any experiences with these engines? I have heard the 2.2 is underpowered. Is it durable?
#251 of 2018 Seat back shakes when empty
Sep 15, 2002 (7:22 am)
Just got a 2002 s10 Crew Cab. The passenger seatback exhibits a side to side shake when empty even at low speeds. Is this normal or could it be a defect?
Sep 16, 2002 (5:03 am)
I have a 5spd x-cab with the 2.2L. It's a dog, but on the plus side I average 24 city/29 hwy. It's decent enough if you're just tooling around town. Only problem at 44K miles is a currently leaking valve cover (seems to be common on this engine). Don't even think about getting the 2.2 with an auto trans.
#253 of 2018 Go with the 4.3!
Sep 17, 2002 (6:27 am)
If you are buying it to be a truck (hauling or towing) the the 2.2 shouldn't even be considered. GM puts the 2.2 in that truck for basically four reasons. One, it helps raise their CAFE, Corporate Average Fuel Economy, which is closely monitored by the EPA bureaucrats. Two, it helps it compete with the four-banger Ranger and Japanese trucks, often advertised as price leaders to get you into the dealership, where they will try to sell you a V-6 or V-8 truck. Three, they sell alot of them to rental car companies and fleets that only use the trucks for light delivery. If you own and operate 500 trucks, a difference in 3-4 MPG makes a huge dent in your budget. Fourth, if the Chevy Cavalier and other lines that use the 2.2 engine are not selling well, GM can easily modify their production line to make the 2.2 engine in a truck configuration (different oil pan and other minor modifications)
I have the 4.3 in my 2000 S-10 extended cab. Reliable, quiet, never stalls, quits, runs hot or idles rough. It tows and hauls well. It easily breaks the tires loose if I want to, and always 'runs with the big dogs.'
Based upon comments from owners with the 4.3 engine in the "Older S-10" discussion, this engine easily lasts well over 150K. I'm tired of car payments, so when mine is paid off, I hope to break 300K on synthetic oil before I have to buy another one.
#254 of 2018 Automatic Transmision Upshift Clunk
Sep 30, 2002 (5:24 pm)
I have a 2002 Ext Cab 4wd S10 with 9000 miles on it. There is a noticeable clunk when the transmission upshifts from 2nd to 3rd, especially when accelerating slowly. I have checked all the posts on this board and haven't seen any mention of this. There is a TSB out on this, number 01-07-30-042, but being a consumer I can't find the details for it. Does anyone know anything about this problem? Thanks!
