I don't know if this will help, but I just did some radiator work on my '01 S-10 with a 4.3. You might have a cracked tank inside the radiator.

hey you could have problems with your choke i would check that and it could also be your fuel to gas ratio got thrown off somehow...i would bet on the choke tho thats what it sounds like.. gl to you

I have a 1996 4.3 with a cooling problem. It seems that no coolant is running through the engine and the heater core. I just replaced the pump and the thermostat and filled it with the correct ammount of orange anti-freeze. what could the problem be?
[email protected]
first off do not use the orange anti freeze how do u sleep at night knowing its eating away at your engine take that crap out and replace it with the green.. make sure your radiator pipes dont have any kinks in them so that it would block the coolant

My 2001 S-10's fuel gage is as temperamental, as I'm quite sure yours are. But lately it has been going to "empty" while sitting at the stoplight. Anybody else had this happen, any suggestions?
yes my sonomas fuel guage is quite tempermental also any slight slopes change fuel level dramatically thinking i have more gas than i really do then i get pissed off..if i put my car into neutral my guage will go down to empty and stay there for a while witch also sucks but reading all these other peoples problems LOL it could be a hell of a lot worse

Hi, I have a 97 V6 Chev S-10 and it has been idling rough. It vibrates even more once put in drive at a stop. It starts wierd sometimes too. It seems like it 'chokes' when trying to start. I've replaced the fuel filter, distributor cap and rotor, spark plugs and wires as well. Any ideas?

In addition to a rough idle and wierd starting my 1997 S10 'diesels' when I turn it off. It makes funny sounds right after I turn the truck off and goes away in a second or two....could this be my catalytic converter?

I used to think Chevy was the truck to buy, In fact we did, had fords also, but after this 2500 Duramax Diesel, we have currently replaced the injectors three times and we are only at 87,000 miles. The last set only lasted 5600 miles! So that is four sets of injectors since the truck was manufactured, each at a cost of $4-6000 (covered under extended warranty now, but that all ends at 100,000 miles!) The truck has been extremely well cared for, bought it brand new for the longevity diesels are well known for, and now, I am afraid to take it to the end of the block and all GM can say is "we will give you $3000.00 off the purchase price of a new one! Not a problem we are only $36,000.00 into this vehicle, and I cannot even get a trade in amount enough to pay off the current loan, so who would you say, Ford or Chevy?????

Best bet would be synthetic. Your motor is well broken in so synthetic would be ideal. It gets the heat to your motor faster therefore better for cold starts. Not sure what grade you need...I know my V6 is 5W-30

I have a 2003 chevy s-10. The problem I am having is this: driving at constant freeway speed; going down a grade; fan comes on and engine RPM drop to <900. No problems with performance, can stops after 10-30 seconds and rpm go back to normal. Mechanic can't find any problem.

I have a 1994 s10 with the 2.2 and 5 speed. The enging is on borrowed time. Question, does the replacement engine need to be from a vehicle with a manual trans? Can I use a newer 2.2, like a 2000 or 2001? Are cavalier engines the same? If so what year cavaliers were they in??? Thanks so much

My ABS light came on, my brake light came on, lost my speedometer and it woulndn't shift out to third gear. This is on a gmc sonoma 2001 year model any ideas?
Yes, had that one on my 2000 S15, theres a (i think it's called) a speed control module in the transmission. It's a quick inexpensive repair Less than $100.00
