My radiator fluid has turned into sludge. I think it is because one weak day when the guys at Jiffy Lube said you are low and asked to top it off I said sure... I think that was a big mistake. Anyways, I think they added the regular blue coolant to my orange dexcool. And although the engine is working fine, underneath the radiator cap there lurks a bunch of lovely sludgy muddy looking stuff. I originally was thinking of going to the dealer and having them flush and replace it. Although, I've been looking around on the internet and reading horror stories about Dexcool. Can you switch back to the classic blue green antifreeze after Dexcool if the system is flushed thoroughly? Or should I just stick with the dexcool? |

Replying to: tjdude (Sep 05, 2005 3:34 pm) TPM could be TPS, which is throttle position sensor. I had mine replaced 2 weeks ago because at a stop, when trying to throttle up, it would lurch and studder like it was out of gas, when I shut down the motor and started it again, it would run fine, I have seen alot of simular problems on the site, and this is a common problem for the 2.2L. so try replacing the sensor, they run about $45 atleast, mine did. good luck, hopes this helps T

| I have a 94 v6 122,000 miles automatic, the problem is the truck runs great except it can't seem to shift easily into second gear, the truck drags and there's a loud almost roaring sound as the truck fights against itself to gain speed, however, once the tac hits 3.5 then it quickly shifts into second. All other gears are operating fine. The oil change done just two weeks ago is now dirty, the new sparks are filthy. I just had the fuel injectors cleaned. My truck won't start unless my foot lightly touches the gas pedal...which I never had to do previously. The local technicians can't find the source of the problem. | |
Any hints/tips on replacing the alternator on a 2001 S-10 2.2L 4cyl? It looks pretty hard to get access to - not on the top of the engine like most. Some parts will have to be removed to gain access, but I'm not sure which ones are best. Have replaced alternators before, but I'm pretty much of a mechanic wannabe...
