Time to change your wheel hubs.

In that video, there seems to be more space behind the rad than a Trailblazer. But I have had the waterpump off, so I know how to get the fan clutch out. (I use a short length of chain and a longer bolt to stop it from spinning, and a spud wrench with pipe length for leverage to loosen the nut.)...

You make some good points. Information wise, there was zero misfire history until it very suddenly died at idle, and cleared itself for a few minutes and died again, this time for good. Thankfully, I only had a few miles to go but the Check Engine light started flashing the last mile. History...

On steeper upgrades, don't be afraid to drop to 2nd if that is what it takes to keep the RPMs above 3000. The secret of towing is to keep the RPMs up and just live with the gas mileage you are getting. You can also find the sweet spot of RPMs by the position of the gas pedal; if you can't decide...

Yes, I was overthinking it. I put on a low-power battery impact and after a couple of hits, it popped right out. It took longer to remove the wiring clip with cold fingers than it did to replace the coil pack. Based on everyone's advice, I was very careful tightening the bolt. I use a 1/4-inch...

Trust me, it's Winnipeg. Anything I would spray to cool it down would just be warmer than the ambient air anyway. So far my thoughts are to do it when cold (brrr) but I am speculating that a 1/4" impact might just suddenly 'break free' any corrosion on the threads, whereas the ratchet might...

Sudden misfires and a flashing check engine light made me break out the Tech 2 and confirm cylinder #3 was constantly misfiring when warm. Thankfully I have a new Delphi coil pack in a box and will pull it out tomorrow. I am just worried about breaking off the bolt in the block while removing...

I was looking for a bit more forward rake, and I am big on handling. (I have had my Trailblazer on the road race track a few times just for fun.) Here are some guidelines from an old time road racer. To help reduce the built-in understeer, one stiffens the rear. To reduce built-in oversteer, one...

While we are on the topic, can anyone post the Tech 2 screen where one can command cam angle. Some people have reported that 'exercising' the solenoid can sometimes help correct a brief and momentary slow operation when cold, that sets a troublesome code. I have shortened oil life changes, which...

In addition to the above advice, find a gravel road and brake hard until ABS kicks in. Try this a few times and it may work to stiffen the pedal.

Trust your oil life monitor, but I would also change it once a year even with low mileage usage. Personally, I never change oil without a filter, but with your low mileage, the volume of oil the I6 uses and the quality of your filter, it is not really "dumping dirty oil back into the engine."...

Have you replaced the water pump before? Not an easy job, but with the help of this forum, I found ways to make it easier. I didn't remove the shroud and I used a short length of chain and a longer water pump bolt to hold it in place while I broke the nut loose. I ended up trying different tools...

Wow. I had to take a look at Rock Auto to confirm. I seriously cannot believe they even list 160 and 180 degree thermostats for our platforms! Good Lord, they do. Listen to the advice above. ONLY get a 192-degree thermostat. A 160 or 180 degree thermostat may seriously shorten the life of...

I see. You are in the Trailblazer/Envoy forums. The best thing is to start a thread specific to your case in the H2 forum. While both have GM software, the TCCM is completely different. On the 2002 Trailblazer/Envoy, lights coming on for test phase and then all going out indicate a defective TCCM.

What vehicle? If this is a 2002, skip the whole thread and look for a TCCM off a newer vehicle. High failure rate for 2002s, and those are exactly the symptoms of a bad TCCM.
