I by chance had an oil change and went to synthetic oil. The minor tick noise went away. I did notice a slight bit more power.

I noticed my ticking noise when leaving school one day. It was a small tick tick tick tick noise, kind-of like a metronome sound, but here recently it's gotten louder. Sometimes it'll skip a tick or two and keep ticking. Sometimes I can revv my motor a bit and it'll turn off, but when I let off the gas, it'll start right back up. I haven't had my problem fixed yet, don't have the money to, really, but it's very annoying when you're outside the car. I can't believe I've found this site with so many others with the same damn problem.

I started noticing the problem approx 1 month after my wife and I took it home. As with everyone else it was more annoying and embarrassing than anything. After researching on this web site, there was no denying that it was the fan clutch. Found a new fan clutch at part source for $289 and $130 labour at a small out of the way GM dealership and she's running quiet!!

I've been hearing a slight ticking noise in my trailblazer for the past few weeks. Suddenly it started sounding much louder (almost like sticking something in the spoke of a bicycle) so I decided to take it in to have it looked at. The car's driving fine but knowing my luck (I only have two payments left to have the entire car paid off) I figured I better do whatever I can maintenance wise to make sure it runs for a while. I took the car to Firestone and explained the problem as a loud ticking or vibration which sounds like it might be coming from the engine. They called me back not twenty minutes later and tod me they think I might have a rod knocking and suggested having my engine replaced/overhauled/rebuilt. They told me they don't normally handle such a large problem and when I asked them if they could recommend me someone they said they'd call around and would get back to me. They then called back and said it would cost $4325 for the engine assembly, $1400 in labor to remove and replace the longblock and $344 for a PS527 install kit. The total with tax was going to be $6647. Being a girl and having no way to know if they're screwing me...I called an engine repair shop out of the phone book who told me they could replace the engine for $2300 dollars. I'm slightly confused about the significant price difference and now after reading everyone's comments on the ticking sound coming from their fan clutch I'm wondering if I even really need a new engine :( Grrrr...

I have had my Trailblazer since it was new and have had almost zero problems with it. The only things have been little annoyances. This ticking noise began a few months ago and I have not been able to figure out exactly where it is coming from. It echoes too much under the hood to pinpoint it. I suppose the most common diagnosis has been the fan clutch. I am trying to wait it out and find out if there is another answer since replacing that hasn't worked for some people. I am disappointed that Chevrolet has not stepped up to the plate with a solution. This ticking noise drives me and my wife crazy and everybody asks us about it.

Those of you with the ticking sound faced with a $750 repair can save a wad of cash. Rockauto.com has the clutch for $141, and 2 other more expensive models. Others on the web likely have pricing better than the dealer. It's easy to replace, a few bolts and an electrical plug. Unhook your negative battery cable first.

I just recently bought a 2003 Trailblazer LT. It had 61,000 miles on it when I drove it off the lot! It now has only 72,000 miles and as of October 12th, it started making the (TICKING) noise! IT is that clutch fan and it does cost about $750.00 to replace! That is more than the taxes I payed on it!!!! If I had known this was a common problem with Trailblazers after 60,000 miles I probably would have just settled for a Ford, or worse, a Dodge!!! Chevrolet, I have become real disappointed in you! What an embarrassment!!!

I first noticed "MY" ticking noise just after my warranty expired. I brought this to the attention of the dealer at the time but was told that it's just "normal" for the cooling system and engine to "tick" like that. B. S. That's a line of crap if I've ever heard. Every trailblazer that I come across does the same thing. Is this what we get for our hard earned money? If you know what it might be please let me know. My trailblazer now sits with 51K miles on it and it's still ticking away!

When you start the car or sitting idled you can hear a ticking noise. The car dealership told me it was the clutch fan that was causing the ticking noise and that it would cost me $700 to fix. I think with the mileage being so low and only a year out of warranty that this type of problem should not happen.

We have had this vehicle in the shop more than we are driving it. The ticking is the latest. I'm not taking the vehicle to the dealership tomorrow, I hope a regular mechanic can give us more insight into whether we can expect more problems.

Every time I start my vehicle I hear that ticking sound, I don't want anyone else to hear it. I have my truck decked out with 22 inch Rims and things like that. To look that nice and to have that ticking sound coming from it is not a good feeling at all. Please help me.

Every time I crank my Traiblazer it starts ticking like I am carrying around a time bomb. Last night I was standing outside and heard this same noise, I turned to make sure my Trailblazer wasn't being stolen. What I found was another trailblazer coming down the road. What is this sound? I did take it in and was told it was normal. Now it is much louder and almost does it constantly. I know there is 2 out there doing it, are there more? The looks I am getting are starting to scare me. Please HELP.

Trailblazer LT 4.2L V6
ok the ticking isn't due to the clutch fan being broke. the clutch fan is a separate problem that sucks. i've replaced it twice in a year and a half. it blows when you get on the truck a little especially if you go over 80mph and get up to 80 fast a couple of times. you can get the part at your local parts dealer from $175-280 and the local mechanic can fix it for whatever their hourly rate is cuz it doesn't take long to fix. the ticking is due to poor lifters. its a lifter tap and they all have after certain points. mine started at 43,000 miles. i was told switching to synthetic oil helps alot. but the engines are just poorly made. on one year of the trailblazer the engine is a recall that should say something right there. also the fan is loud. its because the fan is to small there is to much power pushing it and causes them to sound loud and blow too. the high idle is usually a sign of needing a clutch fan. all in all the trailblazer is a good truck that tows nice and gets decent gas mileage, it has some problems like most other cars. mostly the clutch fan and the ticking noise.
