Most of the car dealers recommend to perform Maintenance services scheduled at 30K, 50K, 90K and so on.
At 30K they mostly inspect all the systems, and replace fuel filter.
At 60K they inspect systems and flush must of the fluids, transmission oil and filter, coolant, brake fluid, differential and transfer case fluid, and replace the air filter. Some replace the spark plus at 60K some at 100K.
At 90K all timing belts are replaced, and the status of the timing chain checked. A deviation of more than 5 degree means, there it is the time ayes on the timing chain.
At the Owners manual for 2005 Chevrolet Trailblazer recommend:
Inspect all the systems at 25K, and replace fuel filter.
Replace engine air cleaner filter, automatic transmission fluid, automatic transfer case fluid every 50K.
Replace spark plugs every 100K.
Maintenance Services for your car are scheduled at 25K, 50K, 75K,100K and so on. All are tune ups but they are not the same.
The only concern for GM is the GM Dex-Cool antifreeze. There are some complaints regarding this product. I recommend to flush the cooling system every 50K to 60K.

Sounds like your water pump is going out or your thermostat is stuck. Check the thermostat first and make sure it is not frozen in the clsed position.

SOURCE: ok, i have a 2005 chevy aveo and i ould like to

NOW. These cars are notorious for timing belts snapping and GM has advised to replace at 60K. I have this car and it has an interference engine, meaning that if the belt snaps there is a good chance the engine's pistons will bend the intake/exhaust valves, meaning you would have to have the engine rebuilt if this happens.

I am about to have mine changed, along with the water pump and tensioner since the water pump should be replaced before 100,000 and involves the same labor. I've found that at a Chevy dealership the whole package ranges from $500-$800 depending on who you call.

SOURCE: 2005 Trailblazer Ext: how doi fix a gas gauge on my chevy trailblazer 20...

Common problem on the 03-06 Trailblazer instrument clusters for the fuel gauge to go out. It's usually caused by one of two main problems, either the stepper motor on the cluster's circuit board is going out or the sending unit on the fuel pump is going out. Check out this blog post about the problem - Trailblazer fuel gauge problems

SOURCE: does my 2005 chevy trailblazer need a transmission

The rule of thumb for a transmission service is every 50-60k miles, unless you have something wrong.

The mechanic says the antifreeze is disappearing on my 2005 Chevy Trailblazer. He doesn't see any leaks on radiator. It has 100,000 miles on it.


Antifreeze doesn't just disappear. If it is not leaking from hoses or radiator or reservoir that usually means it is being lost in the engine block. This could indicate bad seals. This also will cause rust and corrosion throughout the exhaust system, including the catalytic and muffler.

Why wont my 2005 chevy trailblazer run correctly after a battery change?


Because the computer was reset after battery change, and you probably need to have the throttle body cleaned. It grimes up often and needs to be cleaned every 10 - 15K miles.

My chevy has about 98000 miles. When is tune up recommended.what is involved in the tune up?


what engine? The fuel filter is in the fuel tank, Spark plugs should be replaced, throttle body cleaned, and the truck generally checked over, battery , belts, brakes, tires ect. Spark plugs, trans fluid, filter, transfer case fluid change, are all due at 100k. You should have the 100K service done. Of course they base that on if you have been following the service schedule. Your owners manual will list all things that are due.

Im in the process of buying a 2005 Chevy Trailblazer, it's beautiful and from the outer and inner apperance it's very well taken care of.. The problem is it has 140,000+ miles.. When I mention...


That really depends on the quality and quantity of maintenance done on the vehicle. With 140+K miles your looking at 20 - 23K miles per year. Does the owner have service records, were all the manufacturer's recommended maintenance done at the proper intervals. Has the transfer case fluid been changed every 50K miles? Front and rear differential fluids at 100K? Any transmission service work done? Plugs should have been changed at around 100K.

I own a 05' chevy trailblazer w/127,000miles when will I need a tune-up?


A tune up is based on a couple things.Number one, is when the dealer wants to pay his lease. Meaning you can go to almost any dealer or mechanical shop and they of course want to make money like we all do. What i do, and suggest to others is , always have your oil changed every 3 to 4 thousand miles, oil filter, fuel filter, air filter as needed.Injectors cleaned every about 20 thousand miles. As far as a tune up, with all just mentioned with new plugs once a year depending on your mileage you put on it and if it is mostly town or freeway. Bottom like is this, make sure you keep up on your oil changes, and all filters, plugs maybe once a year( you can do those yourself, just make sure when you take out plugs and put new ones in there gaped right. Keep all fluids up, oil, antifreeze, break fluids. About 50 thousand miles, you have transmission and rear end fluids checked and filled or replaced as needed, and of course chassis lubed. There is no real way to determine a so called tune up, it is a matter of how well you maintained the car with the oil changes and common sense. I hope this helps. Mike from Fixya

My 2002 trailblazer was missing, so I took it to the shop. They put a tune-up on it, but it is still missing. They said I need a timing chain, truck has 110,000 miles.


Timing chain usually does not cause a miss. It may run sluggish or even backfire, but a miss is like a spark plug with the wire off. Like a dead cylinder. Chevy timing chains do stretch but those engines can handle quite abit of timing. I had one with 120K miles and it was only off 4 degrees. That's nothing for chevy to handle. A tune up is usually nothing but a set of plugs and a hook up to a diagnostic machine. I would look deeper. Go out at night, start the engine with the hood open. Make sure you are in a very dark place. Look for sparks jumping from plug wire. Another way to to use a spray bottle of water. Spray a very fine mist of water around the wires. If they are bad, a spark will jump. Check cap for deposits. You can only hope that the plugs were gapped right.
Good luck
