Water Pump Problems of Chevrolet Trailblazer

The vehicle was purchased new in 2004. Since that time the water pump has been replaced twice yielding a total of three water pumps. As of this writing the vehicle has been solely used for private use not commercial use. We currently have 85,000 miles on it. Three water pumps in 85000 miles is wrong as there is no longevity to the part. The problem was noticed in motion and could have caused severe engine/transmission damage if not stopped iimmeadiately.

I have had problems with the fan clutch and water pump. I've replaced the fan clutch twice and the water pump once. The water pump has gone out again and I still have the roaring and ticking from the fan clutch.

I was traveling on the highway when I herd a rattling sound coming from the engine, got off the highway and pull into a station. Call the tow company to tow it to my mechanic he said the water pump bearings broke and the fan stop turning since both are connected together, he said the engine might be damage possible due to overheating. There was no warning of over heating on the gage, water did not leak from the pump. I call gm and they told me to tow it to the dealer for diagnose and they were consider my claim after the diagnose check; they knew my warranty just expired in July. I told them there was know warning of any kind everything was find water pump bearings just broke along with the fan clutch this sample problem cause the whole engine to go bad. If there is going to be a problem with bearings broken on the water pump there should be a warning of this potential problem. Right know I need help to get my truck fix gm denied my case to fix the engine. I believe gm knows there is a problem with these water pumps and serious damage it can cause if they fail.

I just want to get some information out there on my experience: battery replacement seem ways too often 8/2008, 10/2010, 9/2013 - and there is no notice until you cannot start it one day. First thing to go was the idle pulley. I have had the water pump/thermostat/belts replaced multiple times 50k, 60k, 87k. Headlights and tail lights replaced at least 3 times each. I have had to clean the throttle block plate multiple times or the tb will stall when the brake is applied or heat/ac on. I have come to find out that there are many non-oem parts which I never replaced (I purchased used w/17k miles) and nothing showed up on car fax or other reports about accidents or repairs. I had the gas guage/tank/float repaired while it was under warranty still and then a year later it broke again, and I am still riding with it broken (at least the last 5 years), which of course keeps my check engine light on nearly all the time. I just located the notice that gm is now doing 100% of the repair and I will be making an appointment to get it fixed as I will not pass inspection and I never know how much gas I have. I fill every 200 miles. There are other minor issues such as interior lights going out, both of the front seats have detached from the side molding (only 1 little screw holds them in), the rear washer has not worked in about 6 years. I also have loud noises coming out of the tires/wheels and no one can determine an exact cause, but it's not the brakes or rotors or anything like that. I currently have under 89k miles. I am waiting for the door electrical system to go next as that seems like what is next on the list of tb issues.
