I have a 2005 H2 SUT modified...magnuson supercharger. The serpentine belts break and the rebuilt transmission overheats. The transmission was rebuilt to handle the extra torque, why is this happening? Help me please!!!
This Hummer has 6" lift (Bullet Proof) with 40" tires. The engine also gets hot....is this because of the supercharger? What can I do?
Because I am a girl...mechanics see me coming and I swear they yell "quick, take her money and run" LOL...kidding or not, that is how I feel...they take me for stupid and all I am getting is the run around.

Re: 2005 H2 SUT problems
How often is the belt breaking? excess revolutions can cause premature wear. flushing the cooling system with the proper cleaners, refilling with dexcool and DISTILLED water can reduce the engine temp in h1's by at least 10 degrees in the desert. this i have done. also if the cooler for the transmission has not been upgraded to handle the new trans you will still get an overheat. you can also put a electric fan on the trans cooler. the belt may not be aligned properly.

there should be a decal under the hood somewhere that shows the belt routing. if its gone you can probably go to the library and find a book of your car that will show the routing and you can either draw a picture or take a photo of it.
If the serpentine belt broke, the water pump would have also stopped turning, causing coolant to stop flowing...therefore the heater would run cold. Since the belt also turns the alternator, the charging system would also stop working (alt light). Since nothing is flowing through the engine or radiator, the engine will quickly overheat. Since your engine oil also does a bit of cooling as well as lubrication, oil passing through the overheated block will break down and overheat as well. Hopefully the light came on for that before any internal bearing damage was done. Smoke was due to the overheat. Your serpentine belt likely is not covered under a warranty, especially after four years. Hopefully the problem is isolated to just the belt but I do recommend that if you have an automatic transmission you change the fluid in that even if you are not at the change interval recommended. Trans oil is cooled by the cooling system and a severe overheat can chemically change it. Doing a change now will avoid any overheat related trans failure. Since you can't remove all the trans fluid (at best during a change you only remove half) so I recommend using a bottle of lucas trans additive to bolster the remaining fluid. Good luck!!
is the car low milage ? by taking it for a drive you will be able to tell if everything works and stepping on the brakes lightly you will be able to tell if there is any noise coming from them.. take it on the road and step down on it to see if it accelerates good.. make sure it shifts smooth and there should be no smoke coming from anyhere.. check under the hood to see if it is clean everywhere. this tells you if it has been taken care of .windshield broken? check for chips here also.. interior clean ? this lets us know if its been taken care of also... if its late model and low miles you probably will be ok.. driving it will tell the story about how it is going to run ... holler if you have more..
