Usually the cause is from over heating.. unfortunatly the only remedy is to really watch your vehicles temp and keep the systems maintained.

My 2007 chevy avalache wont blow heat or air what could be the problem?

The Blower motor could be bad. Up under the dash on the passenger side. Probably under a cover of some kind. You can try hitting it (lightly) with your hand.

Water in front differential

The water in the front differential is caused by driving through high water. There is a vent at the top that allows for the expansion of oil without building up air pressure. You are going to need to replace the front fluid and repack the bearings to prevent further damage. It is also recommended to install a vent tube to prevent it from happening again.

How do you replace the fuel pump relay after you have installed a new fuel pump on a 2002 Chevrolet Avalache?

the fuel pump relay is located in the underhood fuse box. but it is not required to replace if it is defective then was probably the problem all along

Nissan navara 2006 blown hole no1 piston 16000kms

I'm sorry to hear that!
When you get it fixed get your injectors serviced as holes in pistons are usually caused by pre-ignition ( pinking ) or running too lean.
If the injectors were left wet ( can happen if a blown head gasket was the cause of the first rebuild ie water in the bore ) , or dirty , they may not be delivering enough fuel causing the top of the piston to get too hot and melting a hole in it.
Option 2 , the timing was set wrong, ( too far advanced ) causing pre-ignition and ending in the same way.
Good luck with the rebuild.

My 2000 chevrolet impala exploded when i tried to crank it part from the motor was all over the yard, what do you think happened and why

probably had leaking head gaskets. water leaks onto the piston when it sets. when you go and try to start it the piston tries to compress the water. you cant compress water so the motor blew. usually that is what causes this.

2005 Chevy Avalache

your catalyctic converter is simply a pollution filter in your exhaust line, it could possibly maybe be your problem if it is blocked over with carbon just remove it and check for a carbon build up, its rare tho for it to cause the car to sputter

2002 MDX, dealer is recommending a new t belt. Is this really needed.

if the timing belt breaks while driving serious damage can happen resulting in bent valves and busted pistons. most makers reccomend replacements at 70K to 100K. your owners manual should tell you. be sure that you have them replace any othe items that are exposed and readily accessable. ie water pump and so on, to prevent further work later at more expence

V6 engine failure

if heads were warped, then yes coolant got into the cylinder/s . so there is your water poured into engine. a bent piston rod cannot be diagnosed, it must be seen. a would run slick 50 into this engine.
