I have a 99 blazer. One of the hoses is pissing fluid. Need advice and steps to change one or all the hoses. How to get access? So damned right under the hood! Thanks in advance!

 

Plenty of room if you remove the air filter housing, you can get right at the hose connections.

 

+1
the air filter housing only has one 10mm nut and a hose clamp. everything else is pressure fit. just pull on it firmly after you remove the nut.

 

those ones on the gear box are usually very rusted, spray rust buster on them. or since you are replacing it anyways you can just cut the line close the the nut part and then use a socket with extension to help you get it off.

 

^^ Good point and great idea!
