Wrecked my 2003 chevy astro van and am fixing myself......need to find some free schematics of the front end

Could be that you need to add a lil more fluid to it.

The EGR Valve is located on the front of the Engine under the frest air tube. It is at a 45' angle. When checking look for lodged carbon chunks. I recommend using a gesket with a screen built in. It is located infront of the Thermostat housing.

you either have bad brake pads or the bolts are loose that hold the front steering suspension on.

Find one at a wrecking yard.

Replace the complete heater control vacuum line over the motor with rubber vacuum tubing.
The heater vacuum line connects on the drivers side of the engine halfway back on the intake manifold.Run the new line to the heater vac connection at the passenger side at the right front in the engine compartment.
I change 2 a week....this should be where your problem is.

when you turn on ac look for front ac clucth to be turning. if it is feel the lines up to the cowl if they are cold 40 degrees or so theres probably enough charge with the year of that vehicle it maybe low on charge ac systems will usally hold for at least 5 years.

sounds like a possible wheel bearing issue or brake pad issue!!! i would definatly have this looked at, but in the meantime, make sure that it isnt just a backing plate contacting the rotor ...hope this was helpful!!

some of them are dummies they are not vacuums,but if it is a vacuum line is it color coded?

One quick call to the , or a wrecking yard and ask them, would be all you need. They do them all the time. We always removed grille assy & came out through front, but that was a few years back since I've done one of those, so things may have changed. They'll tell you from experience.

are you try to remove the tapered end that connected to the steering linkage ? if you are you will need a pickle fork, some part stores will rent this tool to you good luck kdc744
