SOURCE: 97 GMC Safari - best type thermostat, location, temp?

The owners manual will tell you the temp you should use, but you can also look at the old one when you pull it out as it will have the value stamped on it. As for the brand, most are all okay. I use stant brand since that's what the local parts store carries. To find the thermostat under the hood, follow the top radiator hose to the engine block and a domed housing. It's under the housing.

SOURCE: orifice tube location on a 1998 gmc jimmy

Follow the smaller diameter high side line till you see a spot where there are dimples pushed in. These are the stops for the orifice so it doesn't get pushed too far in. They are usually at the front where the line goes to the radiator/condenser area.

The AC orifice tube is located in one of the metal portions of your hoses. It may be identified by about a few inches from the nut you shall see four small indentations around the surface of the tube. This filter is located inside the tube and usually needs a special extractor to remove.

Location of A/C orifice tube in a 97 safari ? It's not in the bottom line that is attached to the evaporator.

Orifice tube is normally on the end of the a/c condensor but why are you asking, do you think its pluged, if it is pluged then you would see ice build up on that place. Reply.

The front A/C blows cold but the back A/C is not. the condenser is not even getting cold

The rear ac has an orifice tube. This restricts the flow of freon.if orifice tube is blown through or the little screen is plugged with compressor debris it will not work correctly. Some ac systems use a expansion valve same purpose but the little valve can get stuck open and just allow freon to flow through.
