I think you are describing part of the AC system, as it has a silver canister on the passenger side with lines that run to the AC compressor on the drivers side near the oil filler tube. What happens when you run the AC, does it blow cold? Does it still make noise if you turn the HVAC off? If it's the AC system, it's okay to drive.
Just to be safe though. With the engine cool, remove the radiator cap. What is the coolant level? Is it visible?
The coolant reservoir tank has hot and cold marks on the drivers side. The cold mark is roughly the same level as where the hose from the radiator connects to it, so the normal cold level is quite low.

No im sure its not the ac. I had that fixed In Las vegas. Its some line Hooked up to a small radiator In front of the main radiator. It travels back to the rear goes under the motor oil spout. It has some kinda silver tank attached to it. I would run the van and the motor temp guage would go up and down. As long as im on the road going steady its fine. but when im stoped it would go up and down. But ill do my best to get a picture. Thanks agian for the responce.

that small radiator you're referring to is either the evaporator for the a/c system or possibly a trans cooler. i would say the evap since most stock trans coolers are built into the main radiator.

![Question](https://chevroletforum.com/forum/images/icons/icon5.gif)
I know that there are two silver tanks in the engine bay that are visable. the large silver tank is for the a/c which i know. That one is on the right when your standing in front of the van. But there is a small on one on the left. So your saying thats Part of the a/c aswell? My question is that is that normal for it to make a hissing noise, and for the temp guage yo go up and down? Is it safe to drive like maybe to tahoe and not brake down on me. the engine is still running fine. Ty ihatemybike.. This is a 2001 chevy astro van 4.3..

No heat usual mean low coolant. The fluctuation in engine temps concerns me. I really want you to check the coolant in the radiator.
Is the HVAC blower still working?
The hissing AC is probably a line leak after the compressor.
When is your trip?
PM me for my phone #, if you need quicker help.
