any help would be appreciated
You probably have a leak and or low on coolant. If your cooant level is okay and you don't see any leaks, jack up the front end as high as you can and run it with the cap off. Give it a couple of "whomba" "whomba" with the throtle then look down the filler neck and check for bubbles rising to the top. It's best to pressure check the system first. Most shops do that for free.you might have an air pocket in the system. This may sound stupid but I've had to jack up the front of the car and then open the rad cap and burp the system.
