I have 2004 gmc 2500HD and this morning I went to check my antifreeze and when I took the cap off there was a ton of pressure (the truck sat in garage all night).I have never had this on any other vehicle just wondering if something might be wrong.Top radiator hose was pretty firm but not so much I coundnt squeeze it a little.Is this normal or should I worry.Thanks.
