Engine won’t get up to temp.

Hi!
So I bought this 96 Vectra Grand Tour. It is in beautiful condition with les than 100k on it (Diesel Pusher) I am having a problem getting the engine up to temperature. I live in Alaska and like the front heater to work while driving. I am hoping someone has had this issue as well and has fixed it. Thanks in advance!

There are usually a couple of shut off valves underneath the rv that shut off coolant to the front. Are you sure those are not off for some reason

I did see a valve that was closed!!! I will open it!! The hose was disconnected but there. Thanks!

Hose or heater core might be bad and previous owner just closed the valve over replacing it.

You have a gas unit . . . I was thinking diesel . .. Sorry

So the valve is leaky and the hose is rotted in a few areas. I am fixing it this weekend. I hope it is just the hoses.
