Heater hose
I am in the process of trying to figure out the route of the heater hoses on my truck.It,s a 90 ranger with a 2.3 engine. My question is does it matter which side of the heater core they hook up too because i am having heat issues. I just changed the thermastat and the heater core was changed a couple of months ago. I think my issues could be a bad heater core.

On my 90’ 2.3l we have had the same problem. It only happens when the outside air temp drops way off the scale. We fixed the problem with a piece of cardboard. My dad would cover the whole radiator with the card board, and I with ½ to ¾ of coverage. In the hard cold snaps the power plant just would not make enough heat. The cardboard would not cause an over heating problem running around a small town, but a highway trip or towing is a different story. We lived in northern Michigan when we experienced the problem. Now that I live in central Utah I have not ever noticed the problem, but the winters are very mild in comparison. We have replaced the T-stat many times and even replaced the radiator once. Hope it helps, Da’Moose
