Excess cab heat
What do you all think of installing valves in the heater hoses to shut off water to the heater core?
Background - in the 16 years I've owned this truck (95 w/I-6 & 5 spd), it has always run hot in the summer (just above normal on the temp gauge), cold in the winter (just below normal). Flushing every 2 years is a given. I've replaced just about everything. Water pump, a new thermostat every year with varying ranges, heater core & hoses. I even put in a dual core radiator a couple of years back. Don't know what idiot at Ford decided a single core w/ the AC heat exchanger in front of it was adequate for Texas summers. But the dual core hasn't seemed to effect the temp readings any. I even replaced the temp sending unit & gauge thinking that might be bad. Nothing helps.
I've never used the AC because of the huge hit on my mileage. I just keep the compressor there & lubed to keep tension on the belt.
But even on a warm day, the heat coming from the heater core will flat drive ya outta the truck! I'm down to shutting off the water to the heater core in the spring.
Any thoughts?

I've often wondered the same thing. I also get a lot of heat of my trans and road through the floor of the truck (i don't have any insulation on the floor right now.) but i notice i'll be hot in the truck, get out to fill up on gas, and when i get back in to the truck the cab is almost unbearable.
It's a Canadian thing eh!

I just crack open the side vent windows while driving, usually beats my A/C any day, but turning on the heat in the truck also helps dissipate the heat from the engine. Try closing the vents with the heat on and should feel like normal.

Just unplug the two core hoses on the firewall and put them together, bypassing the heater core cheaper than valves and the Coolant has to go in one side and out the other for the flow

To answer your original question, I would put a crossover with valves in both lines and one in the crossover.
