I have a 1999 Mazda B2500 that is overheating while idling or when the air is on. Just started hitting 104 days here in Texas so I'm sure that isn't helping the situation.
When driving the temp meter is at 50% but when sitting idle the temperature steadily climbs to the red line. I can bring it down by shutting off the air and giving it gas in neutral.
- When I first noticed the problem, the coolant well was dry (I know...just had a baby so I've been a little off my game)
- The fan is mechanical I believe and appears to be running fine.
- The upper radiator hose is firm
- The valve on the radiator cap has some brown residue/liquid dried as if released around it
I'm a novice but can like to do my own repairs. Any advice on where to start diagnosing what is wrong? Should I attempt to flush it or is that mute at this point?
