I been asking around here about this but here is the latest:
87 Ford Ranger 2.9 liter V6. Engine rebuilt 3000 miles ago by previous owner.
When I first got it, I noticed it would run warm at times (about 3/4 on the gague). Or at the "O" to the "n" . No numbers. I replaced all the hoses (they were original) flushed the coolant and replaced the thermostat.
Occasionally I always got a whiff of antifreeze which I assumed may have been a leaky heater hose which is now replaced but I spillled antifreeze. For 2 weeks, all seemed well.
Tonight on the way home, the truck heated up to almost the "n" about 3/'4 of the way up and fluctuated. It didnt actually overheat but I stopped from time to time and let it cool. I commute 67 miles each way.
Another observation is my defroster doesnt seem to work well. The windows inside fogged up. Someone said that could mean heater core.
I inspected everything and no visible leaks. No smoke.
I checked the collant level and its full.HELP

If the radiator is blocked the truck can run hot because the coolant cant circulate properly.Try flushing it

It's either a bad heater core, or the valve inside your engine (located between two heater hoses) is not opening and closing correctly. If you really are smelling antifreeze, and the windows are fogged up, then 99% of the time, you have a leak in your heater core. The only thing you can do is to have it replaced.
I urge you to feel the carpet on the front passenger side of the car. If it's wet (from antifreeze), then it's definately the heater core.

Before you spend more money try to find the coolant leak first. A leak will not allow the cooling system to hold the constant proper temp no matter how many parts you replace-PERIOD ! If you smell coolant track it to it's source. Dry up any residue and look for reoccuring wetness. If you cant find a exterior leak -pull the spark plugs and look for a really clean one(or more) could be a cracked head or blown gasket. If no luck there look for moisture in the oil- they could have put in a used engine with a cracked block.

A bad water-pump would cause the engine to overheat. The water pump has a "weep hole" which allows a bit of your anti-freeze to leak out, which could account for the smell of anti-freeze. If the heater core is bad, you might notice the passenger side of the floor being wet, and/or, when the defogger is on, sticky substance might get on the wind-shield.

Go the www.therangerstation.com, and in the fourms section there is a section for that engine, there has been posts about everything, I would start there to see if you can find a patrun.
