  1. 2.3L ('02-'11) 2003 Mazda B2300/Ranger Clone - Takes Forever to Warm And Hold Temp

    I asked this same question over on "The Ranger Forum" but it's not getting any response. That forum seems to be slowing down quite a bit over the past year or so. Seems like it's only the same 1 or 2 people ever chiming in with help. So here's my question: 2003 Mazda B2300/Ranger clone -...

    Thermostat jiggle valve 4.0l OHV

    Hello All, I’m doing an intake manifold gasket replacement on this 4.0l OHV 93 ranger. I’ve ordered a mahle intake gasket set. Anyway, the stat thermostat I’ve ordered doesn’t have a built in jiggle valve like the installed stat valve. Should I drill a small hole in my new one, or attempt to...
  3. Need some help with my heating.

    I have a 1995 Ford Ranger, 2.3L from Florida. The truck runs great, but I moved to Ohio last fall where it's a big colder. Before the truck came here the heating had never been used. So last year the heat didn't work and I did a bunch of diagnostics on it to get it working. Last year I...
  4. Inconsistent Coolant Temperature

    Not sure if the old signature I made a couple years ago will show, so I'll start with the specs. 2000 Ranger 2.5L I4 Lima Engine I replaced the thermostat and thermostat housing (that includes temp sensors) about a year ago with OEM Motorcraft parts. I noticed the winter after that, that the...

    Hi guys I've spent hours scanning through the entirety of the internet to find someone with a similar problem, but no one seems to have this issue with these specific symptoms.

  8. Truck Overheated - Now What?

    My 1998 Ranger, 4.0 L, 4-Door, 4x4 recently overheated - the Check Engine light came on, but the temperature warning did not. I was on the freeway, turned on the heater and slowed down. The temperature instantly went down (not quite to normal temp), but a few miles later the temperature went...
  9. Erratic Temp Gauge help

    So I just recently noticed something strange with my '97 Ford Ranger. While driving home from work on the highway the other day, my temp gauge needle rose all the way to the red and the warning Check Gauge light came on. The instant the light came on the gauge went back down to the normal...

  11. Engine won't maintain temperature (too cold)

    I'm no stranger to a stuck thermostat. I've changed one in the past soon after purchasing my truck because the engine would not heat up. As this current winter settled in I noticed the same problem. Naturally I thought the thermostat was stuck so I checked and sure enough it was. The problem is...

    2000 4cyl 2.5 ranger temp gauge always at or below cold barely any heat coming out of vents engine warning light is on... Autozone says the code is low temp reading so, I'm thinking the thermostat is just stuck open. But... I only see 1 bolt on right hand side as I'm looking at the housing...

    Currently my 2001 Ranger 2.3L has had some trouble with the heater temperature.
