  1. I generally run 55-60 mph on the level, and that will get me around 15 mpg with intermittent AC use and a blanket hung behind the seats to reduce the cooling area. Uphill, or into a headwind, you take what you can get, minding the heat level and so on, and I don't use AC on uphills. Some times I can take hills at 45 or so, but some of them slow me down farther, seldom below 35. You may lead the parade uphill, but most people are fairly good about it. YMMV, literally and figuratively.
  2. Just to close the loop: I bought the CSF 2057 radiator Linda suggested to Sherrie, and a Toyota thermostat. I don't know which of these did the trick, but I'm now running at a better temp, about a half inch from the red line after a long uphill with AC on. Thanks to all for suggestions along the way. Obviously, I have done what people wisely suggest not doing: throwing parts at it. But there is a very limited amount that I am able to do myself, and I'm just relieved that it's running less hot now. This is a great forum - thanks again.
  3. I've been through the mill on this with my '91 Warrior since the fan shattered and took out the radiator and lots of other stuff last July. Had it towed to a shop in Laramie (roadside assistance insurance paid for itself for several years with that one event). They replaced the fan, shroud, fan clutch, radiator - about which I knew nothing other than it was a 3-row - and a couple hoses. Thereafter, it ran up toward too hot at almost any provocation. This year, I didn't want to start out in that same condition. Took it to the shop that does engine work for me. The fan clutch was not engaging th
  4. Dan, there's a photo here that explains which sensor is which: http://www.yotatech.com/f116/coolant-temp-sensors-3vze-224860/index2.html Photo about 2/3 down the page, You can see the unlabeled sending unit lower right.
  5. Wade, just saw this. Very interesting. Hoping to find a page like this for the 3VZE. Thanks!
  6. Hmm. Well, the replacement radiator is a three-row, nothing else about its surface area or other characteristics is obvious to me. If nothing changes with the Toyota thermostat, I guess it's off to the radiator shop.
  7. So I ran the Warrior back out in the heat on an uphill and the temp needle went into that little space between the black and red parts of the scale. Pulled off, used the heat gun in a couple places (best seemed to be pointing it at the place where the temp gauge sender screws in) and the reading was about 240 degrees, as someone on the thread predicted. So, the sender is probably okay. Likely the last thing I can do myself is to get a Toyota thermostat and put that in (a 195-degree Stant was just installed) as a sort of Hail Mary play, in case that makes a difference. Radiator shop after that,
  8. Well, that's the thing. If I get high temp readings (like 240+) I'll assume the sensor and gauge are okay and will look elsewhere. If the temps look normalish despite what the gauge is reporting, I'll change out the sender, and see where that leaves me. I have to get this solved - won't take it on the road like this.
  9. Plenum of some sort? I've seen that name in use. DanAatTheCape, Here's a truly crappy photo I took. I've drawn a red circle around the sending unit: simple flat-blade connector is the one. Amazon has one for sale: http://smile.amazon.com/dp/B000IYZ0KS/ref=wl_it_dp_o_pC_S_ttl?_encoding=UTF8&colid=G7GEGNY01IGE&coliid=I2LVRQEY7H1F3D and they're available about everywhere.
  10. Thanks, Dan. I just found the sensor/sending unit (crowded neighborhood back there) and verified that it's the right one by unplugging it and turning on the already-warm engine: no movement of the gauge until I plugged it back in. I have ordered an IR temperature gun and will do readings at various points after I take it back on the road and get it hot again, and proceed from there. Seems like, if the gauge is accurate, it could be time to visit a specialty radiator place for diagnosis. If it's not, I'll replace the sensor first and see where that gets me. I got it warm enough for the fan
  11. Thanks guys. This will be a lot easier than anything I could have come up with.
  12. Found a source saying the temp at normal operating heat should be 185-195, so I'll use that as a standard.
  13. What should the temperature of the coolant be, or what should it be below? Thanks.
