If the temperature reduces as vehicle speed increases, that is a good indication that air flow across the radiator is affected in some way. 4).

Hi All:this kind of scenario.1). Coolant level low - check the overflow tank 2). Air in the system - well documented recently 3). Inoperable/malfunctioning fans - resistor pack discussion well documented recently and in archives. 4). Bad gauge - smack the dashboard a couple times above the speedo. Something's up - this engine never ever gets hot if all of the above are working. Just a high reading isn't a big deal, if the fans are roaring outside. Check them with and without the a/c on. is the red light blinking on the dash? Scott |
My experience with "the bad gauge" was that when it malfunctioned,My experience was just the opposite. The first clue I had that my first attempt at the voltage regulator fix didn't work was that the temp gauge began to read hot. Once I did the fix again, the temp gauge stayed right in the middle. Voltage Regulator fix: BTW, instead of reusing the screw, I put a micro bolt through the hole in the VR, through the hole in the cluster case (which had cracks around it), and secured it from the back with a nut and LockTite. The intent was to prevent the VR and the metal heat sink from vibrating and ruining the contacts. So far so good. Joe |

I just fixed my temp gauge yesterday night. It was not working at all before, today it is indicating "HOT" I mean by hot the gauge goes to the last mark before the end on the top. What could be wrong ? Is it possible to mess up the voltage regulator, although I don't think that I was too close while soldering it. Thanks Christian ----- Original Message -----

My personal experience (having the done the "fix" more than once) is that, if the VR problem is occurring, both the temp gauge and fuel gauge malfunction together. So, if your fuel gauge also is reading incorrectly, you may want to re-do the VR fix. If only the temp gauge is in question, is your engine in fact overheating? Are the fans running full blast? If it appears that your temp gauge is reading incorrectly, the problem may be the sender plug (about $35) located on a flange at the front of the engine. Previous posts describe this item and its location (I recall that there are two sender plugs on the flange). Can a voltage regulator be ruined by solder gun heat? I have wondered that myself when doing the fix. Steve at Europarts San Diego sells the VR, so they must go bad from time to time, but I will leave it for greater minds to say. Joe |

JC,
Need more info, so the temp gauge just started showing this? Is it happening in city driving? Towing? in hot weather only? Is your coolant level low? what happens when you run the heater when its at 230? Do you know if the fans work? ... Jerry --- In ev_update@y..., ieworld@y... wrote: Hi All:this kind of scenario. |

Are both fans running? If not, see previous posts. Also check to see that

Hi Jerry,
Fans are working and is roaring load. This happens during city drive. I am not towing anything and the coolant level is in Max. I have not turn on my heater and when it hits 230 my A/C is not turn on. This puzzles me a lot. There is no engine leak that I know of. I will looking to this tommorow and will post later tommorow any results. Thanks.

Those fans won't push much air if the louvers have failed closed. Can you

Yes, the engine has a thermostat.....an old-fashioned bi-metallic type

mounted on the front of the block behind a cast hose fitting between the 1st and 2nd cylinder, or thereabouts. If the thermostat was blocked closed then yes the engine would be hot but the fans would NOT be running because no hot water would be circulating through the radiator and that means there would be no hot water to heat the thermo switch that turns on the fans. ---------- From: "IronWood Designs" <zawalick@...> To: <ev_update@...> Subject: RE: [ev_update] Overheating - HELP !!
