Radiator blocking and SAFE temperatures!
Okay,
Now that I have a radiator block (Cloud Rider Grill--pricey but nice looking). What temps should I montor on my ScanGuage II? --right now I'm watching Fwt and MeC (which I think is the water temp in degrees F and the Motor Electronics Coolant temp in degrees C), am I missing anything essential? What is SAFE for those temperatures? --does anyone have a tech manual with numbers for it? |
Re: Radiator blocking and SAFE temperatures!
The sticky scanguage thread will provide "some" information for you. 183-185 F is a usual FwT value for me under normal conditions.

Re: Radiator blocking and SAFE temperatures!
When my 2005 was new, the water temp was about 183-184 all the time.
Now, it runs more like 186 to 188 all the time with no block. Not sure why the change. FYI, there is no water temperature probe. Water temp is inferred from the CHT, cylinder head temperature. |
Re: Radiator blocking and SAFE temperatures!
I see anywhere between 171F & ~185F, summer, winter, uphill, downhill or on the flat roads.

Since that loop isn't hooked to the heater core, I'd think in the winter its likely to heat up more with the radiator blocked. How hot can those electronics go? MeC is one of the XGUAGES by the way. Mco and Gco too if they are cooled by the same reservoir. |
Re: Radiator blocking and SAFE temperatures!
Motor Coil and Gen Coil can reach 200-220'C before a MIL lamp lights.
That's like 400'F !!! I don't know how hot the M/E coolent temp can get, but I'm very sure you won't have a problem. |

........ Its a separate system from the Fwt number so its different and its supposed to be a lower temp for the electronics...............
Additionally, doesn't this system go into a limp home mode if the coolant temperature is excessive? My understanding is that the engine can cool itself by selective shutting off fuel to cylinders and using air pumped through the cylinders to provide temporary emergency cooling. |

I don't see how the electronics and engine coolant can be too greatly different in temperature. Aren't they all using the same coolant, recirculating through the same radiator?
