Temp jumping
I'm a bit perplexed. My electric temp gauge was reading hot, but not all the time, and not hot enough to be worried, but higher than normal nonetheless. I installed a manual gauge, high quality cheap C. crap, Sunpro, and it is more stationary, but it still seems to go hotter than normal, quicker than normal, and jump around more than usual.
I'm wondering if the blades, the ...impellers of the water pump would be wearing out. Is that possible after only 3 years?

I got one of these and I've never been sorry (and they're dirt cheap anymore too):

It's great for pointing around the engine and seeing the actual temperature.

For $20, I could never understand why I didn't get one long ago. It comes in handy everywhere. Point it at the in and out on a heater core and see if one's cooler. I've used it to check the temp of the floor of the intake, fuel lines, etc. Plus, just pointing it at the thermostat housing tells me if it's working right. Then go into the kitchen and point it at lunch to see if it's done cooking.

I have to admit I really like having a mechanical gauge with the sensor in the block, where Ford put it. I can see every time the thermo opens. I just feel like I have a true account of how the engine is doing, rather than having the sensor in the water neck, and reading the temp of coolant coming out of block. k

I guess it is time to pull the water pump. I am still having the same issue, and am wondering if some of the impellers are missing? Could that happen in under 3 years?
Anyway, just to refresh everyone, I have a new manual gauge in the block, and a new 198 thermostat. I have elec fans too. At a light the temp climbs to 210 and stays until I start to accelerate. Once the engine revs, the temp quickly drops, as though coolant is just not circulating as it should with the pump at idle. Once I'm rolling, and I mean within 60 feet, the temp drops to 185 or so. Fans are working fine.

Heh, that would be a fun one. Although, I may have to get A/C for that! Something I've never really had.
But, I know a bunch of guys waterproof their center consoles in the Broncos since they're so big and roomy inside, and insulate them for beer. I still need to do that...
