gauge or sender?
When my blazer warms up to certain point (not always the same) the gauge will immediatly peg to the hot side. It does it mostly when it's warm outside, and no it's not actually getting that hot. But it just jumps way past the hottest reading. Would you guys guess that its a sender or a gauge?

maybe both.. just have the check each of them to find out... i would suggest the sender as it is harder for gauges to go asthey are dependant on the sender for readings

You should be able to test the sender if you can get to it with a VOM. Run a jumper to it and check the resistance as the temp climbs. If the resistance changes slowly without any spikes the sender is good....

I had this same thing happen to me on my 76, and it was the sender...a NEW sender. I had changed out the original one because it wasn't showing any temp at all, and then the new one started pegging out as it would warm up. O'Reilly's gave me a new one, and that fixed the problem.

Something similar also happens on my truck. The coolant temp guage starts out BELOW "COLD" and never (and I mean NEVER) climbs above the Quarter mark. It's a NEW sender too (from Kragens). I think I'm going to order a sender from LMC and try IT. With a 190 t-stat, my truck should at LEAST get to the Half mark.
