overheating st Options

[Malhar95]

i recently noticed, that my gauge reads hot sometimes and then drops quickly, first time it did that i checked the coolant, was a little low added water,

and then it does it randomly, coolants level is good. however when i turn the blower on (with temp to hot and AC button on) the needle comes down.


i also noticed the first day, that its leaking from where the bottom radiator hose connects to the engine, above the transmission area.
but yesterday when i was filling up gas, (it wasnt over heating or anything, i just checked) i saw its not leaking from there, but its quit wet under the coolant reservior and it was bubbling.

im guessing its the thermostat, but any input from you guys? how do i diagnose a thermostat, other than taking it out and puting it in a hot pan?

I had this very same problem but mines a 5sfe. I swapped out almost the whole cooling system but still having the problem. I'd recommend you use a infrared thermal scanner thingy. The laser thermal thing. Lol. Sorry don't know the name of the tool. But yea use that to determine how hot the engine block is, upper rad hose, bottom rad hose, and the rad. Make sure they're reading at the right temperature. The reason I said that was because when I had this problem. I took it into a shop and they told me I have a really good cooling system in my car. Looked at them crazy and they said I had a faulty ECT sensor(the dash one). So it was "lying" to my dash that it was overheating when it wasn't. So in other words. Check your electrical components too.
