I've asked before and got no response. My 1999 Solara SLE V6 auto is missing a plug here... I asked another dude from Solaraguy and he says his has a plug plugged into it. There's no extra plugs in the engine bay and I'm confused as to what this is for. I know it has something to do with the coolant. Thanks for your help!! PLEASE GO CHECK YOUR CARS!

looks like a temp sensor.

Where does yours come from? Can you trace it for me and take a pic?

Anyone else??

looks like a coolant temp sensor to me

ok mine is hooked to the wire loom the cones from the o2 sensor.

Yeah thanks. I'm wondering if it has anything to do with my CEL, PO135 bank 1 sensor 1, oxygen sensor. IF someone does take a pic of where your plug comes from exactly I'll appreciate it.

THANKS SO MUCH!! I'M GOING TO LOOK INTO THIS. For some reason there's no such wire attached to that same harness. I'm going to have to cut open that wire loom and check inside. I do know the engine was messed with (used car) the engine was replaced and such. Anyone know how to get the VIN# off of the engine? I'd like to run a car fax on the engine. (or car it was attached to)

what are thoes clips in red...that one with the arrows looks exaclty the same and i have no clips in that section of my engine bay.

synenergy52 · 02-09-2008, 12:35 AM

I don't know. They plug into the side of the thermostat housing... the one on the side has a skinny prong. Here's a superview of that pic. I cropped and brightened it!!

hmm, that is definatly strange.

looks like someones had an engine replaced. See the silver triangle shaped thing inside the hole on the head (left middle of the picture, there is a big black wire running over it)

That is placed there to let the people who sold the engine know if it has been overheated. Hate to say it, but if the plug is nowhere to be found you might have some wiring to do...

Wow are you serious? Well do you guys know how I can know where the engine came from? Is there a vin# on the block anywhere?
