The delays in getting this engine fired is frustrating. Family issues are a priority, but I am not working at this project hard enough. .... I think old age makes me lazy!
Yesterday I was trying to figure out all the connections in the wire harness and discovered the wire to the Coolant Temp Sensor connector was broken. It was only holding with 1 copper strand - don't know why Toyota could not have made the wire gauge just a tad bigger?
After finding zero aftermarket options, I emailed Jerry at 22RE Performance, and he instantly replied - gotta love that extraordinary customer service!! - there is NO connector and NO wire harnesses are available.
He suggested taking the contact out of the plastic body to solder a new wire. I looked at it carefully and decided trying remove the metal contact would most likely destroy the very crytalized plastic housing and break the thin metal contact.
So I took a very sharp knife, and VERY carefully scraped off the 30 year old insulation around the end of the broken wire. I soldered on a new wire, and had to drilled a larger hole in the little black seal cap to avoid pushing hard against the metal contact tab as I slid it down the wire and into the connector, and only inserted it partially into the top of connector body - I didn't want to break the little metal contact tab that the wire was connected to. I used some Ultra Black to seal it back up.
I will slip some heat shrink tubing on the wire and solder the pigtail onto the broken wire harness wire.
This is one of the main reasons why I decided to do this rebuild myself.... God only knows what a "shop" would have done with this part??
The question is, do You know what that sensor is and what it does?
I challenge you Gnarls.....
Don't disappoint me, And be careful its not what you think it is. (Hint)
Mine has been deleted. (Hint) If it came in to the Chevron I would have explained what it is, what it does, and your options.
"Extra credit" If you explain how that system works and what it affects.
(Best of Luck)
