Ok. I replaced the t-stat, and I'm going to replace the radiator cap in a few minutes. Car USED to run hot into the RED. Replaced the coolant temp sensor and now the fans come on a LITTLE earlier and now the car runs hot but NOT into the red, but CLOSE. After I shut the car down, I can hear the bubbling from the pressure in the top hose especially near t-stat. Im thinkin of trying 1 more stat??

Also I pulled the KOEO codes and got the following: 23, 14, 41, 42 & 63. With the KOER i got: 23, 73 & 76 What is needed to be done?

Try cleaning out the port in the intake that points toward the driver side strut tower.

Clean it out with what? And isn't there 2 ports facing the DS? And what exactly will that do?

I should have been more clear........ the water passage in the intake. They plug up and limit coolant flow past the ECT causing it to read cooler.

Jeff, are you talking about right there where the coolant temp sensor is in the lower intake? If so how do I clean it? I hope I dont have to take the lower intake off...

It is a fitting near the very bottom on the lower intake, driver's side, that a hose fits on. The fitting points toward the driver's inner fender. That U shaped hose goes toward the back of the engine to the line coming from the heater core. See http://www.turbotbird.com/FAQpage/cooling1.jpg

You can get to it from underneath, maybe from on top. Take the hose off and run a thin screw driver up into the fitting to break the crud up. Flush it out. This is an excellent chance to change all those hoes on that side if they haven't been done. They can be done from underneath and you can use those pre formed, cut to fit heater hoses listed in the Part # forum. And Honest, it is easier than doing a heater core Big Grin

Ugh...that look tedious....oh well. Pete, do I need to drain the coolant system to do that? And do I need to change that sensor? How do I flush out? Hey, I just noticed that my fan wiring is a hack job. Looks like the previous owner tried to install a switch for the fans, but apparently does not work. Damn fans only come on when the car get HOT.

AhHHHHHHH......thing STILLS run hot cuz the fan doesnt come on when its supposed to. I'm thinkin I'm gonna have to install a manual switch but the article in the FAQ is either unclear to me or I'm a complete idiot to electronics. I cleaned out the passage (i think i did) on the underside of the intake and on the topside. Could it be the hoses that lead to these places?
