Ok I have a question I've been searchin for the answer that I found part of this morning. My car is a 1988 S4 Vert which I've finished my swap twice first time was a JDM S5 swap that blew apex seal in fron housing due to no FCD at 7000 rpm. Now I'm running A S4 monster ported TII engine, Microtech LTX-8 waiting for the rest of my turbo set up. I put in my God Speed Project radiator a few weeks ago and e-fan. Yesterday was the first day of me driving the car in weeks. The car was acting like it was over heating where it shut off and the e-fan came on. The radiator does not have the temp sensor on the bottom of the radiator, Which up to this point I now believe is the problem. How to I bypass that signal so it will stop over heating, bucking surging and shutting off with in 5 miles of driving.

This is what the radiator looks like as you can see no Water temp sensor at the bottom of the radiator. This is what I need help from Hailers posted on Hozzmans post about grounding of something but I need to know exactly how to do it.

 

i just installed one of these on my s5 vert. i left off the fan shroud for the first drive because it had to be cut to fit it got hot very quickly. i put the fan shroud back on and rebled the system and havnt had any problems since.

 

I have a S4 not a S5. What is the extreme symptoms of a bad Thermo Water Sensor behind the water pump???
