Also i noticed, the car runs hotter when theres alot of electrical load on, IE lights on and sub cranked up... Maybe the limit of the alternator is effecting the temp/fan sensors signals?
Ive got a Radtec FMIC, Airtec rad and turbo cooler!
Hi Rogey!!
I´ve got same problem mate!!
I thought it was the old radiator but after fitting new Airtec radiator the past weekend the car run hot on highway, not on the town. I think it is due my Airtec front mount intercooler, restricting airflow to the radiator......
Did you test the MSD fan switch? Where sit the water temp needle running on town and on the motorway?
I´ve got a auxiliary digital water temp gauge and it reads 100º celsius running on motorway (Dash water needle sits on "R") and 94ºcelsius on town (Dash water needle sits low, between white and "M") and the fans never cut off.
I think my dash water sensor is fucked too.....
Also I changed the wiring installation of Fans and now the water temp needle sits in same place after turn on the lights, before renewed installation needle moved up a bit after turn on the lights......Maybe this could answer your last question.....Drop voltage effecting water sensor due a poor and old wiring fans intallation.
Mate, don´t forget to send me the pics of the spares we were talk about in the P.Ms
