    The overheat continues..fan help please !!

    Yea originally had a ported Eaton, at 14 psi had no issues tuned by Kurgan, put on Whipple, hit 18 psi and his tune isn't overly aggressive, no issue at tuning session, would say maybe 6 months later issue started and it wasn't like at a track day, just out of the blue driving one day temp...

    I read this twice, what a great overall thread, info was incredible. My only question was with the Felpro gasket PT # mentioned, is it only usefull for the DC head and how do we know if we have the DC head? You can really see in the HG pic the larger coolant passage, will definitely look at the...

    Reading your post, wondering if it is head gasket, will do ARP studs, but also wondering if T stat relocation is a worth investment?

I trailered the car 6 hours to Injected Engineering and dropped off on a Monday after night in hotel. 8 days later mechanic called, said he drove car about 15 mile loop and car hit 246 degrees in 6th at 60 mph.

    Car was bought NEW in 2003, one owner, had P1SC with stick Mach 1, this had Ported Eaton, no issues, went with Whipple, friends installed, about 6 months later, this all started, there is no longer any part I haven't tried, that's why I am leaning towards since no coolant loss, intake gasket...

    When I first had this issue, I actually had a 3 core aluminum rad (brand new), a Reische 170 T stat (new) and it still did it, but that WAS before I found lower hose kinked and I sold it and went with a new stock rad. I am able to get it to run hot here in the garage since I put in manual...

    I used the Reische method. I figured I would take some out of expansion tank to allow for expansion when hot, but heck I've tried everything else. So, uncap tank and crossover, fill tank to top, then fill crossover till what tank starts to overflow? Cap expansion, then fill crossover, cap and...

    I wanted to add some things may help. I changed plugs, all looked good, no white smoke. I have been using one gallon of 50/50 and plain water and all good. One day out of the blue after a heat cycle, removed crossover plug and coolant was a DARK green, like the color if I was using straight...

    I could be wrong, but my though is fan is in reality 1 speed ( high), and resistor cuts current to run on low, this kit wired directly to fan should do it, all I'm worried about is with fan disconnected from 3 prong and resistor, is pcm gonna be confused when signal doesn't come back that fan is...

    Yes, fan is new, everything works good till hard pull..kinda hard with giant IC resvoir over the connector to test when car at 230, tank would have to come out WHILE it is overheating, gonna remove tank and test fan directly to battery, then crank car while cool, turn on ac and test at...

    Has anyone ever disconnected the 3 prong plug and somehow wired in one of those temp probe controllers to bypass entire system and have turn on with that probe that sticks on the radiator itself? I had a parts house one on my 79 F100 and it was perfect and easy. Figured if I knew how to wire...
