1994 5.0 GT Temp/Cooling Issue
Hello all and thanks in advance.
I just traded my bro-in-law for my 93 4runner. New to the mustang scene. Already I'm stoked for some modding. But 1st to fix the issues with the beast.
I'm having temp. issues: please read and reply with ANY ideas.
-Filled Rad & overflow to correct levels
-Start Car
-Idles 800-1000RPM, A/F mixture/ecu issue, I think, kinda glugs, throttle response poor, have 70mm TB & Cold Air, could be this?
-1 min. then idles fine, temp. @ cold start already low-mid (should be minimum on any other vehicle I've had) on guage.
-Let warm +/- 3 min. temp @ normal-mid-high, idles normal throttle response normal.
-Go for run up street & back 1mile total, temp guage reading just under redline.
-Get back and burp system. Rad Fluid spurts out, fluid is very cold, same temp as when I started the car.
-Temp on guage still redline so fan is on and working.
-Oil pressure just above mid.
Thinking that the sensor is working and it's either clogged or my water pump is gone.

RE: 1994 5.0 GT Temp/Cooling Issue
Dude, I had a very similar problem with the 5.0 in my 63 Falcon Rag-Top. Drove me nuts for a while. My problem was solved by installing a thermostat with flow holes that let a little fluid flow through even when it is closed. Got the tip from a local mechanic that has been drag racing small blocks for over 35 years. He suggested drilling a 3/16" hole, but Summit racing had ones already designed like that. I figured for all the more a new thermostat costs I'll just buy new.

Edelbrock Performer fast burn heads

Still have belt driven fan, electric in shop. Takes a little longer to get to temperture, but never goes above 200 even when running the **** out of it.
