OK guys,
I've been running hot on grades at highway speeds and slow going on uphill treks on dirt or crawling. Here's what I've done.
1990 4.0 RENIX with open cooling conversion. Been fine for the last 2 years. HD trans cooler directly plumbed, trans/cooler/trans, not thru the radiator.
Everything works fine except this one issue. So, any ideas?? I have it apart right now and I need it on the road tomorrow. I could just button it up with the older parts but since I'm already half way ther I'd like some input on which way to go.
Thanks

- New fan clutch (has resistance when I spin it when it's hot) 3 months old and less than 1,000 miles).
- New 195* fail-safe t-stat. Well, 2 months old, tested it on the stove before I installed it.
- Triple flushed entire system (block, rad, heater core) - twice.
- New 16# cap (ported).
- New 50/50 mix coolant.
- Heater Control valve is operational and not clogged. Been thinking of deleting it altogether.
- Coolant looks brite green and clear (but there is a bit of crud on the inside of the cap, not oily stuff, just cruddy). Oil fill cap looks good. No crap or film in overflow.
