|rman||Thanks again guys, I'm pretty sure it's completely fixed. Ran her to 95mph up about 1/2 mile at maybe 4-5% grade, hit 13* delta max and dropped to around 8 once I let off.|

|powerstrokeshellback||When using the cleaners its not unexpected fro some crap to get loose and clog the new cooler. If your 10 degrees or under at 70 unloaded I wouldn't sweat it. If you got a warranty I would have them put in a new cooler|

got my 7.3 fan clutch installed.
i don't get it. at all. But everything so far seems fine.
It's hard to do the test in San Diego, lots of hills and everyone drives 75mph.
So I just romped on it, 75-80, moderate engine load, etc.
Averaged 6-9* delta
Max was 13* and that's running 80mph and immediate decel dropping my ECT.
Before oil cooler deltas were 18-20*... so I2sure it was plugging, but probably not as bad as I thought. ECTs did climb though.

thanks guys. i get a little... obsessive with a dash of denial and hope haha.
plan to do the BPD 7.3 conversion. Looks like they use the Sever Duty Hayden... 108 on amazon. Anyone know of a better fan or deal?

despite your normal ECT what we are trying to say is u can't use your delta's as a comparison against a database compiled of trucks that had a properly working fan clutch's
so it's not worth discussing until you get it fixed
either with he BPD conversion , a OEM snowplow or stock clutch

|rman||brand new OEM tstat, new water pump. ECT is dang near perfect|

|HeavyAssault||I'd say get a tstat for replacement unless that was done with all the other work.|

Stock or 7.3 doesn't matter, you need to fix that issue...
You will run all kinds of strange numbers until that fan is doing its job. It isn't just a matter of pulling air, that fan keeps a consistent air flow through the radiator. The spaces between the condenser, intercooler, and rad create dead spaces where air doesn't flow well. Much like behind the cab on your truck there is a low pressure zone, you get that in between all of those layers as well. As things heat up and need more air flow that fan kicks on (right around 220*) and forces air through.
You will never get consistent deltas without the fan clutch working properly. But... Anything less than 10-15* is acceptable.

also, i read in another thread awhile ago that someone showed a pretty big variance with their SCT or Edge vs. AI or similar.... which if that were the case... my deltas were never really that bad haha.
Would hate to have all this $$ in my stupid livewire and end up having to add a couple gauges to monitor deltas more accurately.
