Fan clutch engagement parameters
hayes was the one he mentioned...
mike, fan clutch test in the manual states it can take ip to 15 minute sor the fan to engage, seems like a design defect if it actually took that long but worth mentioning...
Was it Hayes or maybe a Hayden like this one (Hayden 3282)? https://www.haydenauto.com/en/ecatalog?year=2005
There's some speculation that Hayden might even make the OEM version.
I recall reading about the long wait time for the clutch to engage and had the same feeling. Seems like a poor design to let things keep heating up. I let it run for about 5-10 minutes at full operating temp, at idle, with AC on full blast. No engagement or fan roar. The ECM temperature thresholds to trigger fan engagement seem a bit high. Work stuff and an insurance claim has kept me from from further diagnostics today. We had a big storm here a few days ago that dropped a pretty big Ponderosa Pine on the house. Got it removed and now working on the estimate to get the roof repaired.
