Heatsoak?

Guys, I've got an e99 F350 that I recently put gauges in, and am noticing my trans temps creeping up while doing my in-town driving (which is 90% of how I use the truck), as well as my A/C wanting to fluctuate temp-wise when the truck is just driving around. I'm seeing trans temps at 190-200 in stop and go traffic, and have seen 210 before changing the fan clutch today.

Changed the Clutch, as it was a bit loose/weak. I rarely ever heard it kick on, but have noticed the new one doing it more often, so I'm sure its helping, but it didnt fix the problem. I actually noticed that the A/C kicked completely off today while I was idling at the shop.

I'm actually quite confused. The trans fluid was red when I got the truck, and I'm about to head out and check it again. I really don't need to be without my truck, as I work out of it.

Plans are:

-Blow out the stock dinky cooler, and see what comes out.
-Check and make sure fluid isnt changing colors on me.
-start saving for a 6.0 cooler, Sonnax, filter, and a bucket of mercon
-Put gauges on my A/C and see what my pressures look like.

Any other suggestions you guys would give me to get me by for now? I've seen the graphs aout engine life at temps, and understand the damage that these temps can cause. What would you guys do, in the essence of keeping the truck on the road as much as possible?

Re: Heatsoak?

Anyone have experience with the Flex-a- lite fans?

I'm sorry, but I don't see a problem. What are you trying to fix? Your temperatures are completely normal.

Re: Heatsoak?

As far as the a/c check your clutch and reshim as needed. Trans temp, figure about 100 deg over what it is outside, give or take.

What are the normal temps Mark?? I may be the cause of all of his confusion. I could have sworn that 180-190 were where it should be unless you're pulling... What is the maximum acceptable temp?

Re: Heatsoak?

Maximum sustained temperature is 220F. Maximum short term, for no more than 1/2 hour, is 250F. Running 200F in stop and go driving is normal.

Re: Heatsoak?

Thanks for the help... Just hate that I freaked out as I did. The fan got a new clutch, so It couldnt have hurt. I do notice the new one kicking on more often than before.

Mark, I wish I had known you, or posted a thread before I did. It probably would have saved me some heartache and fundage. That fan clutch was an expensive booger! I'll probably keep my original one, just in case.

irontx25, are you talking about the A/C Compressor clutch, or the fan? Could you elaborate a bit for me?

Re: Heatsoak?

Fan clutches do wear out. It's likely that your 11 year old clutch was worn out and needed to be replaced.

A/C clutch. Its like any other clutch.....it wears. Mine would blow hot on full a/c. bought a new clutch and when i pulled the old one off i noticed it had shim washers on the hole the bolt goes through. I pulled 1 washer out ,slapped it back together.....cold a/c like it use to be.
