5.3L Runs Hot.....Anyone Else??

[Wxman]

I have an '03 TB EXT with the V8. The engine runs hot when outside temps are high (low 90's+). It doesn't overheat, just runs hot, sometimes over 235. This is not loaded, climbing mountains or towing. It is usually during city driving, but not necessarily heavy traffic. Has been in for service multiple times. Has had three new clutch fans, PCM update, reprogram and then total replace, new thermostat, flush and fill, and maybe more. Local dealer is out of ideas and apparently HQ has not been of any help.

 

Curious as to experiences of any other V8 drivers. Warranty is out in approx 500 miles.

 

Thanks

NO.

 

Have the belts and fan checked, I had them replaced under warranty. Now the truck runs alot cooler

Our's is an '05 5.3L, no overheating as of yet. I'll be keeping an eye on it since reading this post.
