Question about 4320 engine temp

ArkLaTexSam · Jul 17, 2006

I went and drove a new 4320 cab tractor today (minus the FEL) and noticed that the engine temp was a little past the middle towards the redmark.

My 4300 never gets more than a quarter of the way from the cold mark unless I'm bushhoging in very hot conditions and the screens start getting clogged up. Even then, it has only reached the halfway mark a couple of times.

Can any of you 4320 cab owners/operators advise me if it is normal for the 4320's to run a little on the warm side???

My test drive consisted of idling for short periods of time and running the tractor in the low and medium ranges for about 30 minutes with the cab air on. The only 2 things holding me back on purchasing this tractor is the A/C temp and the engine temp issue.

My concern is that the engine will heat up even more when I start working with a bushhog causing the temp to rise too close to the redmark for my comfort. My dealer only has one 4320 and I've even thought about going to another dealer and testing an identical tractor to see the difference.

Thanks for any comments or suggestions,

I don't think you have anything to worry about as far as the running temperature goes. I have a 4520 and always warms up to just over halfway up the gauge, then stays there. I have run the engine at PTO speeds for hours at a time in 85 degrees and no breeze, using a big branch chipper. The engine temp didn't notch up at all.

And, it gets to the same point on the indicator in the middle of winter, too. So looks to me like that's the design temp for those engines.

Tom that sure makes me feel better. The temp outside was 101 degrees when I drove the 4320 today. The index was 107. DANG HOT!!! The difference in the gauge's caught my eye and I was a little concerned.

My 4320 tends to run in the 50-60% temperature range; less when the engine is below 1500 rpm. I figure it is normal.

My 4320 runs just a little beyond halfway (55%). It never seems to vary from there, regardless of how hard it is working.

I went to another town and ran another 4320. It seems they all run about 55-60% on the gauge which must be normal for these tractors. Thanks for all of your info.
