Meter

Does a guy need a meter to check his exhaust temperature.And turbo boost. I notice my heat goes from 180 to 215 when I get on steep grade. Isx 600

Agree.

At around 205, you need to be looking at "Plan B" to keep the coolant temperature from continuing to rise.

Basically, find a gear where you are close to the high end of the engine's RPM range. Throttle position short of WOT. Said another way, if you floor it, you can still accelerate.

If pull out available, put transmission in neutral and engine RPM around 1,200. Unless you have a coolant leak causing the overheating, engine temperature will quickly return to thermostatic control.

If not able to pull over, before chancing an engine failure/derate, turn on dash heater to full hot and fan to high. Think of this as an auxiliary radiator. Better for you to be hot for a few minutes, than be stuck at the side of the road and with a significantly lightened wallet.

215 is higher than I would want to see. I've climbed most passes out west and 205ish is as high as I've seen. But I'm heavy & underpowered so I downshift early & often. I have been in 3rd gear reaching the summit of some of the bad ones.

If your engine is OE, not "modified", you do not need a EGT gauge. Cummins took care of insuring that it could not over-temp.

Absolutely if you have modified it, adding more fuel, you need one.

Hit the down arrow on the Alison shift pad a couple times.

Ivylog told you what to do. Instead you want to put a thermostat in it different from what Cummins provided or alter the fan setup different than what Spartan specified. I dont get it.

In my experience, unless you are running a "tune" your engine computer should automatically de-fuel when ET"s get excessively high. Boost and EG functions are commonly over-ridden with performance tunes, hence the need for gauges.

No it doesn’t have a boost gauge. My Monaco did This is on Spartan. I deleted It an notice heat moves a little more don’t think in danger zone I hope not. I’m wondering about putting a 180 thermostat in

Sounds like you are letting the Alison do the driving…put it in D and push the right pedal. A Alison 4000 will lug a 600 ISX… will not down shift until below 1400 rpms which is fine in hilly terrain BUT not when climbing a mountain. You need to manually downshift and keep the rpms above 1800 when climbing for more than 2 minutes. Doing this should keep the temp below 200 and the exhaust temp well below 1200…if you’ll downshift you do not need an exhaust temp gauge. I’m surprised you do not have a boost pressure gauge on the dash.

IT would not hurt but... The question is how much it would help.
Now a processional highly trained Operator (Not just a driver) Might (or not) know the meaning of the readings... My brother was both a Semi Owner/operator and a diesel/gasoline mechanic I'm not that good with Diesels. He likely would know what an out of range reading meant. and what the normal range is. I don't.

So the meters MIGHT be of benefit to him. NOt to me without further research and study.

Since I do not know what you know in this regard The best I can do is guess. And my guess is your knowledge of the meter readings is closer to mine than my professional operator brotehr's.

Probably not too abnormal. Keep the RPMs up very high when you’re going up a steep hill also if your radiators a bit dirty it can cause an increase in temperature. If the engine coolant hasn’t been changed in the last 3 to 5 years that can aggravate the situation.Mine is done the same thing on steep hills. The important thing is to keep the engine RPM up high very high to keep the water circulating good.
