engine temp and towing??

[sag2]

I have a Granatelli monitor, and it shows actual numbers which correspond to a mechanical gauge I installed at one point. While it shows a trend, the in-dash gauge is not accurate by any stretch of the imagination.

I have spent many hours with factory scan tools on all CJD products and while the oil pressure is not real, I have found the temperature gauge to be very accurate compared to the temp sending unit being read by the PCM. Sometimes the cluster will "soften" the movement of the needle, but the temps reflected tend to very close to the actual. Generally any error will be the same throughout the range of the gauge.

Yes oil psi is fake, I don't even know why they put a gauge in, when there isn't a pressure sender on the block.



Coolant seems to read a little high on the dash vs the OBDII port on my truck, maybe 2-3*. Other wise it moves very close to the OBDII.



Voltage isn't all that accurate either.

I have noticed on mine that the fan clutch don't even kick in until the gauge on the edge hits 215-217, just running down the road 65-70 mph with a/c on, 100 degree day pulling our 16k 5er mine will run between 215-220, egt's 800-900.

So do you recommend putting in "real" oil and temp gauges? If so where? Should I tee into the factory oil sender or go off the oil cooler housing? For coolant temp I assume using one of the plugs in the top of the head at the rear would be the best. I wasn't going to put them in this truck. (On my last rruck I added 7 gauges. ) Thought I would go with the Dodge ones to save some cash. I have pyro, boost and fuel pressure already. Shadrach

In my experience, they tend to minimize/dampen the movement near the "desired" range... the temp needed to move it from cold to "normal" is not on the same range as that required to move the needle around the normal scale. And it was significantly less (in both readout and movement) than what I read with a real temp gauge in the head.

I had my oil pressure (and oil temp at one point) in the oil filter head... placed my coolant temp in a plug in the head on the passenger side.



And don't get me wrong, while the temp gauge is a "real" reading; they are only showing the "trend", and not a real accurate number. In other words, you could be running a lot hotter than the gauge reads (by almost 20*F in my case) because of the dampening.

The oil pressure gauge is never a bad idea, the psi switch is 6psi and that's too low at any rpm.



While coolant temp on mine appears to be a few* off its pretty good, nothing I would worry about. When I saw 220* towing it looked like 215-220 on the gauge. The coolant will also run a few * hotter than the thermostat based on the location of the temp sensor and the thermostat.

mine runs 200-210 bob tail but i have a Top Gun bumper and i wonder if thats what makes it run hotter than it use to. I'm considering taking my bumper off and putting the stock one back on. when it idle for a short period it cools down to 180-190 on my gauge in the cluster

In the shop here where I sell the Amsoil products, we just had a truck come in(12 Valve) that had become so hot, the bolt holding the "Block Heater" in the block broke and the pressure inside the block forced the block heater out of the block! This has never been seen here before. The head gasket was also broken due to the high pressure that developed from the overheat problem.



The BOTTOM LINE... ... ... ... ... ... ..... Watch the COOLENT TEMP!

 

[rbattelle]

We have some John Deere tractors that we run just into the red (235) all day long, for years and it never hurts them. I would not worry about 210

That's good to know. We should bear in mind this engine is all iron, and will handle higher temperatures quite nicely. Higher jacket temperatures are good for combustion too.



I've noticed the heat flowing from the A/C system into the radiator on hot days will increase coolant temperature up to 5°F, depending on grade.



I continuously monitor my coolant temp from the OBD-II reading, and find the in-dash gauge is pretty accurate - as "accurate" as one might expect from a gauge with only 3 values on it. Not to mention the weird calibration - the first half spans 60° and the second half spans 45°.

I ordered an Isspro triple pillar pod and oil pressure and coolant temp gauges. They arrived today. I now have 6 Gauges: pyro, boost, fuel pressure and air pressure as well. What can I say I like to know what is going on in the engine. Shadrach

Downshift one gear and it will cool down.

One more reason to buy a stick. Shadrach

Shadrach--Cumminz --I couldn't agree more. I have the NV-5600 and just returned from a trip to the mountains in New Mexico. Almost amazing how the EGT and engine coolant temp will decline with a downshift. Really like the flexibility of the six speed.
