cooling water temperature

[gajol]

Hello,

i have exchanged the voltmeter for a temperature gauge. while driving the temperature sometimes went up to 230° F. What is the maximum temperature for the engine? Is that normal?

Thanks for your advice.

https://www.steelsoldiers.com/threads/6-2-diesel-correct-operating-temp.106003/ You are at the maximum range. I would look into getting the radiator and thermostat cleaned and changed out. Good Luck.

thx for your hint. i will have a look for the thermostat. the radiator is new.

Upper hose where it meets the engine. That 2 bolt flanged housing is the thermostat housing. Use care when extracting the 2 - 15 mm hex bolts. Sometimes the aluminum threads come out with the bolts. Good Luck and Please report back.

Fortunately, the expansion worked out well. I ordered the thermostat directly from rockauto.com in the USA. I ordered on Saturday and the parts were with me in Germany today. That was really fast. The Aluminuim part is a bit warped and wants to do the sealing with Hylomar M. I am still waiting for that now.

Good Deal. Looks like you are on the right path. Be Safe. Good Luck. Thank you for reporting back.

here is a short update: i installed the thermostat and only sealed it with hylomar, that did not work. There was a big sourness. i have now sealed with two layers of paper seal and hylomar. it seems to work now.

1. Where is the gasket? I would use a gasket in conjunction with gasket sealant.
2. Is your temperature gauge electric or manual? I just had some interesting problems with electric thermostats giving me false temperature readings of 220-240 degrees while the engine was actually running 195. I ended up replacing the gauge with a mechanical and all is well. https://www.steelsoldiers.com/threads/running-hot-or-maybe-not.193753/
Good luck.

i tried the sealant at first and it didn't work. with paper sealant and gasket sealant it looks good so far.

that's what i was afraid of, but didn't know what it could be. thanks for the link, it helped me a lot.

I would highly suggest adding in a Cooling Upgrade Kit from Paradox to ANY 6.2/6.5. Make a huge difference in keeping the temps balanced across the block and heads as well as burping the back of the block constantly.

I bought and recently installed one on my M1010. Haven't gotten the new gauges in so not sure what temp I am running but figured it would be good to keep temps balanced.

It's not a bad idea to verify temps with an IR gun.

I have a mechanical coolant temperature gauge, a failing thermostat will go to 230 °F . You will feel a lot of heat from the heater core too since these don't have heater core bypass, there is always coolant flowing through the core.
I had a 4 month old Gates OE style fail on me. Now running a generic one made in Israel. 14 months no issues.
