Customer Question
I got a mbe 4000...
I got a mbe 4000 quickly heats up under a load. Accerlating heats up fast to over 200 Fan is not coming on when temp gets to 210 but works manually. On a flat on cruise it will heat up slowly and keep on heating up but I use manual fan at 200

Good evening, a couple things we need to check, one we need to make sure the thermostats are opening . This can be done by checking the temp with a heat gun. Check lower radiator hose it should be warm then around 185 the thermostats should open heating up the Lower hose
