Average mileage for rebuild on 2006 CXN613. ASET AC 350. truck has 550k miles and working fine I just want to have an idea so I can put the money aside thanks

Hi everyone, has anybody experienced this sort of coolant leak with this engine? Description: it leaks somewhere behind the engine, I can’t really tell where is coming from. And it also leaks from a fitting on the right side towards the back. Any feed back will be appropriated. Thanks AB

I stopped by the local Mack dealer today and I had a chance to talk the shop manager. He gave a similar explanation about those engines and transmissions wich it makes a lot of sense. I'll be running in Texas 99% of the time so big hills are not much of a concern. Another interesting point about this truck is that it does have two rear axles but only one differential. Should this be a concern? Thank you.

Thanks for the feedback, TCJ.

It is Maxitorque 7 speed. Thanks.

Thanks, AlexG.

Hello everyone. I'm new to the forum I have been reading through and I'm amazed how much information is been shared here. You guys are great. I have been trying to buy a Mack truck for a while but I didn't have the chance until now. I came across a 2007 Mack Vision conventional sleeper truck with an AC 350 (cxn613) engine setup that really caught my attention until I found out that it has a 7 speed (no splitter, straight 7) transmission. I have never seen this set up before on a road tractor. My concern is whether this truck will be able to pull 80k down the road and especially on hills. Is this engine and 7 speed transmission a good set up? Does it have enough horsepower to pull 80k without issues? Thanks in advance. Truck's info: 2007 Mack Vision Engine: AC350 Tranny: 7 Speed
