Mentally Unstable..
OK, here goes. Moderators, please move with if you feel it should be moved. I am not looking for specifics, just general input and I figgured it would get more hits here.
I want to keep this civil, becuse I MAY have to use quotes off this in an interview with head office of IH. If you guys have differences of opinion, PLEASE do not hash it out here. I can understand differences of opinion, and we should have debate here, but please do it respectfully.
Please, when you post, state if you mind me quoting your reply (no names will be mentioned, even if you give me permission I am not using a name), ANY mechanical expirence and backround and why you think coolant being burned is an issue in a direct injection diesel engine.
The issue is this....
My buddy has a '10 IH Maxxforce 350 HP engine in his Workstar. It is losing coolant out the butt...since 6200 miles, he has been fighting with them with NO results from them. They told him it was a cold leak, but wouldn't compression check the coolant system until I made the owner DEMAND they do it at THEIR cost.
The truck now has a hair under 50 000 MILES on it, and has drank something like 6 or 8 gallons of coolant....most of it being consumed over the past 3 - 5 months.
IH knows about it, and has been telling him to keep an eye on his coolant loss. (BRAND NEW TRUCK, WHY IS IT LOSING COOLANT?!) They claim that so long as no white smoke is blowing from the stack, that up to a gallon per week is "normal" consumption and won't hurt anything. There about 15 trucks around here that are all acting the same way. So it's not my buddy or his driving technique.
I know my opinion on this. ANY liquid besides fuel that is introduced into the cumbustion chamber on an engine that has a 17.5:1 compression ratio is just asking for problems.
Anyone who does not know, the DT/HT 570's Maxxforce 9's and 10's (for sure, possibly other IH engines as well) are losing coolant through burst EGR coolers. This lets the engine drink it's own coolant.
EVERY truck I have seen with these mentioned engine are in for a COMPLETE rebuild before 60K MILES...
I have done a PILE of research and found that the coolant is to blame. The silicate drops out, plugs off the TINY passages in the EGR and oil coolers and causes all sorts of problems.
Anyone know of ANYONE else with similar issues and getting the run around from IH?
