I have a question, I need to replace my radiator on my Newell 1970 petrol engine ( 391 ) I can have a new frame put in with the old one, or I buy a new one which is probably better, but hard to find here in the Netherlands. Does anyone know what type of radiator or from which vehicle the radiators were used in the Newell's  in that time ? That would be a bit easier to search.

Thanks in advance.

Newell suggested checking the connections at the sensors. So, soon I'll have to crawl under and check.

Any ideas? What should I be looking for? How can you tell if there is a faulty sensor. Any input would be helpful.

I am taking the coach there next month for the annual service and they seem pretty confident that trying to repair the leak by welding will work.

Has anyone else had this issue with their coach

Have any of you had to fix or replace the DPF aftertreatment harness or sensors on a CAT C15??

My C15 has two codes for bank 1 DPF gas temperature. One each for input and output. Sometimes its "Voltage above normal" and sometimes its " Voltage below normal". I have it at a repair shop that has the CAT diagnostic software. That shop said the coach needs an aftertreatment jumper harness from the engine harness to temperature sensors, as well as a doc inlet clamp and gasket. Of course this info was obtained via CAN bus debugging, not taking anything apart (Shop is disassembling tomorrow). The shop called CAT to get parts, after which CAT said they don't make such a harness and we should call the coach maker. The shop emailed Newell who said they don't touch emission parts. I guess we'll see what we have when they disassemble tomorrow and look for part numbers, if any. I certainly hope the part numbers are on the bad parts, or the parts are obviously failed (such as a broken wire or connector, or sensor that measures out of range, when isolated.

In any event, has anyone had to repair this area or have a wiring diagram? Photos would be great but Santa didn't bring 'em and I can't wait for the Easter Bunny.]]> Here is a fun one.

If you have a VMSpc question please give me a call. I was Silverleaf’s only vertically integrated kit supplier. These were ready-to-use, plug-and-play kits. Everything was ready to use right out of the box.

Silverleaf cannot get chips for their data interface boxes (the JIB) so components are hard to come by. But I can help if you have functionality questions, screen designs and more.

Thanks to those guys who did a walk around our coach! If you don't have a tig then silver solder would work or hire it out. If your coolent recovery tank has no fluid in it your bound to overheat at some point.  Also you must leave the top cap loose so the recovery part will work, I cut a 1.5" hole and used a plumbing pipe stop to cover up the area where you would fill it but leave the cap on the fill loose. The diameter of the tank is 8" if you care to shop elsewhere but I used the same brackets that came with the plastic tank.
