I’m thinking my thermostat may be sticking. I’m looking to change it out. I have the 6.3544 model NA with the manicooler. Is there just one thermostat or two?
The book says it’s just one and it’s under the thermostat housing neck on top that’s headed towards manicooler and when changing out make sure to intstall one that is a bypass thermostat.
When I go to order thermostat, the Perkins people (Diesel Parts Direct) says that it takes two. Has anyone changed one out with the MANICOOLER and not the multicooler? The book says the multicooler takes two and they’re in a different housing that is below this neck. Here is a picture of the neck on mine.
