I flushed my dirty *** cooling system and put in a 180* thermostat. Mistake. These are looking for 195 or they are in open loop mode- like the choke is on.
Even had black smoke out the exhaust. -
No code. - had to monitor w tool while running to figure it out.
I put a 195 in the 02 Ram 5.9 I had.. Napa Perscribed. Went back to a 180. Just to hot for mid south Fla. Didn't notice any adverse affects, just the temp a Lil lower!
