Cat C 15 operating at low temparature

Thermostats

 

Ya the service life of thermostats is 2 years... Could be sending unit of gauge tho....

 

Most cat parts people know when we say thermostats they need to look for regulators. MHC at Little Rock hired a new guy, still have to tell him regulators.

 

T-stats.......if they don't fix the issue, you could possibly have a temp sensor bad as well. If the tstats don't do it, take it and have the temp read off the ECM and see what it shows compared to the gauge. Are you getting heat on the defrost? If not....def tstats. If your getting heat and gauge shows 150, check ecm temp compared to gauge......may be bad gauge

 

I've heard you should not use tap water to mix with your antifreeze. It has to do with the minerals in the water. I always buy be premixed myself.

 

thermostats i would say

 

You are right. But it is cheaper to buy normal concentrate antifreeze then get distilled water from walmarts or rite aid pharmacy for $1.50 a gallon.

 

When u filled er up did u go slow so all the air could escape? How was temps before u changed coolant?

if temps were fine before u may have an air pocket from fillin too fast
