bought my first cummins six months ago and am hooked. but it seems my hydrometer was screwed up and my anti freeze froze up solid. thawed the truck not leaks except for a hose of two. truck runs fine but runs a little warmer than it used too. temp used to be a sixth the way up the guage under all empty driving conditions but now runs a third the way up but cools when i stop. it ocasionally fluctuates while i am driving too but it seems to be back and forth between a sixth and third way up. my truck has 250000 and want it to do another 250 but need to figure this out. did the waterpump and flushed the rad, only thing i can think of is the thermostat. two questions is a third way up the guage running hot? cause like this when i tow it will probably go to half if not more. and if its the thermostat were can i get one? do the cummins ones really keep it from fluctuating as much?

 

what does this have to do with thinking about buying a truck?

 

nothing. when i signed up it said if you are thinking of buying a truck or have a new truck and have questions click here. so if itsin the wrong spot can someone move it so i can get the answer to getting my truck up and going again

 

These gauges like to move around, mine did. Yes you must get a Cummins T-stat, the auto parts store junk most likely will not be sufficient. It wouldn't cool my 1st gen. My buddie just ordered a Cummins T-stat off Ebay, and when it came, it was NOT a Cummins T-stat. It was a junky knock off. When you get one, make sure it's from a reputable person, not off ebay. Just my .02 That's not the first person that has told me about knock offs packaged Cummins OE. WTF Not right

 

wow. thats b.s. yea i ffreaked out when the truck froze i was sure i cracked my block but i didnt. nowo i just need to get it cooled and steady asap cause i need this truck fixed like last week

does cummins mail parts. or is there anyone like genos that seels the real cummins stuff

 

Yes they do. There are sponsors here that will surely get ya the right parts. Make sure you put your burp hole at the top on the T-stat or you'll be taking it back apart like I did Seems silly, but I had to jack the front end of my truck up real high in the air, while running to get all the air out of my system, it was the only thing that worked for me. Good luck

 

well cant send u a message bill cause i am too new on the site but will definetly contact them to see how fast the parts will get here. any signs on how to tell real from fake?

 

Call Tony @ Mighty Diesel 877-354-7008 He'll hook ya upCummins T-stat just looks HD, unlike the cheap pop metal ones from the part store.

 

My NAPA thermostat works fine

 

got a cummins t stat and it didnt help. oh s*&t now what
