I have an 06 dts with 182,000 miles..when I am sitting/idling the coolant temperature rises to 3/4 mark and the heat blows colder but as soon I accelerate it's the coolant temperature goes back to 1/2 and the heat blows normal.does anybody have any idea what's going on here.

Firts thing you got to do is to check the antifreeze it has to be low you may a leak some where. Add some antifreeze

I found the leak the water pump is leaking smh but I'll take that over head gaskets any day ..any write ups on replacing water pumps

 

[grullon10]

You have to remove the water pump housing I would recommend to do it asap . The pump may break and make sure they replace the haousing gaskets

I changed the water pump and thermostat earlier today was a PITA.. now no leak but the coolant in the tank is bubbling/steaming.

The thermostat is easy to put in backwards... "IF" it is backwards, it will not work properly.

I put the old thermostat back in the new one is a lil bit taller how do I burp the system

 

[grullon10]

It would do it by it self let it run with the cap off until the fan come on and sime of coolant come out

 

[basic_390]

Ok its running fine now (coolant wise) not bubbling or over heating .. now I'm having a problem with the idle while I had the water pump housing off I cleaned the throttle body and upper intake with carb cleaner and now it idles at 1600 rpm and accelerates by itself

It should go back to normal by it self or you may have to take it tobe reprogram.
