went to goldbridge and had a hell of trip because of the fukin dodge

here's the deal

2002 dodge dakota 4.7


truck is over heating bad
oil is clean
coolant is clean
no leaks any where


changed the thermostat because of overheating issue 2 weeks ago and had no problems before i left for goldbridge but once i got to hope things got hot and was overheating for the next 300 k stopping constantly for cool down

i bought a new thermostat in lilooette and made it goldbridge barely

wile camping i decided to pull and hollow out the thermostat re filled with coolant and seamed to be fine all though was over cooling.

left for home and had the same problem all the way but this time with no thermostat

here's some weird symptoms
stays cold at highway speeds sorta
cools when on the throttle heats up when coasting even down hill
only have cabin heat when on the gas
over flow bottle full and cold the whole way

wtf :dontknow:

Impeller on the water pump not spinning except under load?:dontknow:
Does sound like a flow issue,any coolant movement with the cap off when you were refilling?

thats the same prob as my 360 Eric!

and I do have flow ,and taken the water pump off to check the impeller and it is fine?

check clutch fan, if not fill coolant with upper rad hose disconnected and heater hose disconnected and allow overflow.

For sure, you have an airlock.. do what he said, and if it's still doing it..

plugged rad.

after letting it warm up. shut truck off and feel the fins all over and both sides of the rad checking for cold spots. If you find any cold spots the rad is plugged.

since that is easy and free i would do that first.

sounds like air lock to me check for bleeder screw on metal hose

Would be allot easier and cheaper trying the airlock fix first to see if it helps and then do the pump if needed...good luck with it.

sounds like a blockage in the system, the coolant shouldnt come out when you rev it with no thermostat.

burp the engine first.. if tht doesnt work, go get a flow test done on the rad.

Because the problems are consistant with the speed Iwould be looking for
a water pump.Even though you see movement in the rad when it's
running the impeler could still be slipping or NFG ?

A bubble can cause that too - restricts water flow.. a blocked rad can cause that as well - faster airflow provides more cooling capacity.

the fact that he JUST changed his thermostat makes me think bubble as he must have lost and refilled some/all coolant when he did that....however he changed it FOR a cooling issue so i'd start to think about a plugged rad.

:confused0006: seems to be fixed now :dontknow:




drained old coolant reinstalled new thermostat then filled both rad and over flow and ran 45min with no cap on the ramps to give the front end some elevation then put shiny brand new rad cap on and let run for 15 min more
then let cool for a couple hours went out and managed to get 1/2 liter more in

and now she seems to be good :dontknow:

meh !! [16] new fucken trucks


thanks for all your input [cheers]

not new trucks eric, my pathfinder is the same way.. I have to bring it up to temp with the cap off the rad, then fill it as it goes down.. if i don't it gets a bubble in the engine and overheats.

Good to know it's fixed with no big $$$ spent:)

i think it was the shiny brand new rad cap that fixed it
