<FONT face="Arial, Helvetica, sans-serif">Before I run to the dealership so they can analyze the problem for several days, has anyone with a '02 1500 w/4.7 experienced an loss of coolant? I did the usual checks, no leaks either cold or under pressure. No signs of it anywhere. I know what this typically means, but it doesn't add up, no loss of power, no missing, and no excess pressurization in the radiator. Answers anyone?????</FONT>

 

Hi Randy.



My '95 2500 V-10 used to always run at the "FILL" level on the
expansion tank. I'd fill it up to the "FULL" mark and a week
later it'd be at the "FILL" mark again. Only after I backed into
my parking spot on freshly fallen snow did I realize my answer.



The coolant overflow hose allows the coolant in the expansion tank to
splash out during abrupt manuevers. Since I had to make a
three-point turn (usually at speed) in my driveway, I was splashing out
the coolant.



Another, much uglier possibility is that you're burning coolant.
After it's warmed up, do you see any sweet smelling smoke coming out
the exhaust when you rev it?

Same thing here - If you figure out what gives, let me know. I'll lose 1 gallon every 6 months or so.

I was just reading through some of this old stuff. I was loosing some and the pressure cap needed to be replaced. Had a 03 QC wiff the 4.7l.

Got the 05 hemi now ]

 

i was searching around and found this. same deal loosing coolant out the overflow. i put a new cap on from the dealer and it didnt fix. i had a radiator pressure tester on it and didnt loose pressure. when its cold in the morning you can hear air bubbles sometimes in heater core. seems to me like headgaskets leaking but it runs fine,no smoke or anything. its going to the dealer asap. mines using a gallon a month easy

 

I say headgasket leak. My stang burn a little coolant and it doesn't loose any power, noise, nothing.
