spacecoastshelby Posted November 11, 2010 Report Share Posted November 11, 2010 Anyone have an idea of what would cause a motor and attached components to be very hot after driving without getting an overheat indication from the temp guage? I noticed that the motor, intake, throttle body etc. were all very hot after driving...even up to an hour after sitting in the garage, they were hot to the touch. Trying to figure out what was going on, it appeared the collant resivoir was filled with the dexcool (orange coolant apparantly put in by the dealership I got it from)...so I immediately took it in for a full flush and had the proper coolant put in. Now she is cool to the touch even immediately after I park in the garage...could the coolant make the engine block that hot without the fluid passing through the thermostat getting hot enough to register as such?

TheKurgan Posted November 11, 2010 Report Share Posted November 11, 2010 Not using the correct coolant could cause problems such as overheating, absolutely. Link to comment Share on other sites More sharing options...
stormeaston Posted November 11, 2010 Report Share Posted November 11, 2010 This is off the top of my head but I don't think we're suppose to use the orange stuff (Dexcool) in our cars. Link to comment Share on other sites More sharing options...
spacecoastshelby Posted November 11, 2010 Author Report Share Posted November 11, 2010 This is off the top of my head but I don't think we're suppose to use the orange stuff (Dexcool) in our cars. I think while I was searching for the answer I noticed that the coolant resivior mentioned not to use the orange (dexcool) and that is why I changed it out right away, but I thought it was strange that the heat could get so high to radiate that heat to other components without registering "hot" on the temp guage. But it is all good now...but I agree the dexcool is very bad for our cars! Link to comment Share on other sites More sharing options...
springer Posted November 12, 2010 Report Share Posted November 12, 2010 What is this "orange stuff" Dexcool? Is it a Ford product? Antifreeze? Why is it so bad for the cars? Thanks. Link to comment Share on other sites More sharing options...
ARMORINE Posted November 12, 2010 Report Share Posted November 12, 2010 What is this "orange stuff" Dexcool? Is it a Ford product? Antifreeze? Why is it so bad for the cars? Thanks. its an extended life coolant that alot of cars are coming with, suppose to last five years or 150k miles or some bs like that. im not sure what makes it bad but apparently its not modular motor friendly Link to comment Share on other sites More sharing options...
springer Posted November 12, 2010 Report Share Posted November 12, 2010 I just did a google search on Dexcool. It looks like this is some pretty bad stuff - it turns to a muddy substance after a few years. Check out these photos, this stuff is unbelievable. Hopefully Ford isn't using it from the factory.

This is another reason why I stick to the manufacturers recommendations! Link to comment Share on other sites More sharing options...
springer Posted November 12, 2010 Report Share Posted November 12, 2010 It looks like Dexcool has been used exclusively by GM. I could not find any data that Ford was using Dexcool in their cooling systems. Link to comment Share on other sites More sharing options...
motorjock205 Posted November 12, 2010 Report Share Posted November 12, 2010 Most of the 2005-2009 Mustangs used the Motorcraft Premium Gold Engine Cooland VC-7-A NOT the Dexcool....Dexcool is a GM product NOT a Ford product...So don't panic if you see something that looks Gold or Yellow in your Mustang!

stormeaston Posted November 12, 2010 Report Share Posted November 12, 2010 Dexcool is used in GM cars only, my kid had a Grand Am one time that had a leaky head gasket and this was the stuff we had to use. Link to comment Share on other sites More sharing options...
kahmann Posted November 12, 2010 Report Share Posted November 12, 2010 Dexcool is no bueno in a mod motor for sure. I run straight water with a bottle of Water Wetter for good measure and have zero issues. The C&R radiator is an awesome mod, by the way. I highly recommend it for anyone and everyone with the 4.6.
