Do I read correctly that it is the injector cups that dictate the coolant I have to run? Not knowing how long the "non green" coolant has been in there, are there any symptoms I need to be on the look out for? Or at least aware of?
Don't know the PO. I plan on flushing, but I wasn't sure if I need to be watching for anything in particular. I currently have a click or knock that can be heard clearly during deceleration. It sounds like the video Tugly posted regarding an bad injector when at idle. http://www.ford-trucks.com/forums/12...hing-else.html However, I have been searching for why it make a click during the deceleration (injectors off). While searching for an answer, I came across the coolant "issue". I still can't figure out the click/knock noise.
I have an E99 that I have acquired. It currently has coolant that is not green. Based on what I have seen in other posts, Is this a problem? Should I be alarmed?
What color coolant is in the truck currently? Some pre-charged conventional coolants, basically "green" coolant with SCA's already in it, are different colors... purple, blue etc. Which your E99 would be fine with.
As far as ELC in an early 99 IIRC it is the sealant used on the injector cups isn't ELC friendly. Suffers the same fate as the as the sealants used on 90s GM engines when they first introduced Dex-Cool. Dex-Cool is a OAT based coolant, like ELCs, that uses 2-EHA (that many ELCs do as well) which will eat some sealants and gaskets.
