Didn't you just ask the same question yesterday?jamesmdx1 said:Hello everyone
where are the coolant drain plugs on the N* engine
and how are they accessed?
I want to change the coolant today
You can use DexCool with any other type of coolant, but you have to change it following the recommendations of the lowest common denominator. Green coolant contains silicates that plate the internals of the cooling system. The silicates will invalidate the extended protection properties of DexCool so, while it won't hurt anything to use it, you don't really get any benefits from it either. I would just use the green stuff and continue to change it every 2 years.jamesmdx1 said:Thanks Michael
Yes I did ask a similar question yesterday
I was reading in the service manual about draining the left and right engine block plugs, but they did not say where they were.. I really didn't want to bother with them anyway..
I know you said to use the green stuff for a '94, any reason?
Can I use the orange one (DEX COOL)
thanks for the response
It´s not my intention to be a smart-ass but there is drain plugs. At least on my -93 STS.mcowden said:Didn't you just ask the same question yesterday?
There are no block drain plugs on a Northstar 4.6L V-8.
Thanks Chevelle for the great explanation. Ranger, I should have said low rpms, I´m not THAT stupid you know...Ranger said:How does slow driving cause a burnt valve? If that where the case, every city driven car would be burning valves.
No offence taken! You´re right about that being unlikely. What worries me most is the fact that the car had 100000 miles on the counter when I bought it and several previous owners too. Couldn´t resist the price though...9000$ for a car like that here in Sweden -03 it was cheap :crybaby: For all I know they could have been using any kind of oil in it, not to mention what they could have done to the cooling system.Ranger said:Never meant to imply that you are stupid. Hope you didn't take it that way. I think what Chevelle is saying is that anything is possible, but I still think it is very unlikely. Many many cars driven aroung by "blue hairs" that never see high RPM and you just don't hear of a rash of burnt valves. If the type of driving you discribed burnt a valve, I would expect there to be an epidemic of burnt valves at most city dealerships, no?
