19# is stock. I know someone will correct me if I'm wrong.Rick Anderson said:Plus 19 PSI sounds a little high, do NOT all the system use the very common 16 PSI?
Ecomike said:Haynes says 1984 -2000 year has:
4 Cyl & V6: 12 to 15 PSI
4.0 L, Str.6: 16 to 18 PSI
And there is a debate thread going on this past week as to what the renix era plastic bottle plastic cap vent pressure is rated for!
They may have changed over the years, especially 1990 to 91, 95-96 and 2000.

A look under the hood confirms that I was wrong. It's a 16# cap not 19#. Sorry for the confusion.jelrod said:I'll pop the hood as soon as I get home and post up what # is on there. It's been on there since I bought it 2 1/2 years ago. Who knows if or when it has been replaced.
Ecomike said:What a novel idea :eyes:! Testing them!!!!!:laugh: 5-90 gets the award on this one!
Way to go 5-90!
I think we can put this question to rest now.
