Snowy Posted June 9, 2009 Share Posted June 9, 2009 The Manta haynes manual states that for the 16S, 19S and 19E the operating pressure of the cooling system is 13.2 - 15.2 psi. But in the 78 - 86 Carlton Haynes manual, using the 20S engine, it states that the pressure cap opens at 102 - 115 kPa (14.5 -16.3 lbf/in2). I should imagin that there isn't much difference between the 1.9 and 2.0 cooling systems. But in the past i have bought 13psi pressure caps for a GTE and had no problem with it leaking. I hope this helps a little. Quote Link to comment Share on other sites More sharing options...
