So the intake manifold on my 98gt went out and started leaking coolant so i bought one from a junkyard, i got it out of a crown vic and used the coolant sensors from the crown vic, now my temp gauge on the dash gets really hot like almost onto the H but i dont think it has actually left the normal range, the point is before i put this intake on my car never had overheating issues and the temp gauge usually stayed at halfway or slightlyy below, what am i doing wrong???
