It can expose a myriad of sins. 15 psi is called for. I would check it cold AND after it has reached operating temperature. I have seen hydronic systems test out good cold then, once up to operating temperature, it is time to get out the umbrellas. Although, Vanagons sometimes seem to show their weaknesses more after they cool down. Rich |
