I would like that they could help me solve a problem that is causing my minivan Plymouth Grand Voyager 1996 3.3l, after a long route or rather when he already did all his process of lighting fans and maintain Ocaciona that bursts me hoses and even the radiator cover, already tried to change the water pump, the radiator for a new and rectified head of heads by putting new head packages, but the problem continues, adding more to the subject does not heat up during the march.

It may be that the head is crooked in a milecima of Milimeter
