Been toping off coolant every 3 days for a week now. Couldnt pinpoint the exact location but it maybe the pump is on its way out. Im planning on getting it replaced some time this weekend, since it’s our only vehicle and need to drive it tomorrow for work. I plan on replacing the pump, thermostat and belts. Are there any special tools I need for this? How long should I expect this to take? Do I need to use sealant before i place the gaskets? How much coolant should I buy to refill once Job is completed? And are the torque specs 22lbs for the pump and 11 for the thermostat housing?? ( those are the Numbers that kept coming up on youtube). Thanks for any help!!!
