Anyone have a decent diagram of the coolant reservoir tank hoses? Was talking to my mechanic and we were talking about the coolant leaks, where I solve one issue, then a leak develops elsewhere, solve that and it turns up in a new place. Need the schematic of the coolant hoses. He thinks that pressure is building up somewhere (thermostat is new and opens/closes when it should), unless there are weak spots in the cooling system, where air is sucked into the and it blows out of the reservoir tank if I have more than 1-2 drive cycles when the engine is hot.

Vulcan.

Mechanic thinks that there could be spots that are weak, but also thinks that there could be unseen blockages or something amiss. He already has to warranty the heater core because that is leaking, but he thinks there are other cooling issues with it. Water pump was tested for flow and for leaks, which it isn't, thermostat is new and working, He knows that when I have multiple drive cycles when the engine is hot, it boils out the radiator cap, but there is a leak in the heater core, and he thinks that coolant rises in level, and spills out when it gets air to it.
