I purchased a C5 coolant reservoir to free up some space for the turbo setup. I have a few questions though. The tank has two fittings in the bottom and one at the top unlike the truck tank which has the drain to the waterpump, a line from the radiator and a vent. It seems the C5 tank may be vented at the cap, if this is the case can I just run a line from the radiator to the top fitting on the C5 tank, the draim to the pump on one of the bottom fittings and then cap the remaining fitting?

Also, the C5 coolant level sensor uses a different connector. Is they anyway I can bypass this by grounding the factory coolant level sensor wires or do I have to buy the C5 sensor pigtail and wire that up? I don't really want to constantly deal with the low coolant indicator being on.

 

Grounding the sensor wire will turn the light off.

Sounds like a plan for the hose routing.

 

Well, glad to hear I at least have a rough idea of how to problem solve.

Thanks for the help!

 

The second coolant port on the bottom facing backwards goes to the top nipple on the passenger side of the radiator.

The top side port on the tank vents to atmosphere in the case of overflow. I have a line on there going to the posterior wheel well area.

I have the coolant level disabled in the tune

 

Do you have a picture of how you have it set up? I think I understand what you are meaning, but want to confirm.

 

After reading a few diagrams I am wondering something new. Our trucks have the Y-Hose that I believe acts as an incoming coolant hose to the waterpump. It splits off from the heater core and the coolant tank.

If that is the case would it be possible to eliminate the Y-hose and run the return from the heater core into the coolant tank and then just a single hose from the coolant tank into the water pump. If I am reading the diagrams correctly this is how the C5 system works and would explain the extra fitting.

 

Sure, should work. There will be a lot of activity in the coolant tank doing it that way.

 

That is the only thing I was worried about. Any reason for that to be a concern? I suppose if nothing else the constant bubbling would probably get annoying.

 

I dont think so...

 

Sorry, dumb questions. Well I guess I will run it this way and we will see how it goes. Thanks for all the help.
