Which heater core hose goes to the water pump?

Which heater core hose goes to the water pump?

The upper radiator hose is connected to the thermostat housing and to the radiator. From the bottom of the radiator, is the lower radiator hose that is directed to the water pump.

Where do the coolant hoses go?

The upper hose attaches from the top of the radiator to the top of the engine. The lower hose attaches to the bottom of the radiator to the water pump of the engine. If the radiator hose of your car fails, it can lead to loss of coolant and subsequent engine overheating.

Does it matter which way water flows through heater core?

No, it makes no difference whatsoever which direction the water flows through the heater core.

Does a water pump push or pull?

Depending on the pump design it can push, pull or do both. In reality, all pumps are pushers, since even a pulling pump (e.g., sucking water up a drinking straw) is simply removing pressure on the pump side so that greater pressure on the pumped fluid at the other end of the line can push it into the pump.

Do both heater core hoses supposed to be hot?

The coolant temperature should hit at least 160°, preferably 180° to 220°. If coolant temperature is acceptable, feel both heater hoses, which should be hot.

What happens when you bypass the heater core?

You basically take the two hoses off the heater core, you stick them together and you’re done. That way, the coolant will continue to circulate, even though it no longer goes through the heater core. And bypassing the heater core should have no effect at all on the performance of the engine, Charles.

Does coolant flow through heater core when heater is off?

If the system is not equipped with a heater control valve, coolant will circulate through the heater core when the heater is turned off. The easy way to tell if coolant is circulating through the heater core is to warm up the engine with the heater turned off and the temperature set to the coolest setting.

What happens if you get heater core hoses backwards?

By reversing the hoses, the coolant will flow in reverse direction through the core, but it’ll still be flowing in the same direction as far as the engine is concerned. This may not prevent it from carrying debris from the core into the engine cooling system.

Can a water pump hook up to a heater core?

Sounds as if your water pump was not designed to supply a heater core. All of my after market pumps have two fittings. The larger hose, I believe, usually hooks to the pump itself (suction side). Lets have a few more people give their advice. Why would anyone make a waterpump not compatible with a heater core?

Where does the water pump hose go on a Camaro?

The fitting on the intake manifold is the outlet, and that hose goes to the lower fitting on the heater core; the hose from the upper fitting on the heater core goes to the fitting on the water pump, which is the inlet. The intake-to-core hose is 5/8″ ID, and the water pump-to-core hose is 3/4″ ID.

Which is larger a return hose or a feed hose?

It seems I made a very common mistake by running the 5/8″ hose from the water pump and 3/4″ hose from the intake. I think the return line should be larger than the feed line simply; with the same Volume of a smaller hose will have higher pressure and a larger (return) hose will have lower pressure.

Do you need heater core to fill with coolant?

Bruce, it actually does matter, depending on the way the heater core is mounted in the housing, you’ll want the heater core to fill with hot coolant to get the most heat in the cabin, otherwise, the heater core will have little pressure or coolant to do it’s job.
