It depends on the vehicle you have. In many cases (but not all) the inlet hose is smaller than the outlet hose.
Simply disconnect the heater hoses going to and from the heater, (Inlet & Outlet) at the firewall. Purchase the proper size hose coupling that will allow you to connect the 2 hoses together. Do not plug these hoses, just connect them together. The coolant will now not flow through the heater core.
The heater hoses are 5/8 inch diameter.
It hard to generalise, but.... Generally the inlet pipe comes off fairly close to the thermostat/water pump, and the outlet returnes the water somewhere not near the thermostat/water pump. start the engine and feel the 2 heater core lines the one that starts to get warm first is the inlet. As far as the heater core itself, usually the smaller of the two tubes or the lower one is the inlet. If they are both the same size and are side by side it probably doesn't matter.
Heater core is Bad Sounds like your heater core is the problem. you can bypass the heater core for the summer and be okay if you do not want to spend the money (or need the heater) till winter. There is an inlet and outlet hose for the heater core in the engine compartment on the passanger side. Go to your local auto parts store an purchase the correct size hose splice and simply connect the two hoses together. This will allow coolant to circlute through everything except the heater core.
There is none,there is a place for it but was never installed. Remove larger of two hoses at right (passenger side) of water pump. They are heater size hoses, Just remove the larger one from side of water pump.
Depends on the vehicle and somtimes engine size. B Clear.
Follow the two hoses (usually black) that are about the size of a garden hose from the motor. Those are heater hoses and lead to the heater core.
This question is a bit confusing. It needs more information. If it involves installing a new heater core, you will really need a good repair manual because this job gets to be quite involved, and is not one that I would recommend for the average do-it-yourselfer. EITHER CONNECT TOGETHER THE HEATER HOSES THAT GO 2 THE HEATER CORE WITH A 1/2OR3/4INCH STRAIGHT PIECE OF PIPE ORCONNECTOR - OR INSTALL 2 BLOCK OFF PLUGS WHERE THE HEATER HOSES USED 2 B CONNECTED ON THE ENGINE.
Very simple on that car. On the passenger side firewall you'll see two heater hoses running in. Remove the clamps and pull both hoses from the heater core. You'll lose anti freeze doing this. Either use a hose coupler the correct size or remove one of the hoses from the engine and mount the other hose to that location.
To determine the inlet supply for a pool heater, first assess the heater's specifications, including the required flow rate and inlet size. Measure the pool's total volume and desired temperature increase, then calculate the necessary flow rate using a pool heating calculator or formulas that consider these factors. Finally, ensure the existing plumbing can accommodate the required flow rate and is compatible with the heater's inlet size, making adjustments as needed.
What size engine do you have, I'm trying to be sure someone has correctly connected my heater hoses up right on my 66 428 w/air T-Bird
remove both hoses from the heater and join them with a short piece of pipe about the size of the inner diameter of the hoses. use 2 hose clamps to sealed and hold the hoses on the pipe. Or- cut the hoses and do the same type joining. later you will need another pipe and two more clamps if you want to rehook it to your heater core.
