How do you replace a heater core in oldmobile 88 royale?
It's not a job for a novice-it's in the dash so the whole thing has to come apart to get to it. You can see where it is by location of hoses on other side if you want to try it. Until it is fixed, you can couple the hoses together to bypass and still use the car. Everything but the heater will work.
How can you bypass the heater hoses on a 1998 Ford Expedition?
all you need to do is disconnect the hoses from the heater core first. this may be somewhat difficult depending on mileage and how well the cooling system has been taken care of. but i assume it has not because you obviously have a heater core leaking. after you get them disconnected cut off the two ends and insert a plastic or metal pipe of somesort and install the ends of the hoses onto both ends of the pipe. then install two hose clamps on both ends to seal them. now this will ruin both hoses and they will need to be replaced upon replacement of the heater core. also this will not cause any problems with the cooling system by doing this. you do not even have to worry if the hoses are kinked at all. the coolant will still flow through the engine just fine. On my 2000 expedition , there are quick disconnects at the hoses going into the fire wall. There is a special toll to disconnect them, but most times you don't need it. this will save your hoses when putting back a new heater core. NOTE: I did not answer this question. I just added the part with the quick disconnects,,,Tom Wade...

Can you drive a truck if heater core is out?
yes. You would need to bypass the heater core in order for your coolant to still circulate properly. Check with your locat auto parts store. Some stores actually sell a bypass hose designed for this application. If not, you just need to connect your inlet and outlet hoses at the heater core together so it will circulate. Most auto parts stores will have a barbed fitting to connect them.
If I bypass the heater core will the rear heater still work in a 1999 ford expedition?
Well … These are the two answers I got from other websites. Regarding; if I bypass the heater core will the rear heater still work 1. It depends if they have the optional rear heat/air. If so they have 2. 2. My 94 E-150 5.8L with optional rear seat Heat & A/C had a separate unit under the chassis - just about where the 2nd row started. I figure I would share them.

In your truck when you switch from cold air to heat the air still blows cold?
Interior heat uses the engine heat. If the engine is still cold, the heater will blow cold. If the engine is warm and the heater is blowing cold, you have a problem with the heater. Check the water in the radiator and see if it is rusty. If it is rusty, change your coolant, thermostat, and hoses. Look at the heater hoses when someone steps down on the gas pedal. If a hose collapses, replace your heater hoses. Otherwise take it to a mechanic.
Can you still drive your car without the heater core?
Yes, as long as you connect the incoming and outgoing heater hoses that were connected to the heater core together. You will not have a functioning heater or defroster but otherwise it will be fine to drive.

Is there a way to band aid a heater core leak without doing further damage don't have the cash to fix right now but need to use car?
Yes. Connect the two heater core hoses going into the firewall together and bypass the heater core altogether. Cut a piece off a metal broomstick about 4 inches long and attach each end of the hoses to the cut tube and tighten the hose clamps. You'll have no heat in the car but the antifreeze will still keep your engine from over heating. Fix the heater core as soon as possible.
I have replaced the thermostat heater control valve and flushed the cooling system Why is heater still blowing cold?
With the vehicle warmed up and running feel both heater hoses with your hands. If one is hot and the other is luke warm or cold, the heater core needs to be flushed by itself. Flushing the whole system doesn't unclog the heater core. Disconnect both heater hoses from the engine, fabricate a fitting to attach a garden hose to one of the hoses. Direct the other hose into a container and gently turn on the water until the water runs clear, then reverse hoses and run again until clear. Reattach hoses to engine and refill reservoir.
Replaced thermostat and still no heat in my VW Golf?
This is a common complaint with mk2 Golfs, most of which were fitted with a heater matrix bypass valves to prevent the heater matrix from bursting under certain conditions. These bypass valves can fail, cutting off supply to the heater matrix resulting in no heat. Either replace the valves or remove them and fit a heater matrix from a mk3 Golf. These are stronger units and don't require bypass valves.
