I have a 1999 taurus and there is a tee at the rear of the motor that the heater hoses connect to. There are permanant fittings on the tee. The tee has a hole in it. Can I just cut the hoses and put a tee in its place?

Yes, they sell nylon barbed heater hose fittings in a tee. After cutting hoses & attaching to tee with hose clamps. Take zip tie or wire & attach it to bracket for support of hose.

How do i change the heater hoses

If they're not leaking you don't. If they leak at the plastic tee's, just cut the tee out. Go to the hardware store and buy a barbed tee, 5/8 or 3/4. and three hose clamps to fit. Why spend $50 for the hose, when can repair them for $10.

Heater core leak. How can I temporarily bypass heater core?

Purchase a hose mender or flush tee. Find the heater hoses under the hood. They will be on the passenger side of the engine and should be 5/8 or 3/4 I.D. hoses. Cut both hoses and install the mender or tee in between the two ends that go to the engine. Usually on hose is 5/8 and the other is 3/4. buy one of each size fitting and try to stretch the 5/8 hose onto the 3/4 fitting. If you can't, when using the smaller one, you will have to tighten the clamp extra tight when fitting the 3/4 hose on the 5/8 barb. get yourself two wormgear clamps in either case.

You just need to get the engine full of coolant. Disconnect the drivers side hose from the tee and fill motor full of coolant with a funnel until it starts running out of tee.while its cooled down.

Heater hose leaking at the tee. I need to know how to access the hose to remove and replace?

If it's the hose I'm thinking of, it is called the octopus hose and is one complete part @ $150. It is upper radiator hose, coolant bottle hose, heater hose all in one.

No heat thermostat isopening and closing andfanis working sometimes you get a little barley warm air then it goes back to cold air also ck. eng. light is on

Ck Eng light probably not related.
The heater core is clogged. A bottle of cooling system "quick flush" may be all you need ($6 AutoZone).
There is also a complete flush system, but requires that you splice into the heater hose (I installed it on my Taurus - works great!).

By the way, there is a heater core bypass hose. It is connected to the two heater core hoses near the firewall. You may want to remove the two "Tee" fittings and use a 5/8" hose splicer so that the flush passes through the heater core at full force. Put the Tee's back in place after the flush.

If you remove the tee fittings and don't flush, the heater will work, but the core may eventually start leaking.
