the hoses hook to the back of the engine one on the right and one on the left, best way to work on these is from the underneath.
Easiest way is to connect the two heater hoses together.
The easiest way to check is to feel the heater hoses going into the firewall. Check the hoses from a cold start and check that both hoses get uncomfortably hot at about the same rate. This is a good indication that coolant is flowing.
I would disconnect both heater hoses from the engine, then fabricate a way to connect a garden hose to one of the hoses leading to the heater, then gently turn on water supply for a minute, then attach garden hose to opposite heater hose and flush again, then reattach both hoses to engine and top off coolant reservoir.
In most cases no. The core flows both ways.
This will not effect the engine in any way
it doesn't matter man,if you cant tell were they go than just hook them upit doesnt matter what way it flows through the core.
I have a 94 Astro but the heater control valve should be in the same location. Look under the hood on the passenger side. There are two heater hoses behind the coolant reservoir and windshield washer reservoir. The hoses attach to the heater control valve. The valve has a round vacuum actuator on the side, and two more heater hoses leave the control valve and go into the heater core housing. Cost for the valve will probably be somewhere between $50 & $70 To replace it, remove the coolant reservoir and the windshield washer reservoir. Remember, or mark, the hoses for the washer if you have a rear washer. The electrical connections only go on one way. Remove the clamps securing the front heater hoses and remove the hoses from the valve. Remove the clamps holding the heater hoses coming off the back of the valve where they are attached to the heater core. These two hoses are factory attached to the valve and the new valve (from the dealer) comes with the hoses attached to the rear of the valve. The clamps are back in a small space behind the valve, rather hard to get to. We pulled the bracket with the three square relays situated above the hoses to allow easier access. Install in reverse order. Good luck.
Usually, with a plugged heater core there will be a bit of heat but not very much..I've only seen a few so plugged that there was no heat. One way to tell is to (carefully) touch the heater hoses just where they go into the heater core. Both hoses should be about the same temperature. If not and the heater control valve is open - then the heater core being plugged is a very good possibility.
there is not a wrong way to crochet, but there is a wrong or cheat way of holding the crochet hook, hold it like a spoon. alot of beginners hold it wrong. I have to disagree with the above answer. Some people hold a crochet hook "knife" style, the body of the hook held within the hand, and some hold the hook "pencil" style, with the shaft of the hook laying on top of the hand. Either is correct, or anyway you hold the hook is correct if the stitches are coming out correctly, and the hold is comfortable. Some people train themselves to use both holds or even either hand in order to decrease fatigue from holding it only one way. -smcm
Disconnect both heater hoses from the heater or the engine, whichever is easier. Fabricate fittings to attach a garden hose to one of the heater connections. I direct the other heater connection into a bucket. Turn on the garden hose gradually until all the way open. Flush for 30 seconds. Reverse heater connections and back flush another 30 seconds. Reinstall heater hoses, top off radiator coolant reservoir. Done.
