I just hang thermostat in 1994 buick lesabre and still get no heat what can be wrong

SOURCE: doing a tune up on a 1994 buick lesabre

A full tune up consists of spark plugs, distributer cap. wires. rotor for under the cap, air filter and if you want you should change the fuel and oil filter. I hope this helps.

If this Buick has a 3.8L, there are air bleed valves that must be opened to ensure the cooling system does not develop an air lock. (Wich would cause a no heat condition). If the thermostat is functioning properly you may want to check if there is flow through the heater core. Check by feeling each heater hose at the firewall with engine at opperating temp. They should both be hot and close in temp. A noticable temp difference in the two hoses would most likely be a flow problem, either from an air lock, bad t-stat or plugged heater core. Good luck.

It could easily be running out of fuel - the fuel filter. And possibly the fuel pump. I would check the fuel filter first. hope this helps you, Rick

SOURCE: 1994 buick lesabre heater core removal

The heater core is located under the dash, in the center. The container holding the core looks like a black plastic box. Remove the ash tray for easier access. You may have to also remove some other covers under the dash. You must first drain the radiator then you have to disconnect the hoses. There are two hoses connected to nipples of the heater core that go thru the center of the firewall. Remove the screws that hold on the cover to the heater core. Then you should be able to get the old one out. There might be a couple of other minor steps but I'm sure you can figure them out. For re-installation just go in reverse order to put it all back together.
