If you are talking about the 90 degree plastic elbow coming from the belt tensioner housing.......first loosen the belt and take it off ( remember the routing on it) and then remove the two little nuts holding the coolant overflow bottle ( you don't have to disconnect the hose....just set it over to the side so you will have room to work). Next remove the bolts holding the alternator and set it to the side.Now the fun part. remove the 4 bolts holding the belt tensioner housing to the block. Once those are out you can pull the assembly forward and the elbows should come with it. The elbows are held in by o-rings and should just pull out. remember to replace both of the 90 degree elbows at the same time ( might as well so you don't have to do it all over again). Assembly is just the reverse of the above. FYI these elbows break so often that you can now buy replacement ones made of metal at www.rockauto.com and they are only $4 more than the plastic ones. I replaced these 5 times before I'd had enough and went searching. Seems that this piece of plastic breaks quite frequently when the vehicle hits a dip at speed.Hope this helps.

Cool car down and drain the radiator, usually a spigot or valve at the bottom. remove the clips or clamps holding the hose on, pull hose off. get a new hose from any parts store, sometime helps to have the old one with you. install new one, put on new clamps and tighten firmly, pour in new coolant. check your owners manual to see what kind of coolant Buick recommends.

Where is the heater control valve on a 2005 Buick Lacrosse?

It sounds like the heater control valve may be stuck. This valve allows heated water from the engine to pass through the heater core which in turn heats the inside of your car. If this valve is stuck, only a small portion of heated water will pass through. If this is the case, you should have the control valve replace.

You should be able to find it by following the heater hoses coming from the radiator leading back to the firewall. These hoses will about 1/2 - 3/4 of an inch in diameter so you shouldn't get them confused with the normal radiator hoses.

You can probably purchase a new valve at an auto parts store but I'm sure the dealer will have one.

If that's not the problem, it could be that the core itself is clogged up. That's a little more expensive and more of a pain to replace. if this is helpful please dont forget to give rateing thank you
