How do you change a heater core in 1994 chevy astro van?
you need to take apart the lower dash on the passenger side. This is not a fun job.
Remove the dash, its located under the glove box. Becarefull it will puke out antifreeze!
how do you change the heater hoses on 1993 chey lumina 3.8 liter
remove old heater and screw in new
The entire dash assembly needs to be removed to gain access to the heater core. I would recomend purchasing a shop manual for that vehicle if you decide to do the job yourself.
If it's a v8 it will have a 5.7 liter 350
.the heater core is behind the dash .
It should say in the glove compartment. My 95 says 1885 lbs. With the 5.0 liter
