Heater Core Replacement How to ?

Well i finally want to replace my leaking heater core . i have had it by-passed for 6 months now . and now its cold and i need heat . So , I heard Two Things 1. You have to remove the entire dash . 2. you can just remove the glove box and heater core cover and etc . Which is true ? which way should i go about this ? about hgow long does it take ? etc ?

also i have a 160 deg thermostat how will this affect my heat ?

You don't have to remove the dash. All you have to do is remove the glove box. Remove the rounded cover from the heater core housing. In the engine bay, loosen the two heater hose clamps and twist off the heater hoses. Then under the dash unbolt the one bolt that holds the bracket to the heater core and pull it out. I don't remember how long it took me.

Get a Haynes manual! Best tool ever for any car you ever own.

I would debat that , but what 94Z28WP is about all you need to know. There is a clamp between the heater core pipes at the firewall that you will also need to remove.

ok . I took off the glove box , took off the cover and one bolt holding the heater core in , and then it started to rain again , but now it seems all i need to do is the clip holding the core in . Shoebox where is it ? i did not get a chance to look since it stared frezzing rain again , how you get as far as rain or ice in little rock ?

Unplug the wire and then you have to just twist it out some kind of way. Doesn't really matter if you bang the old one up trying, just remember what worked and ease the new one in the same way.

the 160 stat does a lot for your heat. My car really doesnt warm up now and the heat is ok, but if the interior is cold to begin with, it takes so much longer to heat up now.

When replacing mine, it was straightforward as the Haynes manual says, though the old one was pretty beat to S*** when i finally got it out, the new one had to go in and come back out a couple times, and im not sure for what, but i remember putting it in the space, and having it wrong somehow and haveing to take it back out, just be patient with it and it will go well.

good luck

ok i got the old one out and put the new one back in . i just had to put more yhought into it . pretty easy might i say , my new heater core is a brass-copper one and seems alitlle wider but fits and works good . thanks for all the help .

also the 160 deg stat does make my heat no that hot at all . maybe ill switch to a 180 deg stat for winter and 160 for summer , but it does the job for now , but will never be hot air out the vents just warm . Thanks

p.s. i bought a used haynes manuel for $9.35 of ebay shipped
