Re: 98 Blazer heater core replacment (I just did it)

I bookmarked this page a while back when I started to smell a slight hint of antifreeze inside the car. It finally decided to spew antifreeze everywhere, so this has become THIS weekends project! I printed the first portion out, as well as relevant comments, and would like to add my own $.02 fron things that would have been helpful.

First, if you have no patience, save yourself a headache and take it to get repaired. I'm not looking to set any records so I am taking my sweet time. I am actually just about to take the cover off the HC. I may be cursing once that is done, however!

Yes, there are approximately 6 main bolts. BUT no one mentioned the multitude of OTHER bolts to get to the 6 or so main bolts.

1) I used a 9/32 on most of the screws, and 10 mm on the main bolts. Having a swivel socket makes ALL the difference, at least in the dash removal.

2) I scratched my head when I got to the bracket in the steering column for quite some time because there was no clear way to get to those bolts. Then I noticed that there were 4 nuts holding up a steel piece just under the steering wheel. I took those off, and getting to the 10 mm bolts was cake.

3) When you take just about everything imaginable off including the glove box, and the dash STILL wont move, don't forget the 4 screws in the defrost vent. They will loosen it bigtime.

I will take pictures and submit links when I am either cheering that its all done, or flustered because I'm still trucking along!!!

And another thing... yes, its not much fun, I will say that, but I am female and moving right along thru this! Just taking a break, getting some weather (murphys law, right?)
