Coolant leaking inside my car

[mattgo]

I finally found where my coolant was going. I took my carpet mat out to clean some dirt and I noticed a small puddle of coolant soaking up my carpet on my front driver's side. My dad said the heater core is cracked or something. What do you guys think? How hard is it to replace the heater core?

thanks

yep, deff. the heater core.... just to give you an idea of how much you have to take out I attached some of the pics when I did mine. I know it looks like a lot, but if you just take your time and when you take bolts, nuts etc off put them in seperate baggies so you know where they came from its not that hard

Yepp your Heater Core is probably leaking and need to replace it.
Not hard to do, just takes a long ass time.

wow, umm...I had no idea it was that much work. I might as well replace my broken dash too lol.

 

[mattgo]

how long does it usually take if I'm taking my time? Will it take longer than a day if I start around 9:00am-ish?

Poor thing! Best of luck with it!

And yes, replace the dash

It would probably take about 5 hours

Don't assume anything... After pulling my engine for my 5 speed swap, I had a slow leak on the driver's side. It turned out to be a loose hose clamp on the engine side of the firewall that was somehow causing a leak into the cabin - not the heater core. Weird, but true and definitely worth checking out before diving into a heater core swap. Here's the thread I started at the time:

Pretty well remove EVERYTHING from the windscreen to the seats.....

Shit of a job

Before you start, make sure it is not just leaking at the hose outlet on the firewall. Coolant can run down from that connection into the dash. I would hate to take the dash out to find it is just the hose connection.

^^^ that's what I was getting at.

If you've never done it before, start early on Fri. night and hopefully you'll be done Sunday about 4 or 5 am. At least thats how long it took me. Or get buddy to come over and do it, since he figures 5 hrs. Christ, it takes 5 hrs just to crawl over the piles of crap in there.

me and my dad will be working on it, We're starting after church on Sunday. We still got to fix the transmission on my truck first.
