This being my about my 5th first Gen, I really spent some time looking for the right one. This truck was almost perfect, but I knew it needed a few things. Summer had officially arrived and the AC had not worked since day one. That along with a horrible smell of coolant had me jumping back on my truck the instant I had some clear garage space.
Fist off, the coolant smell. At first it was pretty minimal, had no effect on my running temps, and I could not find the source. On a 100+ degree day (with no AC) I finally noticed a leak coming from the passenger side behind the front tire. It was a little tough to see where the leak was coming from with the fender liner in the way, but I was able to spot the leak coming from a small tube under the heater box. Turns out, this tube is the extension of a drip pan that houses your heater core. Quick & easy $30 fix and the smell was gone. One note I would say is that the new heater core did not come with any insulation which helps it stay in place. Definitely run down to home depot for some stick on door installation for this install, and dont jam a couple rags in there like I did, lol. I also flushed my cooling system because as you can see, the heater core did not give up without spitting its rusty guts out first!
