Take out the glove box and there's a cover right behind it. pull the cover and core should slide out.

If you have A/C then pull the glovebox & the cover , then the core comes out in the cab.

If you don't have air, you must pull the whole heater assembly out in the engine bay. The worst 2 bolts are on the bottom. I always remove the screws at the back of the plastic inner fender, bend it out of the way & get at the bottom bolts.

Make sure you get the correct core, the High Output heaters have a larger core.

Got it out [cheers] whoever replaced it before (with a second hand one from a wrecker and it looks like it has been leaking for a long time before it blew:mad: )used sealant and used nut and bolt so the heads of the bolt spun (I broke one small part ) the heater says high output .
