For my 2023?** A: Not sure which model vehicle you're asking about since this heater hose fit on the older Pathfinder, Frontier and Xterra. Being that all the 2023 models are completely different than the older 4.0 I would assume not, but I'm also not aure which country you're in and what models are available to you. **Q: Question i read that it says without rear heating and ac? what doea it mean? i have a 2007 pathfinder 4.0** A: I bought this for a Nissan Xterra 2006 it's a small suv but does have heat and air but doesn't have a second ac in rear only vents coming from the front to the rear hope yhis helps was the exact part. **Q: Would this fit a 2007 nissan pathfinder 4.0?** A: I really would not know about your vehicle. Might be best to contact your Nissan dealer, get your specific part number and verify if it will fit your vehicle. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect fit *by on Reviewed in the United States April 9, 2026* Exactly what I needed to repair the Xterra. It's better quality than the original, no plastic fittings to split and leak. The new one had little clips that hold the band clamps open for easier install. It made for a fast replacement. ### ⭐⭐⭐⭐⭐ Good upgrade *by on Reviewed in the United States May 26, 2026* Perfect fit. Definitely an upgrade from the original OEM one. ### ⭐⭐⭐⭐⭐ Exact Replacement for Nissan's Stupidity *by on Reviewed in the United States November 24, 2021* The OE Nissan heater hose has a plastic tee molded in ( non-replaceable ), that cracks & then leaks when it gets age hardened and brittle. This Dorman piece is great, direct drop-in replacement but all rubber and metal, no junk plastic moldings. You will need to replace the spring clamp at the firewall side, with a stainless steel aircraft worm gear clamp, as the spring clamp they supply has an installation "holder" tab that's supposed to be removed to let the clamp relax into place. However, this doesn't work as the tab hits the AC line that's just above the heater outlet pipes. A minor nit to pick though here, really, as the rest of the assembly is top-notch and should last the life of the truck.I gave the assembly itself a 4 star for installation due to the mentioned tab above, but I give Nissan a 1 star for making the OE assembly such junk, and then making it so so so difficult to field repair. Be prepared to lay on top of the engine cover while attempting to wrestle off the OE spring clamps, they were obviously put in place before the engine went in, as getting them out is a nightmare. I ended up using a water pump pliers, another needle nose pliers and a specialty spring clamp pliers set ( another king Jeffrey of AmazonWorldLand purchase ) to work these little buggers outta place. So be warned, and be prepared.You will need to replace both fittings at once, as getting this one off without removing the other heater extension, is well nigh impossible as well as I could see. And that one contains plastic as well, so do 'em both at the same time.You will also find threading this assembly back through behind the engine will be a huge challenge as there is a large wiring harness back there, that I got hung up on, five or six times. It was an exercise in patience, for certain. ## Frequently Bought Together - Dorman 626-598 Engine Heater Hose Assembly Compatible with Select Nissan Models (OE FIX) - Dorman 626-610 Engine Heater Hose Assembly Compatible with Select Nissan Models (OE FIX) - Continental 64326 Molded Heater Hose --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.de/products/321246077-dorman-improved-design-626-598-engine-heater-hose-assembly-compatible](https://www.desertcart.de/products/321246077-dorman-improved-design-626-598-engine-heater-hose-assembly-compatible) --- *Product available on Desertcart Germany* *Store origin: DE* *Last updated: 2026-07-25*
