If you do decide to get one of these make sure to get the proper seals (Dorman 56390) and also get a 1/4" compression to -4an fitting for the steam line. Also made sure to throw out the Allen head bolts and get some m6 x 1.00 30mm bolts to snug the fittings down to the heads. The Allen head bolts strip out way too easy ### ⭐⭐⭐⭐ Didn't get all the pieces *by B***I on Reviewed in the United States on 29 July 2024* You need to take your time to figure out which part goes where to get it to look good as there was no directions or indication on what tube to use for what side.I was also missing a fitting to connect the middle tube. I ended up getting a fitting locally and just running a longer rubber house.I can get around the missing directions. When doing a swap, "making it work" is the name of the game, however, not having all of the pieces is a major set back.Quality of parts received was very good. Used tread sealant on the standard side of the fittings. No sealant on the AN fittings which resulted in no leaks. ## Frequently Bought Together - PQY LS Coolant Crossover Steam Vent Kit LS 4 Port Steam Line Kit Compatible with LS1 LS2 LS3 LS6 Engines - WnSEu MSCRP LS Gen 3 Low Profile Valley Pan Cover Plate with Gasket and Seals Compatible with LSX LS1 LM7 LR4 LQ4 LS6 L59 - koxuyim Camshaft Retainer Plate Gasket Compatible with LS Series Engines, &Bolt Kit ARP 134-1003 Gen III IV V for GM LS1 LS2 LS3 4.8 5.3L 6.0L 6.2L Vortec Corvette Cam --- ## 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/547970494-ls-coolant-crossover-steam-vent-kit-with-coolant-crossover-pipe](https://www.desertcart.de/products/547970494-ls-coolant-crossover-steam-vent-kit-with-coolant-crossover-pipe) --- *Product available on Desertcart Germany* *Store origin: DE* *Last updated: 2026-04-25*
