It's useful for restoring proper coolant venting on stock or mildly modified LS intakes, for replacement of corroded OEM fittings, or for builders who want a corrosion-resistant stainless and aluminium vent path. If you own an LS1, LS2, LS3, LS6, LS7, LS9 or LSX engine and want a complete 4‑port kit with multiple fittings and mounting hardware, this PQY kit offers a practical, serviceable option—just confirm port sizes and install only on a cold engine.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does this kit fit my LS engine model?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: The PQY kit is designed for LS1\/LS2\/LS3\/LS6\/LS7\/LS9\/LSX engines but check port spacing and tube size before purchase.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can I install the kit with the engine hot?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No. Install only on a cold engine to avoid hot coolant burns and pressurized steam hazards.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"PQY","offers":[{"title":"Default Title","offer_id":48083250970782,"sku":"B0BVVJ4VX2","price":54.48,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/pqy-front-packaging-ls-steam-vent-kit.jpg?v=1785829716","url":"https:\/\/northtrailauto.ca\/products\/pqy-ls-coolant-crossover-steam-vent-kit-4-port-complete-stainless-aluminum-universal-ls-fit","provider":"North Trail Auto","version":"1.0","type":"link"}
