Editorial Policy & Research Standards
Our goal is a useful answer that remains honest about uncertainty. We favour primary documentation, exact identifiers and safe next steps over generic winter advice.
Source hierarchy
We start with current manufacturer application guides, owner and service manuals, official parts documentation, Natural Resources Canada vehicle data, Transport Canada notices and recognized electrical-safety guidance. Retail listings and forums can reveal a question, but do not overrule primary documentation.
Review standard
Safety, voltage, fitment, wattage and installation claims receive the closest review. A page must distinguish a confirmed application from a universal workaround or an Amazon search suggestion.
Commercial independence
Affiliate availability does not determine the recommended heater type. Affiliate links are labelled, use sponsored link attributes and may earn the site a commission at no added cost to the reader.
Updates and corrections
Material changes should update the visible review date and sitemap date. Credible correction reports are checked against the underlying source and corrected promptly; the page should not look freshly updated when only an unrelated deployment occurred.
Safety boundary
The site is educational. Current manufacturer instructions, applicable electrical rules and a qualified technician take priority where coolant, mains wiring, fuel or an uncertain engine port is involved.
