This is a non-transferable warranty unless Heads Unlimited’s Customer Service Department is notified in writing and the vehicle is in service for no longer than twelve months and the fee set forth below is paid with all transfer information properly completed. Heads Unlimited does not assume responsibility on behalf of the installing dealer, their technicians, and parts transferred from original engine, or unauthorized repair work. Additional installer and owner’s obligations; after engine has been driven for 500 miles engine oil and filter must be changed. It is mandatory that all engine fluids be routinely changed, maintained and checked for proper levels as described within. It is also mandatory to change the oil and filter every 4,000 miles according to O.E.M. specifications. All costs of these services are the owner's obligations and should be documented with strict repair or maintenance records. Engine coolant must be maintained and checked for proper levels and protection. Coolant must be changed every 24 months or 30,000 miles or which ever comes first. Warranty will not cover rotted freeze plugs. Warranty information must be completed and mailed to Heads Unlimited within 14 days after invoice date. Installing shop and owner of the vehicle must accurately fill out all warranty information and retain a copy of the warranty.
