I found the package that the block heater came in - I put the parts that came out of the 4500 in it when I installed the heater. It is a Kat's frost plug type heater/block heater and has a Kat's part number on it. Part #11409. I looked the part up in a few auto parts company's on the web and the price is $24.99. It is listed as 400w - 120v. This should be universal across the "00" series Mahindra's. The only part that has to be bought from Mahindra is a different water drain plug housing - Mahindra part number is 006000385 F1, and water drain plug gasket - Mahindra part # 000020495 E05. Installation is relatively simple but the plastic cover over the starter has to be removed during installation and replaced afterwards. I
cut a notch in the plastic cover to allow the cover to lay in it's original position because of the power cord on the heater. I don't think Mahindra would want much more than $25.00 or less for the 2 parts making it a $50.00 job at worse case scenario. I hope this helps and answers any questions. I'll try to answer any questions you might have.
