Block Heater

Gooseneck8 · Monday at 4:21 PM

I have a Massey Ferguson 1533 I bought new in 2006. It has an Iseki diesel engine. I want to install a block heater (part #3605426M92) but I have not found a video to show me where and how. Anyone have information? I surely would appreciate it. Thanks.

2008 MF1532 has it going in right side front water jacket, unsure of 1533. but the common factor is drain coolant, pull whatever water jacket plug to be used, clean area VERY well, install heater in place of plug using sealant.

Thanks, I'll check it out.

should say I THINK its rt side fwd, tractor not on site right now. seem to remember its opposite my GC2400. really any of the water jackets you can easily access would prob work.
but rest of post stands. may be good idea to double check with a dealer.

Take a look at the Massey parts book: MF 1533 and type "heater kit" into the search box. There are several based on serial number, so take a look. The navigable schematic should help you with the install location.

was at dealer yesterday (1-20-2026) and they had just released a 1533 to customer for block heater install. actually block heater replace. customer left it plugged in full time and burned it out.
was not able to get pics but block heater goes on right side (as sitting on tractor) on the most fwd water jacket port.
attached is pic of block heater on my 2010 GC2400, position is not the same on a 1533 (this is left side of engine as sitting on tractor) but it will show how the block mounting bolts used work.
my pigtail is orientated upwards then loops down then up to plug in, yours WILL be different.
just keep in mind these are NOT thermostatically controlled. once plugged in they run full time. which is why that 1533 was at dealer for block heater repair....

edit:corrected spelling issues and clarified stuff.
