If it is anything at all like the old inline six in the Cherokee, I would send it back. It involves punching out a freeze plug and replacing it with the block heater, all by feel as the location was under the exhaust header. I blew 2 heaters literally out of the freeze plug holes, and then gave up and put a freeze plug back in, which is a very difficult job as it had to be done by feel. I'd go with a lower radiator hose heater instead or along that line. By the way the block heater looks like nothing more that one of those old water heaters used to heat up one cup of water, with a brass plate and o-ring.

Anyone install an OEM engine block heater in their 3.7L? I ordered one off the web thinking it wouldn't be so difficult to install but the instructions (vague as they are) looks like the entire engine compartment needs to be disassembled just to get to the cap where it installs. Anyone have any experience or thoughts on this. Thanks.

. We only get about 30 inches of snow all winter. Winter of course for us runs from Oct to April. And we have only about 4 hours of daylight in Dec because we are so close to the Arctic circle.
