Bought this for my 2001 Discovery 2 – Works just fine and saves you about $200 over the “Land Rover Genuine Parts” version and i’m sure that this is the exact same part and mfg.

I installed this unit on a 2002 Silverado with the 4.8L V8 Vortec gas engine and i have to say it really does make a difference in starting when it’s cold out. I live in the Midwest and last winter we had some single digit days with -25+ windchills and the truck seemed to definitely turn over quicker. I know for a fact helps keep the wear down on the engine with the warmer oil and block. The heater is probably as powerful as it can get for a small block like that but it would be nice to have it a little more powerful heat wise but it does get really hot! Don’t ask me how I know😂. Really good buy I don’t regret it!

I originally thought that the install would be much more difficult than it was. Truck never had a block heater since new (USA truck imported into Canada). Installed it into freeze plug just ahead of the starter, easy to do. No leaks works perfect!

Arrived fast & functioned OK

Dead out of the box, for both of the ones I purchased. QC is complete trash. Don’t waste your money.

In Alaska. My previous same brand Block heater shorted out after 18 years use and 110,000 miles on the vehicle. I removed the old one very, very easily, which surprised me, and quickly installed the replacement. Torquing it properly with no leaks afterward. However. the previous plug in cord to the heater itself pointed down and away from the exhaust header. The replacement cord once plugged into the heater pointed upwards, and NO I did not install the heater upside down, it was pointed to the 6:00 position as per the application, and the direction of the old heater . It WAS the cord plug in at the block heater direction. So, I just opted to reuse the cord already in place and kept the other cord as a backup. I could have used the new cord, but there would have been a semi-sharp bend in the cord to point it forward and away from the exhaust manifold, which would have worked, it was just my personal choice. It has been a week of using the vehicle after the new heater installation and No Leaks. Ex-Jet engine mechanic.

The element of the block heater is too tall to fit into the engine. The old one is about 1/4 inch shorter than this one.

The price for this item was awesome. Brand new product in a sealed original package for just over half of the price that the 2 auto supply stores in my town wanted for the identical item.

Love to hear it turn on when I plug it in. This January, we had a few -30 evenings. I plugged this in on my old van and, “varoom!” It started right up.

Leaks on 1985 Ford tractor, model 1910.I never claimed to be an expert at anything, but Ive installed block heaters several times without issue. O ring was not thick enough, so I used water pump gasket sealant, still leaks. Hard to say if its a poor fit, or poor product. Either way, if youre purchasing for ford tractor, expect a leak, even with proper preparation.Now that it’s covered in gasket material, I can’t return it, or use my tractor. But that’s typical Amazon. Stand by what you sell.Only reason for two stars is because it definitely gets hot.
