I think www.dieselgiant.com shows the lower heater hose engine/block heater.

I didn`t see the block heater or radiator hose heater in either FastLane or Allpartsexpress.

I think zero start has the tank heaters that splice into the heater hose.

Lower radiator hose heaters are typically far cheaper on Ebay than at typical online parts suppliers.

I got a lower hose off Amazon for my Courier last winter. It worked ok, but there are posts on here saying that that type of heater is not recommended for these engines as the coolant can't circulate with the thermostat closed, or something along those lines.

I installed a in hose heater from www.dieselgiant.com about a year ago. And I wouldn't go another winter without one. I live in Centeral Texas, so it doesn't get that cold. But still the car is warmed up to 75-80 degrees after being on 3 hours. It allows the car to start up easier and I can switch over to wvo faster.

Great product for the cost, dieselgiant will also just sell you the heating element if you don't need to replace the hose.

Not true in my experience. The lower radiator hose does not heat up the engine as quickly as the OE block heater but it is an effective engine heater. I'd always choose a lower radiator hose heater over removing a block heater.

Kerry is right on the money. In my research in block heaters, I found that it would be very costly and prohibited to install a block heater on a 20+ year old car. I was informed it would be be better to install a new lower radiator hose and heater.

Out of curiosity, how do you test a factory block heater?

Can you put a DMM on it and it should read X ohms? Surely there is an allowable range, right?

I know the obvious test of after it's plugged in for a couple of hours the engine will be warm

I guess this is for guys like me where it is still in the mid-upper 90s and would like to do some preventive maintenance.

Well, it's about 400W, so it should draw about 3.3 amps at 120V. That should correspond to about 36 ohms.

I put in a block heater in my 300CD when I owned it. Installlation of the block heater was a PITA. I could not get the threaded plug out to install the block heater. I took it to a shop and I thought the guy doing the install was going to explode while trying to get the plug out. He had the allen wrench in the plug and a 6 foot pipe silpped onto the allen wrench, he had all his energy on that pipe before it finally moved. I had tried impact guns 3 ea and 2 air compressors without any movement at all. Those plugs are in there very tight after 20+ years. I opted for the lower radiator hose heater for my 300SD.

there is a pictorial on here somewhere about a guy pulling the plug and installing a block heater...
hose heaters do work ok.

If your existing block heater isn't working check continuity of the cord before you rush to condemn the heater itself. These cords are prone to failure after being exposed to the elements for years, especially up here in the salt belt.

FWIW, I just checked both of mine.

240D (cold) = 36-37 ohms

300D (warm) = 30-31 ohms

IMO, anything in that area will indicate it's OK.
