Lower radiator hose diameter and block heater

Looking to add a hose heater to my truck since it's going to be frigid again this week. Anyone know the lower radiator hose diameter on a 2.5 petrol? It snowed again and I'm too much of a sissy to go measure.

Also want to know the correct Napa version/ size of the block heater to get- goes in the freeze plug. Believe that the one for a 2.5 Diesel will fit too. RN has the part but doesn't list the size so I'm not sure which size to get at Napa.

If anyone has the corect part numbers for Napa I'd be super stoked.

Looking to have one warmer truck this week.

Thanks,
Alex

This sounds like the same freeze plug heater that I fitted to my 300tdi. Although mine was a 400w not a 600w
Be careful installing it, I have head trouble with mine due to overtorqueing of the butterfly screw. They do provide a torque value, suggest not exceeding that...

"Just wanted to update for the record - I ordered a Zerostart (aka Temro) 600W 'freeze plug heater' P/N 3100087 and it fits. I had to use the middle core plug (the front one is partially obscured). Size is 2.06in (52.3mm) - it's in the agricultural section of the application guide under Ford"

The bottom hose diameter should be 1 1/2". Rovers North has the hose heaters on sale right now. This one should be the heater you're looking for:

It's a lot easier to use an oil pan heater. It just gets adhered to the bottom of the pan.

They do not provide enough heat input. I would also argue that it is less work to install a lower rad hose heater.....

Probably. You could walk to your own truck and measure...faster than posting to these forums. A lower rad hose heater should be available at ANY auto parts store where it is cold enough to need one. No need to buy via Rovers North....

I prefer a block heater, but I'm putting that off.
I have one of these;http://shop.wolverineheater.com/ and it works great.
Unless you don't have coolant in your truck, there is no way a rad hose heater is quicker. The Wolverine takes about 5 minutes to install.

Well, to do it "right" you need to thoroughly clean and sand the pan first.

They do not have enough heat, unless you live somewhere that really does not need one. I've had one for years, so this is first hand.

I'll have to look and see if anything is printed on the unit. It's a generic one for a 1.5" hose.

The latest Rovers North News states that this heater is for "Late Series IIA and III, Defender V8 and TDI". Double check that your hose is 1 1/2" and it should fit.

As mentioned, your local NAPA might have something as well.
