Block Heater - Toyota 4Runner Forum

fathousecat_ · 11-21-2021, 07:05 PM

Hello,

I am looking to install a block heater for the 5vz-fe. I see Katt's are out of stock. What are some other good options?

Thanks!

I vastly (no, seriously, *VASTLY*) prefer a coolant heater to a "block" or oil heater. I've run a 'zerostart' brand for 17 years without failure or issue. Plugged it into a timer so that roughly an hour before first use it'd come on and heat. Worked amazingly, even down to -40.

Amazon.com: Zerostart 3309043 Circulation Tank Heater for Power Generation, Compressors, Agriculture, 3/4" Diameter Inlet/Outlet | cCSAus Approved and cULus Listed | 120 Volts | 1500 Watts : Automotive

That's basically the unit I ran, and yes there's some plumbing work involved, though there are some styles that replace a small section of the lower rad hose.

Having grown up in Wyoming with the other typical block heaters, I'll never go back to them.
That's basically the unit I ran.

Thanks for this. Out here in Eastern MT we get -30s for a straight month atleast.

having used the "Katz" brand and the toyota one, the toyota one is better.. Easier to install ( the bend is tighter so it goes in easier) and the anchor bar is better.
that said , they can go bad, and they can develop a leak with age...either brand.

I know all about that.

Born/raised in Wyoming, college at MSU Bozeman (met friends from out on the eastern side of the state), folks retired to White Sulphur Springs, MT. The beauty of the coolant heater was that you had instant Cabin heat too... just don't leave your radiator open/uncovered or you'll dump all that heat in an instant.

I have them on the 4runners, but have never used them. Yes, I also live in Eastern Montana. I think -32F is the lowest I have seen here. The engine just took a couple more times to turn over.

Not such a small world after all.
