Default How 2 install a engine heater on my Ranger?

I purchased a Kats engine heater. It is the type you splice into your heater hose. Haven't had one of these for years but it seemed like it would be an easy install. That is untill I looked under the hood!! This is much different than the old 70s & 80s cars.

With the heater valve being vacuum controlled will this type of heater even work?

I know a block heater would work but I wasn't wanting to hastle with trying to get to & remove a freeze plug to install the block heater.

i don't know for sure as i have no experience with these, but my guess is as long as you leave your switch in the truck in the full heat position it oughta work, i'm guessing that it circulates the coolant as it heats it?

Yes it circulates the coolant as it heats it.

ok well then my guess is when you need to use it you should leave the switch in the truck on the full heat position when you shut it off, then the coolant valve should stay open and it will be able circulate through the system, again i have no experience with installing these, just taking an educated guess here, good luck with the install though

Yes the heat valve needs to be open. That's my concern. Vacuum pressure holds it open. Will the vacuum bleed off overnight? If it would close, the heater will burn up.
On the older vehicles the heater valve was manually operated via a cable.
It gets installed in the heater hose that comes from the water pump.

The temp knob on the HVAC panel does not operate the valve to the heater core. The temp knob manually moves a blend door by cable. The valve on the heater core is only operated by putting the HVAC control to MAX AC. I believe it even remains open with the control set for off but someone should confirm that. I also don't think it vacuum pressure that holds the valve. I think vacuum pressure simply moves it between open and closed. So a loss of vacuum pressure shouldn't cause the valve to move. This should be easy to test if you can access the valve. Just pull the vacuum line and see what it does.

As long as the valve does spring closed with a loss of pressure, then just make sure the HVAC control is left somewhere other than MAX AC (and maybe off).

Engine vacuum closes the water valve to the heater core in the OFF and MAX A/C positions only. The valve is spring loaded to open in all other mode selector positions.

Didn't your truck come with a heater already?

Mine has it, and I know it a must for cars up here, I think they are required to have them.. Must not be affect for you in Iowa?

Yes my truck has heat. The heater I'm wanting to install warms & circulate the coolant.

So overnight when it's cold as shit out. You plug in the heater which makes your engine easier to start, warm up to normal temp quicker.

Duh.. Sorry I wasn't clear.. I meant a block heater, not a cab heater! LOL

I have a garage, so not a big deal for me.

Nope no block heater. I have a garage also. It's just not big enough. My mustang & my wifes Toyota have the garage. The ranger has to tough it out outside.

Ranger's can tough outside! they're big and strong! mine does too.
But I was just wondering about the same thing for this only I have a magnetic type heater that I was wondering where I should place it for the winter if I were to use it?
I know i didn't start the topic but any help would be great.
