These heaters are very common in our country and are also installed in many smaller cars with smaller batteries.

Thanks to the preheated engine, the starter motor also requires significantly less power to start the engine, which naturally puts less strain on the batteries.

this is my daily driver before and after



Nice K5 Blazer Hartwig. You are fond of American iron, aren't you?

Do you by chance have a diagram of the coolant flow @Hartwig , I can't seem to find a good picture showing the coolant path.
This is the heater I have installed:

You've got that right :-)

Our plan was to emigrate to the US, because what's going on here in our "colorful" () country, is no longer acceptable. But it's pretty uncertain—especially given the current situation in the US—whether we'll be able to obtain a citizenship or at least a permanent residence permit.



You would get a good craftsman, so please put in a good word for me with Mr. Trump.

Got it dry fitted where I want it and now to drain the coolant and route the hoses. Wind is blowing 40kph and gusting 60kph easy so keeping crud out of my eyes is the challenge of the day

If you want, you can install a "splash guard" so that dirt isn't thrown against the heater.

@Hartwig

Any idea which way the flow would go on this pump?

I'm thinking the barb facing up is the outlet and the other barb is the intake. Pumps turn clockwise so that's my guess.

You know even living SoCal, this thing would be kind of nice for those cold (&#128514 mornings. Get the defrosted work even quicker.

In the link in post#33 are useful informations

Note: install the fuel supply pump as shown. Or fuel supply issues can occur

Got it installed for the most part. Just have to run the fuel line, put the intake and exhaust on, wire loom everything, build a shield to cover the heater/pump and wrap the hoses in fireproof insulation. Next weekend lol.

After I got the plumbing done I got the truck up to operating temp and no leaks found, also I was able to turn the pump on and I could hear the coolant flowing through the heater core so I'm assuming the truck needs to run a good bit to get any air out of the system yeah? That or the engine is so loud I'm not able to hear anything else when it's running.

Have a good evening fellas 🙂
