Evening

Picked up new radiator today for the 22RE, all went well with the removal and re install. Question on the extra brass service ports that are located on the bottom. I'm guessing its for an auxiliary hookup but will not use them on my setup. However need to seal them up as I'm sure they will blow out once it develops pressure. I'm sure its a novice question and did look around but didn't see anything. Probably searched using the wrong words.

Thanks in advance !

i'll upload some pics tonight

Those are used for the models with automatic transmission. The transmission lines are routed to the radiator to cool the transmission fluid.

My new radiator (Spectra) came with plugs for them. Make sure to tighten them. I did not and lost a lot of coolant. It hasn't leaked since then.

aaaand....

you do NOT have to plug those. as stated above those are for the AUTO tranny, but there is no communication between those 2 ports and the radiator fluid. replace the radiator on the 884runner (5 speed) and those ports are wide open.....and no prob.

You could use them to pre-heat your windshield washer fluid.
Really, that just occured to me.


But seriously, those fittings take more pressure from the auto-trans than the coolant puts on them, and they don't blow. If you're worried, just get some rubber caps and plug em.

Could ya use em as a oil heater/cooler? I like the window wash idea, there's gotta be a good use for em.

You guys are on the money...I used the word blow incorrectly above. What I meant to say was I was concerned with the rubber plugs that were on there. Anyway here are the pics, I just finished flushing and filling with fresh coolant. Truck runs fine, cool truck is a happy truck

Now that I'm thinking about it...could this be used to heat a liquid as long as one has a low volume pump to circulate? 92 toy said there is no communication between the two fluids...

So really this raditor has two seperate cooling coils? I never had one open except looking down the cap.

I'm thinking on a cold day I can make a gallon of coffee and keep it warm. Although would hate for that thin barrier of aluminum to fail..talk about a killer blend.

The pipe is too small to reliably flow engine oil: engine oil is somewhat more thick than ATF.

And even then, if the engine is running properly, there's no need to cool the oil. I could maybe see the benefit in warming the oil up faster though, you'd need a thermostat bypass. Not worth it.

Heat your wiper fluid, make espressos, whatever, just nothing other than those or trans fluid.

abecedarian

Yes and no. Two coils, yes. Cooling, no... sort of.
The coolant heats up faster than the auto-trans fluid so that helps warm up the auto-transmission. But then later, the ATF makes a lot of heat, so the trans fluid dumps the heat in to the radiator for the fan to get rid of.

Not aluminum- that's just the fins. The piping is copper.

But I suppose you could wire a pump to circulate your choice of liquid (I hear ethyl-alcohol is good) through the radiator then on to coils in your beverage of choice, to keep your beverage hot.

wait...

am I helping make a distillery here?

distillery ? that would be something. One thing is for sure, I'm sure the minds here can think of some interesting alternatives.

Final pic of the new radiator...
