losing coolant

I have a 2000 Tacoma 3.4 and I did the head gasket job and I still losing coolant
No puddles or in the engine
Somebody told me it could be the oil cooler but I don’t wanna keep throwing more money in it
Anybody with the same problem

 

Is your oil milky looking? If you run it without the radiator cap, does it look like it's boiling in the radiator? Any white smoke?

 

Nop
Like I said no puddles or milky oil or overheating

 

How much coolant have you lost? In can only go so many places.

 

Any white powder along the top of the radiator?

Any chalkyness around the right front (facing the engine)?

Any water in the passenger floorboard?

What temperature is the truck running at?

 

Just a little bit every day but like I said no puddles

 

@OneWheelPeel just gave you a list of suggestions; none of them apply to you?

I replaced my radiator because it had a leak -



Here you can see the long crack in the plastic -

 

Yeah like I said no puddles
That’s why I went go ahead and do a head job on it and the machine shop checked the heads for cracks and they came out good but I still have the same problem
Losing coolant and I don’t know where is going

 

We got it, no puddles.

But I'm referring to maybe any dried coolant anywhere on top? It could be seeping out and burning off hence why you won't see any puddles. You'll be left with a residue though.

 

Ok
Yeah I don’t see anything
I thinking about throwing one of those engines that come fro japan
The only problem is that I spent like $700 bucks already in this existing engine

 

Can always throw a dye in the coolant, run it for a few days and look for obvious staining. Taletail for leaks.

 

as mentioned above... it could be anywhere. In my experience mysterious leaks are at either the thermostat bypass tube under the lower intake, core plugs on the back of the block or seepage and consumption at the upper intake to head. Did you do the work?

 

Did you have the heads magnafluxed and machined? You could have a cracked head and be burning the coolant off.

 

What's the condition of the cap? The seal on mine was bad (old) and I was losing coolant but no noticeable staining. Topped it up with distilled water, new cap and problem solved.

 

You could also check your water pump. It could be leaking a little bit and evaporate from the heat so you would not notice any puddles. Just a thought.

 

The pressurized cap raises the boiling point of the coolant. If the cap is not sealing correctly your coolant will boil out of the top of the radiator and you'll never see a puddle. I would change the cap and see if that solves the issue

 

Do you smell coolant at all?

 

This is what I was thinking. Dont remember the member, but he had a slow leak from his weep hole. Wasnt enough to create a "puddle" but once he pulled the timing cover and looked, it was obvious.

 

Where do you think Bigfoot lives?
