96 drinks coolant

I am putting a half a gallon of coolant in ever two weeks. I see no leaks or puddles. I flushed the radiator and replaced the lower radiator hose a couple of months ago. Where is all this coolant going?:banghead: Thanks.

Could be you have a small enough leak that it just evaporates when it hits the hot engine, thus no pudddles. Or you could have a bad head gasket, and the coolant is being burned. The 3.0 V6 and 22RE are known for hg problems.

Man, it better not be a head gasket:uhoh: . Can I do a compression check to verify?

I had the same problem on a NEW engine replaced the radiator cap and it stopped. Didn't make sense but it fixed it. (no overflow or traces)

If you do a compression check make sure the coolant system is not pressurized.

I think he meant a compression check on the cooling system, since we're talking about a coolant leak.

He is talking about a compression check to test the head gasket.
How does the cooling system compress coolant? I know it pressurizes from heat expansion, not compression.

I meant to type a pressure check of the cooling system, to check for leaks.
It's an easy place to start. A cooling system pressure test is simpler than a compression test. But the easiest starting point is a new cap.

fourwd1 is right, the first place to start would be to do a "leak down" test.
The same tester is capable of testing the radiator cap also.
Good luck, and let us know.

I would do the following:

1)Place a napkin/paper towel over the tailpipe for a few minutes and smell it or see it for coolant residue
2)Perform an cooling system compression check
3)Perform an engine compression check
4)Perform a leak down test
5)Perform a fluid analysis test by buying a fluid analysis kit for $15-20 at any local Caterpillar dealer or any heavy duty repair shop that repairs bulldozers,cats,backhoes,big rigs & more.
6)There is a headgasket recall on most of the V6 engines used in Toyota trucks & 4-Runners,see below

The dealership will give a free rental car for a day or two and replace other routing maintenance parts and only bill you for those parts.The headgasket & it's labour is of course free.
