Another Coolant Loss Thread 1FZ/HG Replacement (pics)
I sort of hesitate to post this but after reading for hours and hours, finding many examples of my problem, I feel compelled to get more feed back on my issue.
1995 LC, 188K, 315's, just a DD, bought it from the original owner, (original HG) have been driving it for almost 4 yrs without any major problems until now. After driving home from work a month or so ago, I noticed a bubbling noise under the hood, the noise was coming from the radiator, I also noticed that the overflow tank was empty, so I filled it, started it and it sucked some into the radiator and drove on......a bit later I noticed the noise again and refilled the tank again, just thought that since its so hot here 100+, with the A/C on that maybe it was just low. Last night I get home and hear the same noise and refill.
I decided to check into things, no obvious leaks, some pink build up around some of the heater hoses in the back of motor, PHH changed at time of purchase and did a radiator flush with the red stuff. I read through Idahodoug's post (which scared the hell out of me), read through a post that talked about the "block test" or "HG test" with the blue liquid, went to Autozone and performed the test, no discolor, so according to that, no HG leak....I still have the kit so I'm going to do it again tonight just to make sure. I ordered a blackstone test kit. I'm going to get an app for my iphone that is similar to the scangauge II, so I can check the actual water temp to make sure its not boiling over during driving, but don't see any evidence of that.
There is a little (very little) smoke at start up but was hoping that was valve seal and didn't look like that typical white smoke that usually happens when burning antifreeze. I also read a post about an obscure leak on a hose but the water never hit the ground, I'm hoping this my situation, but I doubt it. I'm also going to try to look at the very back of the head, but I would have thought with this much coolant missing that it would more than likely make it to the ground. I'm at a loss....I'm sure a HG is in my future but not certain, having symptoms similar to Idahodoug's minus the boiling noise he had in the cat area, when he had a cracked head....
I'm not a stranger to blown HG's as I had a 90 4runner 3.0 v-6 that was a total nightmare, so I kinda know how they can act and what to expect.
Any other ideas?

Also, check the seals on the upper and lower radiator tanks, they start seeping on old radiators and can loose a lot of coolant before any hits the ground.
