I recently bought a 93 with 140k miles on it. We had a cold spell here about a week ago and I noticed it seemed to leak some coolant in the driveway when I would start it up. I brought it in for an oil change the other day and the shop said they had to add almost two quarts of coolant but they couldn't find a leak anywhere. Anyone else experienced this or have any thoughts on what it could be? The radiator was replaced on this rig by the PO about 20k miles ago due to what I was told was a rock hitting it causing a leak. I'm starting the process of base lining it and want to make sure I fix any issues. They are currently running green coolant, Im going to go back to the Toyota red when I do a flush possibly today. Thanks.

It appeared to be leaking near the front around the radiator. I haven't seen it do it since it warmed up.

Think I should change it out or just monitor it?
Most likely the radiator has a leak. Check the tank to core seam on the bottom. Red is a waste of money, IMHO.

Check the hose and hose clamps on your upper radiator hose. I had some non factory clamps that worked themselves loose over time and on a particularly cold morning I was getting seeping. Tightened them down and it has been good since. Not saying this is your situation, but it's one thing (of many) to look into.

After reading about changing the water pump I'll check all the hoses and clamps first. The wife wasn't crazy about me buying this and she drives it into the Mtns when there's snow. If something broke and she got stuck up there I'd never hear the end of it.
So you won't hear the end of it, I suggest you buy a new EFI relay and throw it in the glove box, and show her exactly where it goes in the relay panel.

Anyone driving a 20 year old vehicle should have a UV dye kit to easily and definitively find fluid leaks when they are noticed. They include the dye, a UV light and yellow glasses to help see the luminescence. Get the kit that has a light on a long flexy wand for tight spots. Would take you 5 minutes to know precisely, with zero doubt, and I find that saves time, money and the aggravation of replacing the wrong item.
Here is a somewhat common spot for leaks

Green coolant is somewhat fluorescent, and its emission wavelength in the same general color space than the common dye used for A/C... just sayin'
Somehow, that's a long-winded argument for using Toyota Red, right?
