A hair to the left or right of the 1 in 210. Mine runs between the 2 and the 1.
Violence may not be the answer but it sure cuts down on the stupid questions

just a bit off 210. I guess thats 190, which is when the thermostat opens.
97 SE still running strong.

i have the aev highilne kit on mine, when it was leaking (once the t-stat opened) i would be on the highway and i thought that i blew a radiator hose. couldnt see a damn thing. pretty bad when you mother (passenger, which she knows a quite bit about cars) asks, "did you loose a hose?"

I would not wait a month. If it opens up more you are going to have a mess and possibly more problems and be stranded.

I wouldn't wait to install the new rad if you have the funds now if i were you. Speaking from recent experience, unless your going to check the levels in your rad every time you drive and top it off. (i did for over 4 months, it was getting expensive to buy coolant until i could do the swap) It only took one time on the freeway and my leaking rad got worse and ended up getting so low it destroyed my water pump and almost caused me to overheat. While your at it i would also consider doing your water pump and thermostat that way you can do the job once and not have to go back in say 4,000 miles to do your waterpump, its not expensive and its honestly a very easy job that can be done with basic hand tools.
