Patient:
1990 GMC F/S Jimmy
350 CUI TBI w/ TH700R4 and NP241
130,000 miles
A while ago I noticed a slight leak right under the radiator cap. It was along the seam heading down the radiator outside the shroud. I got some JB Weld and drained the radiator. I let it cool off/dry off, and slathered the thing with JB Weld. I let it cure for about 24 hours, and called it fixed after a short test drive.
But recently it has started leaking worse, enough to drain a FULL (not to full line) but full too the top reserve tank in a week.
The JB Weld patch was soft and pliable, and pealed right off (where before it was like a rock).
The temperature rarely gets over the 1/4 mark on the OE gauge.
It also looks like there may be a little dribble from the water pump, bot enough to contribute to the puddle that will form under the truck, but enough to make me wonder if I should go buy a radiator and a water pump and get the job done???? As far as I can tell it isn't from the lower radiator hose which was recently replaced, it looks like the green/white trail heads up futher and out of sight....
