Is there a way to fix a radiator leak, in an emergency situation, temporarly until it can be changed or looked at by a trained professional? On a camping trip my truck overheated and now the "rad" leaks a little. Is there a product that will plug the leak... it's not a big one, I can last about one week without adding moe antifreeze/water. My truck is a 1990, GMC Sierra SLX, 350 engine, aluminum-plastic radiator

THX 4boltsChevy, but I know it's not the pump. The "rad" still holds fluid that circulates very well when the accelorator peddle is compressed. When the engine is hot, the leak or slight crack is on the driver side of the "rad". Only when there is enough pressure from hot liquids (to expand the hole area) is the leak kind of visible... I know it's near the bottom of the "rad" but I can't tell exactly where it is. Is there a quick fix that I can add to my "rad", along with more liquids, to plug the hole???

Its prolly not, but the pump. You been smelling AF for months,
all of a sudden overheat. Now you check it . If it was the rad
you' wouldn't have all this time. They go quick.
