Pinhole in the top of the radiator. what can i use to repair it.the pinhole is directly opposite the top hose. so, i could pull off the hose to get to the pinhole, what can i use.

Don't waste your money on unnecessary sources and unwanted repairs. Get this manual online at www.reliable-store.com and get complete guide on whether to repair or not, service it, and how to repair etc

U have a pinhole somewhere probably in hose or in the radiator

twist open the drain plug on the bottom of the radiator to drain the fluid second you take the top and bottom radiator hose off third you you aren't screw the transmission lines leading to the side of the radiator forth you remove the boats going across the top of the unit and on the side then pull radiator out of spot replace opposite directions

You need the overflow tank functional, use plastic
repair for the tank

drain remove lower hose trans lines bolts that hold fan shrould on top same thing hoses bolts move shrould back pull up and out its 6 to 8 bolts all together that hold every thing in place.

In a properly working system, the coolant expands as the coolant temp rises. The excess coolant flows into the overflow container by the hose that runs from the bottom of the overflow to the top of the radiator, under the radiator cap. When the coolant begins to cool down, it contracts,drawing fluid back into the radiator from the overflow. The water pump has a "weep" hole located near the bottom of the pump housing that will leak coolant if the pump is going bad. In some engines, the 3.0, the water pump is located under the camshaft timing belt cover, and is a BEAR to deal with. However, the coolant should be pulled into the radiator when the engine cools, so check that the hose from the top of the radiator is attached to the bottom of the overflow and that it is not blocked or pinched. Have the system pressure tested to verify that it has no leaks. Hope this helps. Dano

just took 1 out of 92 grand caravan...unplug fan and remove the fan shroud from radiator ..then remove upper and lower hoses and cooling shroud for ac and remove top plate above radiator and pull radiator straight up and out. replace opposite way.

Start by removing the shroud over the radiator area. There should be little plastic screws in it holding it on. Then drain the coolant from the old radiator. there should be a drain on the lower passenger side of the radiator facing the rear. looks like a white nut, turn that until fluid runs out. Make sure you have something available to catch the coolant. I used a small rubber hose attached to the end of drain to direct it to container. After all fluid has drained, disconnect the overflow hose running to the plastic bottle on right of radiator. Remove the 3 bolts holding the bottle in place, and remove. You will not have to remove fan and shroud from vehicle if you just remove the four bolts holding the blade itself to the pulley you can then slide them back far enough away from radiator to get it out. That will make things much easier. there are two other hoses that attach to the radiator 1 on upper passanger side and 1 on lower driver side, remove those. Then remove the two transmission cooling lines from the radiator and plug the ends to prevent dirt getting in. Once all hoses and lines are detached from radiator remove the two mounting bolts at top of the radiator where it attaches. Those are the only bolts holding it in. it rest inside grooves at bottom so you just pull up the radiator and you have it removed. Installation is the opposite of removal. Try to get your plastic (degas) bottle as clean as you can if your reusing . If radiator will not drain through plug for whatever reason, removing the lower driver side hose will drain very quickly but be ready for a rush of coolant. I hope this helps you out.

its very simple. just remove the top shroud. then there should be two bolts on top holding the radiator secure, remove any fans, pull back the hoses, there might be some ol lines to the radiator (pull those to) everything goes back the same way

its a drain plug. You can just pull off the bottom radiator hose if you want this will drain the radiator pretty good as well. Let a garden hose run in the radiator to the water runs out bottom clear put hose back on and add the antifreeze top off with water. Bleed the system of air.
