Question

How do I get a hold of the clamp on the bottom of the top hose?

Community Answer

If you can see the nut, you need a very long screw driver or a socket with long extensions. If not, you need to wiggle your hand through the best you can to get at it.

Question

The hose that connects the radiator to the engine is loose and is leaking. How do I safely reattach it?

Community Answer

Make sure the engine is cool and then tighten the clamps. If that doesn't help, replace the hose and clamps.

Question

They forgot to put the clamp on the coolant hose and the hose came off, what kind of damage did it cause?

Community Answer

If the car got very hot you could have gotten a blown head gasket or lost all the coolant. If the clamp is back on and the car is not overheating, you're in good shape. If it is overheating, bring it back to the person who forgot the clamp and have them fix it.

Question

Do I need to change the hose to the water pump?

Community Answer

Change hoses as needed. I recommend you to check all hoses, since you will be draining all the coolant from the vehicle. You might as well address all the issues now.

Question

Can I use lubricant on the inside of a tight fitting hose to help it slide over the nipple and stub-out?

Community Answer

Yes. I would recommend using a little undiluted antifreeze as a lubricant.
