how to test a radiator

OK im trying to save myself the $150 cost of a new radiator for my comet if i can. Is there any way to flush my radiator? Its got some light surface rust in it, so how can i flush it and test it??

 

I like pulling mine before I flush them. I cap the end for the lower hose and use a common flush from Carquest. Then I shove a high pressure water hose down it's throat and clear it out until I'm satisfied.

It's worked wonders for me. I've gotten ALL sorts of shit out including a mouse and it's nest.

If I wanna check the solidity of the core tho? I'll stick the nozzle to my pressure washer down it and give it a go. If the cores crap she'll piss all over the place.

 

haha ok sounds like a good idea to me. its pulled already too, thanks man.

 

***checks for dick***

Not a problem DUDE.

 

Here's a low buck trick I've used:
Get a bicycle tube and slice it in half so you have two open ends that you can stretch over the inlet and outlet necks. Tighten a hose clamp around them, add water and tighten the radiator cap. Take a hand pump for a bicycle and pump a few pounds of pressure into the valve stem and look for leaks.
I would also add that $150.00 for a new radiator is probably money well spent in the long run...

 

I flushed one once. I like to never got it back from the depths, and the snake made holes in it.

Brandy's method works real well.

 

fill it with vinegar

 

At $150 for a new one, or even a RECORED one, I'd buy two. I just laid $354 and some change down on recoring just my one. I could had bought an aluminum for $100 less, but then I'd have to hassle with getting it to fit......and I've got more money then I've got time.

 

cap hole, spray soapy water all over the radiator, blow air into the open hole,look for bubbles, or just buy a new one like that "guy" brandy said.lol

 

I have "testicles", they just happen to be 2 foot above where they should be and I seem to have a serious case of elephantitus.

 

A radiator shop should be able to rod-out yours for about 40 bucks. They will tell you beforehand if it is good or bad..

If they are a reputable shop.

 

What he said. A good experianced shop can pretty much tell by looking at it whether it's worth spending money on it.
