If you can't find any leaks and you have it flow tested, you will know.
how can you tell if you need a radiator in a 99 cadillac northstar engine
If it's repairable, a reputable radiator shop will be a good resource. They can tell you if the radiator can be repaired or if it must be replaced.
A white surface is a good radiator of heat.
A radiator is defective if fluids are leaking out of the radiator or there is a leak of steam. Or, if thecore is blocked, the radiator will remain cold or just slightly warm in places.
An object that is a good radiator of electromagnetic waves is also a good source of energy (heat,light ...)
Usually a radiator is made of metal. Plastic can not take the pressure. A hole can be fixed by welding. A radiator shop can tell you for sure.
You need to get a tester at any auto supply store for 3-5 dollars. Dip in rad and it will tell you if fluid is good . If fluid is good, then there's no need to change it.
Replace the radiator with a new or good used one.
on the under side of the hood or along the top of the radiator it should tell you or you can call your local parts store and thay can tell you. good luck
Well, u would no that it's not if it starts burning and exploding! you would no if it isn't if it didn't burn up and explode! Hope I helped! :)
What I do is put half antifreeze and half water in to the radiator and keep putting more radiator fluid tell you see it in the neck of the radiator and put some radiator fluid in the coolant reservoir tank too.
