If aluminum radiator you may run into problems repairing. If copper. No problem/ Those radiators Aluminum aren't as expensive as the copper. Good luck, Ned

Testimonial: " I found 4 leaks in 4 different tubes, on a two row radiator, I cut the tube at the leak, then smashed and twisted the tube up. Then solder the ends."

    Solder ing is the copper repair. It is recommend that a radiator shop make the repair. I've chased leaks all over a radiator that I created for lack of "the touch" plus if the leak is from the tubing worn thin they will detect it. Good Luck, Ned

    I've always used Jurupa radiator on Jurupa rd.

    That is probably all they would have done. Just be alert for a blow out if there are other weak tubes.. good going

Coolant temp 218 and smoking when I shut he car off


Engine is overheating. When the engine is cool, check coolant lever (remove radiator cap to check. If o.k. first repalce htermosatat and radiaotr cap. If problem continues, remove fan assy when engine is warm and feel the middle area of radiator (fins). If cold and the rest of the radiator is hot, you have a clogged radiator. Replalce it with a new one.

Also, there are two plastic "elbows" that couile coolant to the heater core (eventuallty). They are located in the area beneath the alternator. They are prone to leaking or outright breaking. Good preventive maintenace require them tobe be replaced The fix is to replace both of them with aluminum elbows, commonly available now in parts stores for that purpose. Don't replace them with new plastic ones! They will break just by looking at them!

Emergency weld for all metal radiators. Those mechanically inclined
This is a procedure for emergency repair only when you can’t get to a shop and you need to fix a leak in a radiator. First you will need three things one d size battery 12 feet of #12 copper wire or 2 strands 6 feet long. And a pair of needle nosed pliers and some mechanical solder flux core 60/10 resin. Find the fin in the radiator that is leaking with the needle nose pliers remove the cooling fns, these are thin the actual water cores are thinker, once you find the leak with the needle nose pliers remove 1 to 2 inches of the cooling fins from the radiator (Ones Not holding water) give them a twist and pull out the thin fins. Next drain the radiator below the leak snip the cooling fin right where the leak is and with the needle nose pliers bend back the cooling fin by a ¼ inch on both sides. Clean with sand paper or dry as best as you can. Take the D size battery and remove the center carbon core by removing the top, this is toxic so keep it off your hands. Next wrap a wire around the positive post and wrap the other end of the wire around the d battery core. Now ground the radiator with the other cable to the negative side and place it near the crimped side using the d battery core on the area that is bent and put solder onto the bent fin, do this on both sides. Be sure the solder is silver before removing the d core from fin; also hold the core with the needle nose pliers so that you don’t get burned. Let cool add coolant heat the motor up to see if it leaks if it don’t your good to go, be sure to refill the radiator back up with fluid, anything will do to get you home, except motor oil brake fluid or transmission fluid. Beer wine water and antifreeze are the best. This will get you home till you get it fixed; this is for those that have that luck when you need it most it breaks.

The evaporator is that finned radiator under the dash The tx valve is plumbed into the pipe going into the evaporator and has a fixed hole. The tx valve is controlled by the thermostat that is located in the fins externally on a small metal tube. If you have temp problems replace the thermostat first

Adjust radiator cooling fan 2003 kia optima


There is no adjustment on the cooling fan. If the car overheats, there are only a few things it could be. First, with the engine off and cool, check if the radiator is full of coolant and it looks clean.

The most likely cause of overheating is a stuck thermostat. You will need to drain the coolant and replace the thermostat. You can locate it easily by following the top radiator hose to the housing on the engine. The thermostat is under this housing.

You could also have some kind of blockage on your radiator. If there is a lot of dirt in the fins, air cannot circulate and remove the heat. Use some compressed air to blow the fins clean.

I have a 2001 nissian maxima that runs hot while driving but is normal while just sitting idol. We replaced both thermostats and we checked the hose after driving and only one side was hot n the other was...


When I have a car that runs hot while moving, cools down sitting I immediately check
the radiator fins for clogging with debris, hair, dirt, bugs.
This is a sort of easy fix and you do not have to buy parts.
Drain the radiator and save the fluid.
Remove the radiator and hold it up to the light.
If you cannot see through it easily then start washing the outside and the fins.
I use water pressure, air, and a shop vac to clean the cooling fins.
Taking the radiator to a shop where they hot tank it accomplishes the same thing.
There is a product for cleaning the radiator fins, but I have never needed it.
The good news is a new radiator is probably not needed.
This assumes that you have never used a stop leak product inside and have
only used anti-freeze/water.
You might be able to clean the radiator fins without removing it , try water and soap.

My low level coolant light keeps coming in on my 1998 chevy monte carlo. level is good. any suggestions?


evidently there is a leak. I would check the hoses, thermostat housing, drain **** for radiator and the fins on the radiator for fluid leaking. The water pump housing and at the weep hole is another place to check. If it is leaking from the fins they do sell a stop leak. Hope this helps tim

White smoke is coming from my Radiator and there is a leak. I checked the main hose and it was fine. Are there other hoses and if not where should I check next


Yes there is. You have hoses that run to your heater core, they go right into the firewall on pass. side. There should be a hose on the bottom of radiator also. There also is a hose that goes to your water pump. Check the fins on the radiator. these go horizontal in between the mesh. Its hard to explain. If you find a small hole in the fins you can sqeeze it together with plyers. Thats a quick fix untill you get a radiator.

I changed the thermostat, water pump but it still overheats


The mechanic should check on the radiator and the radiator fan .Also check the cooling fins of the radiator if the cooling fins are worn out then replace them. You should also check if there is a leak in the radiator and then repair the radiator .The radiator fan ,check it also if the the pulley of the fan is working and if not then replace it or repair it.And the engine oil should be check if the engine oil is dirty or diluted then change oil because of sometimes dirty or diluted oil can cause engine over heat.
