hi jasso, I would recommend checking the water pump if you see no flow in the radiator. Make sure when you fill up the cooling system, that you fill it cold, and that the vent screw in the radiator is loose. fill system until fluid comes out the vent screw. tighten the screw, start the car and have someone run at 1500rpm and check for flow.also, make sure that you have your temp setting full hot and blower on middle speed so that you don't trap air in the heater core.

Your car battery is dead. Or the cable from the battery to the 12V terminal has a bad connection.

Having the battery disconnected for half an hour or so will drain the capacitors in the ECU. Connecting a battery at that point puts the computer into relearn mode automatically.

Where is the radiator drain plug on a 1993 Toyota Corolla?

Hi there,

For most Toyota radiators I know, the plug is in the center at the bottom of the radiator housing. If you cannot locate it, then simply remove the bottom radiator hose to drain the radiator. Keep in mind that you may need to replace the hose clamp if it has the one-use factory style clamp.

The drain plug is directly below your upper radiator hose at the bottom of the radiator. You can start by disconnecting the battery ground cable.

Hope this helps...

I have a 99 grand cherokee wj. The upper radiator hose keeps leaking where it contacts the radiator. I have changed the upper hose two times and also replaced the clamps 4 times and I am still having this...

I suspect either the radiator neck has hairline crack. You can try product like "Bars Leak". It's a coolant stop leak that is fantastic. Not only is it a stop leak product but it's also a waterpump lube.

RAdior is leaking badly what do I do? One of the hoses seems to be broken, and seems like a huge leak on the bottom??? Need help asap contact me at

  • Turn off the engine as soon as you suspect a leak, to prevent the engine from overheating.
  • 2 Determine which radiator hose is leaking and exactly where the leak is coming from by looking for wetness.
  • 3 Purchase 1 gallon of antifreeze and the correct replacement radiator hose from your local auto-parts store or dealer. (Radiator hoses are not interchangeable. They come in specific sizes and shapes for your particular car model.)
  • 4 Wait for the engine to cool down for at least 20 minutes, before beginning any work on the cooling system.
  • 5 Place a large pan or wide bucket on the ground under the hose to catch the coolant.
  • 6 Use a screwdriver to loosen the hose clamps at both ends of the hose you are replacing.
  • 7 Remove the radiator hose by twisting and pulling where it connects to the radiator and engine. If the hose won't budge, use a utility knife to cut it off the fittings.
  • 8 Remove the hose clamps from the old radiator hose and slide them onto the new hose.
  • 9 Put the new radiator hose on. Spray the inside of the hose ends with WD-40 if the hose is hard to get on. Tighten the hose clamps.
  • 10 Refill the radiator and the coolant reservoir with a 50-50 mixture of water and antifreeze.
  • 11 "Burp the cooling system" by running the engine with the radiator cap off until the engine warms up. Keep the engine running until both the upper and lower radiator hoses feel warm (this indicates that the thermostat is open and the coolant is flowing through the entire system). Burping the cooling system allows any air bubbles to escape. Add coolant to the radiator as needed.
  • 12 Look for leaks. Inspect around the hose clamps for dampness. Tighten the hose clamps if there is any wetness.
  • 13 Put the radiator cap back on.
  • 14 Check the coolant level after driving, to ensure there are no leaks

    Why does my chesk gages keep coming on and my car keep over heating?

    Check your coolant level in the coolant overflow bottle and in the radiator. If it is low, check the upper and lower coolant flow hoses and overflow hoses clamps for leaks. Check beneath the car for signs of coolant.

    I drive an oldsmobile aurora 98 and it keeps over heating. I have changed the radiator and the upper hose as well as the heating hose. now it seems like the lower hose is gone. it seems I keep changing...

    Based on the description, either the problem is on the water pump, the radiator fan or the hoses. If you have replaced the hoses or noticed that the hoses are not brittle and clamps are ok, then you can eliminate it as one of the source of the problem. Inspect the radiator fan if it turns on when you remove the thermostat. The thermostat looks like a small plug that has wires coming out of it and is connected to one of the radiator hoses. If it does not turn on it could be a problem on the relay or the fan itself. You may swap the AC fan relay with the radiator fan. If it still does not turn on then it is a bad fan. If it turns on then, have the relay replaced. Other than that your water pump for the radiator needs replacing. It may not be circulating water correctly.

    Oil Lead after new radiator and upper hose installation

    It sounds like one of the transmission cooling lines is leaking, where they attach to the radiator. There may be a rusty section that was 'bumped' while the hoses were being replaced, causing it to leak. If the section that is leaking is not the fitting at the radiator, but a bit away from it, you can cut the section of tubing at the leak, purchase and slip a section of rubber fuel line over the bad area, clamp both ends with small clamps. Make sure the tranny fluid is at the proper level, don't drive it low.

    Honda Odyssey Coolant System Prob.

    You may have air in the system. Run the car with the cap removed and the defrosters on allowing air to escape. Add antifreeze as needed to keep full while running. Fluid level will drop as thermostat opens.

    Start with the engine cold, and drain the coolant out of the radiator into a clean pan. loosen the clamps on either end of the upper radiator hose. twist the hose loose, then install the new hose along with new clamps. Fill up the radiator, start the engine for a few minutes, then shut down and check the coolant level again, and top off as needed. After the engine is up to temperature, check for leaks again, and recheck the coolant level the next time the car is cold again.

    I want to locate and change the thermostat.

    The thermostat is easy to find. Follow the upper radiator hose where it clamps onto the engine. The part that the hose clamps onto is a cover for the thermostat. Check the hose and make sure that it's in good shape; if there's soft spots, worn spots, or places where oil has gotten onto it and softened it, you will want to replace it as well. If so, you will want to drain about a half of a gallon out of the radiator first, then proceed. If you're keeping the hose, you can use a clamp and a couple of pieces of metal or wood to clamp the hose shut to keep it from leaking all over. After the hose is clamped, remove the clamp that holds the end of the hose to the engine, then remove the two bolts that hold the thermostat cover on. Remove the cover, clean the area up, making sure it's dry. Lift the thermostat out, and put the new one on exactly as the old one was. It is possible to put it on backwards, and that will cause huge problems. after the thermostat is in place. Taking the gasket that should come with the thermostat, if it's a flat gasket, put a bit of High-temp silicone sealant on it, spreading it thinly over the entire gasket. place the gasket in place, and bolt the cover in place. If it uses a rubber o-ring, replace as well, but silicone is not required. After the cover is bolted in place, reattach the hose, remove the clamp keeping it from leaking, and replace any antifreeze that you may have lost. Moniter for leaks for the next couple of weeks, check when you fill it with gas and check oil.
