    Did you replace the radiator or just fix it?

    WE REPLACED IT BUT IT LOOKS LIKE THE WATER IS FALLING FROM INFRONT OF THE MOTOR, IT OVER HEATED 3 DAYS AGO ON THE FREEWAY BUT THE PIN DIDNT GO PAST THE RED LINE BUT NOW WHEN WE ADD WATER IT JUST GOES STRAIGHT THRU AND FALLS FROM WHERE THE MOTOR IS. IS THERE MAYBE A PLUG OR SOMETHING THAT MAY HAVE BLOWN WHEN IT OVER HEATED.

The motor has plugs called freeze plugs, but these are located on the back of the motor. There isn't much that can cause water to leak on the front of the motor, although a cracked block or cylinder head cam cause this. There also may be a small hose along the front that split and is causing your leak. Visually inspect all of your hoses - especially you heater core hoses which come off of the water pump. I suspect one of those has a split or a hole, which would cause that leak where you state. If you cannot find the split or hole, ADD a bottle of green food coloring to a gallon of water and shake to mix well. Get an inspection mirror ( a small mirror on a flexible handle or with a flex joint at the mirror ) and a flashlight, and slowly have someone pour in the water as you look with the mirror and flashlight for the leak point. Look on the back side of the hoses, as well as along the water pump base and all hose connections. Also feel ( squeeze ) all of your hoses - if any one feels soft enough you can squeeze it shut, I would replace it - it could collapse and cause the engine to overheat.
I hope this helps!!

Well it depends where the bottom is. do you mean out of the engine? If so its probably the head gasket or a blow out plug, se if you can see exactly where it is coming from.

Overheating problem


Have you tried the thermostat. it might be stuck closed, causing the antifreeze not to circulate through the engine, in turn causing the engine to overheat. Go to YOUTUBE.com and type in "How to change a thermostat on a Chevy Blazer. There you'll get a video on where to look and how to change the thermostat.

If you have changed the water pump AND the radiator AND the thermostat and still have the problem then the hoses should be checked to be sure they are not collapsing, also make sure that the coolant is 50/50 water and coolant and the thermostat is installed right.

My 1989 dodge pickup only overheats going down highwa y just recently started i have replaced water pump,the thermostat and the radiator cap.i have even removed the thermostat and still building press


put the thermostat back in the right way . Check and replace the bottom radiator hose if it feels soft when cool. Old soft hoses will suck together at speed and slow down the coolant circulation. Have a flow test done on the radiator cores for partially blocked radiator.

I have replaced the engine coolant and my blazer still overheats


You just have to keep checking. Try a new thermostat. Also make sure you have a good radiator cap with a good seal, cause the seal pressurizes you coolant up to about 15 psi. Check if circulation is good: engine running at normal operating temp. (to make sure your thermostat is open), radiator cap off, squeeze top radiator hose closed(use gloves, if necessary) then release, and look in radiator to see if coolant surges when hose is released. Feel your bottom hose. It should be warm to hot, If it's cold, your radiator might need flushing. Check your water pump for signs of leakage (whitish deposits around bottom of pump.) If all checks out, you need to consider a compression test to see if your head gasket needs replacing. Good luck.

Overheating


Did I read that right and it has no thermostat?

Running it without a thermostat will cause it to overheat.

The problem is there is nothing to slow down / restrict the coolant and let the radiator do it's job.

A very common misconception on how cooling systems work..
