Question about 1978 Chevrolet C1500

1 Answer

Radiator explosion, lose hose, not sure where it goes.

A hose came off my radiator I believe, as there was an explosion of radiator fluid from my 1977 C10 chevy pickup. There were no apparant holes or leakage viewable. Only one hose that connects to a pump, which I can only assume goes to the radiator. Problem is I do not know where exactly it goes. There is the drain cog, that is the only apparant place to hook a line, but not sure if that is suppose to have a hose connected there or not.

Should the 2 hoses from the radiator. Top hose from radiator to head, 2nd from radiator to block slides onto the thermostat housing. If you have a 2nd fan that could also have 2 hoses to cool the automatic system. When filling up the radiator - it goes through that into the bottom pipe - into the thermostat housing - around the engine block - into the heater - back through the engine block & out the top hose back to the same cycle. DON'T forget that when you have lost water as you have keep the radiator cap off & let the radiator burp until all the bubbles come out. Sometime you may need to help it by squeezing the hoses, being careful when the engine gets hotter. Good luck

What cause lower radiator hose to collapse after cool down

Hi Larry:
Good observation. Not too many people would spot that.
When the engine is hot, the coolant is hot and expands. At the filler cap for the radiator, there will be a hose that goes to the overflow tank. As the coolant fluid expands, it flows through thie tube into the overflow tank.
When the engine is turned off, as it cools, the volume of coolant in the engine and radiator contracts, and is supposed to suck fluid back from the overflow tank.
I'm suspicious that something is preventing this from happening so the vacuum in the engine coolant system is collapsing the hose.
- Check the radiator cap. Make sure it is functioning correctly. Make sure that it is correctly installed and screwed all the way on.
- Check the coolant overflow hose. Make sure it is not plugged.
Odds are that you will find the problem quite quickly.

Radiator removal instructions

Remove the fan and shroud. Put a large (!) drain pan under the radiator and drain it - if you're lucky it'll have a drain petcock near the lower radiator hose. Unscrew the radiator hose clamps and disconnect the upper & lower radiator hoses. Disconnect the transmission cooler lines if they also go into the radiator (some do, some don't)... you'll want a second, small, drain pan to catch the transmission fluid.

Now unbolt the clamps that hold the radiator to the radiator support plate (across the front of the car). Lift the radiator straight up, being sure not to lose the rubber mount isolator pads. Remove it from the car.

Replacement is pretty much the reverse of disassembly - put the new radiator in place CAREFULLY so you don't damage it, put the mounting clamps back on, reconnect the transmission cooler lines and radiator hoses, check the petcock (if the new radiator has one) to be sure it's closed snugly, reattach the fan and shroud.

Now refill the cooling sytem with all NEW antifreeze/coolant and water mix, about 50/50. DO NOT reuse the old antifreeze. Take close note of exactly what brand and type of antifreeze you used, and never NEVER mix any other brand/type of antifreeze with it, only exactly the same brand/type.

After refilling the cooling system, start the car & check the transmission fluid. Top off if necessary.

Leaking radiator... on drivers side, facing the engine, in the bottom corner, there is a place that appears to have had a also appears to be where the fluid is coming out at... difficult to see...

It's not the drain plug, is it? I don't think there would be a coolant hose there. Sometimes a drain plug will have a short hose to direct the drain downward.
There may also be two lines to the radiator from the transaxle-they are cooling lines to a separate reservoir inside the radiator, to cool the transmission fluid. Examine the fluid and see if it is coolant or transmission fluid. Your radiator may have to come off to stop the leak if it is not a drain plug that just needs a new o-ring seal or needs tightening.

Loses tranny fluid with no sign of leak. Does my 2000 subaru outback have a modulator diaphram on the vaccum system and how do I fix that? Does the vaccum line need to be replaced if this in an issue?

Your transmission is electronically controlled and should not have any lines or hoses coming off of it except for the cooler lines and the vent. I would double check to make sure your trans cooler isn't leaking into your radiator. If you can't see anything when removing the radiator cap then you might have to remove the lower radiator hose to see what the fluid looks like.
I hope this info helps!~subyguru~

I am assuming that the resrvoir under the hood near the passenger's side is for coolant?

Yes it is.If you need to know for sure follow the small overflow hose underneath the radiator cap it runs from the radiator to the coolant tank.

Yes you can but make sure the radiator is also full. The radiator uses suction to pull fluid back into it from the overflow reservoir. If there is a leak there may not be enough suction available to **** fluid back into the radiator as the engine cools.

2004 Ford Rager over heat lifgt goes on loses

There is a leak somewhere in the cooling system if the radiator is dripping fluid. A new thermosat won't solve this problem, as the system is already leaking.

Replace the radiator if it is leaking.

Look for leaks elsewhere, as well, and replace parts that leak.

Make sure the fan turns on when it gets hot, or when a/c is turned on.

Hope this helps.
