Is This Normal??? Coolant Drip
-
Got the Pacemaker started after by-passing the heater core. Engine warmed up well, temp reading climbed to about 3/4 and held for a bit then dropped as the thermostat opened. And I let it idle for another 10 minutes.
After I shut it off and climbed out, I heard a "pssssh" and found coolant was dripping out of the over flow tube (into my safety bucket). So a few questions....
1) Is this normal as I work out any remaining trapped air that may get hot and expand?
2) Is my 7lb cap bad?
3) Does this indicate a deeper, more concerning issue?
Note: Before I did work on the car, it was overheating right away (lose head bolts, #1 & #3) and putting exhaust gases into the cooling system.
I also double checked the head bolt torque of a few and all were right on at 75lbs with the engine warm. -
Head gasket leaking is my guess. Is it foamy?
-
No foam just a short burst of coolant getting pushed out past the radiator cap.
-
Was the radiator topped off almost to the filler neck before you ran the engine? The top tank of radiator is not supposed to filled all the way to the neck, but about an inch above the core, to allow for expansion of the coolant as it heats up. a short burst of overflow would be normal on a hot motor that had the radiator overfilled.
-
From my experience, when an engine is turned off, the a combination of residual heat of the engine and no cooling from the radiator this does tend to increase the water temp for a short while. If the radiator was a bit fuller than it needed to be, the extra heat would expand the water and force some out. Usually when a radiator has found its natural level (maybe 1/2" or so below the top) there is no longer a problem - assuming all else is OK in the engine dept.
-
Over filled!!! We have a winner!!! I figured it to be trapped air bubbles because I was a quart shy of the 17 needed to fill the system and I had air in the upper hose.
So I will drain a pint from the bottom and see how that works.
Thanks!!!!!!!! Do I need to be concerned that the upper hose is very squishy as in not a lot of coolant into before I start the engine? -
The top hose sould be fine as long as the core is well covered. The hose will firm up as the pressure builds.
-
Yes, what Ken said is right. It sounds as though the radiator was over-filled. If you hook up an overflow tank (as on a newer car), then the excess would fill into the overflow tank and not out on the ground.
Squishy hose on the top is o.k., but a collapsed lower hose will result in too hot an engine/engine failure (can't cool efficiently). This will happen if: 1) There was no spring in the lower radiator hose to begin with, or 2) The spring has corroded and failed due to age, or lack of use. In other words, keep an eye on it, if you don't know the history of the hoses. -
All new Upper and Lower Hoses (including the steel section). The lowers are fairly stiff. I got them from one of the Hudson members that sells them.
Any body have pictures of a catch can/overflow tank add to a Hudson? I live in the Chesapeake Bay watershed and the fines are very heavy for even the littlest spills. -
I don't know if Hudson had an accessory over flow... But I do enjoy showing mine off. You could get a 'period' look with a big Mason jar.

Now that's funny right there.

Coolant recovery systems came along a bit after the Hudson era. Here's one I just got from PeP Boys, as my old one was looking pretty ratty. Note that one has to use a radiator cap intended for a recovery system, and I think the radiator neck also. Years ago when I had the radiator re-cored, the shop installed a Mustang neck on it for this reason.

Park, Did the wire cage come with the bottle? I like the look, even it is not 100% OEM - there something to be said for not leaving coolant drops all over the place.
-
Do you happen to remember a part number or anything that would help me order one?

Park, Thanks. GrimGreaser posted a link for a universal as well from Autozone. There is a PepBoys about 20 minutes from here so I will take a ride up there this week.

GrimGreaser, Thank you for the links. They help.
