heater hose connection leak
Noticed a little puddle of coolant on the top of my timing chain cover coming from the 90 degree fitting at the intake manifold (it's not leaking from the hose). Of course I can't tighten it because it hits the fitting and the short hose that goes to the water pump. Is there any way I can stop the leak without taking the water pump or manifold off. I thought about Stop Leak ??? or loosening the 90 degree fitting (can only go about 1/4 turn) and spraying 'something' on the threads and re-tightening it???.
Anyone know any tricks they are willing to share

Re: heater hose connection leak
Can you cut it off somehow and take it out and replace it w/shorter elbow?

The snout that the heater hose goes on would have to be 3/8" or less to clear the water pump hose.

Re: heater hose connection leak
I backed off the heater hose fitting a little more than a 1/4 turn, the 90 degree fitting snout that the heater hose connects to, the left (90 degree) fitting, hit the 2" (+ or -) hose that connects the water pump to the intake manifold. I measured the distance between the heater hose fitting and the short hose and it was 3/8" between. So if I could cut and remove the left fitting I would need a 90 degree fitting with a 3/8" or less 'snout' in order to clear the short hose that connects the water pump to the intake manifold to screw it into the intake manifold, wheww.

Re: heater hose connection leak
If you look in the chassis tech on my frontend swap on the last page and the last pic are you talking about the little hose in between the pump and intake. I shorten mine it is a pain to get on but with a couple of screw drivers it will go on only about 1\2 of the hose is on each nipple never has leaked so far. I was going to make it longer when i put engine back but forgot to pick up a new peace of hose.

Grease it up real good and it will slide right on.

The car is running and driveable, the problem is the 90 degree fitting (that attaches to the heater hose) that is to the left of the short hose that goes from the intake manifold to the water pump is leaking at the intake, and I don't want to remove the intake or water pump to fix it, if possible.

Re: heater hose connection leak
I made a new one outta 1" square aluminun bar. Intersect drilled and tapped for 3/8" NPT. Used a close nipple from manifold to block, and new hose nipple from block to hose. Had just enough room to spin on the new block. It dont look too bad with a scotch brite finish on it........

I backed the 90 degree fitting off till it hit the short hose, cleaned the threads at the intake the best I could and put some permatex red thread locker on the 1/2 of thread . Then tightened it as far as I could leaving just enough room under the top hose to the radiator to get my heater hose back on If that doesn't stop it then I'll try to cut it like Rick said and make a fitting like you did. Or maybe take the water pump off
Thanks guys .

Re: heater hose connection leak
Terry,I just went through this when I switched engines from a BB to a Windsor in a 71 mach. I have some different size elbowed fittings you are more than welcome to try.

This may really test the strength of the permatex red. If it works maybe I can 'give' some useful info on the Forum for a change
haha.
Thanks Rick

Re: heater hose connection leak
The permatex red seems to be holding, not much run time though.
