 Posted: Wed Mar 04, 2015 8:37 pm Post subject: Pressure tested cooling system tonight - question |
 |
|
| So I pressure tested the cooling system tonight. Pumped it up to 14-15 psi. Good news - I didn't see the head stud leak I thought I might have. Bad news, I did have drips from two hoses. One I could tighten up and the drip went away. The other is the elbow tube that goes into the bottom of the thermostat housing. The hose clamp bolt is -impossible- to get to from the top or bottom due to the way it was installed. I hate to pull the whole assembly out to get to it right now - so here's the question - I have limited experience with this type of thing - how safe is it to leave it for now? Would this type of leak generally be a catastrophic and sudden type of failure or a just watch it closely and it will get progressively worse type of failure? |

It's not impossible. You need the right tools and a left handed wife.

well it kind of depends, if the leak if from a torn hose, or cracked plastic housing, then catastrophic failure is possible. if the hose clamp is just a little loose you still could have the hose blow off, specially if the parts get extra hot , say on a hot day under hard driving.

Always a good idea to post what year/engine/transmission you own. Someone here may say "Oh, yeah - lower the engine an inch on its mounts and its a straight shot with a nut driver from the front." Otherwise, you may get nothing. A pic would help also. I've always found a way even if it meant cracking a wrench in half and using one half only.
