LPG gases in cooling system ? - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

Has anybody ever experienced LPG gases leaking into the cooling system from the converter and creating heaps of bubbles?

Leaking from the convertor into the coiling system? It is possible but are you sure it's not a blown head gasket?

The block and heads have all been reconditioned and machined and I followed the normal instructions for torquing down the new Felfro head gaskets, so I hope it's not the gaskets.

By the way, I'm referring to an overheating problem in my son's 302W XY wagon, which I've outlined in the Windsor forum. I just thought I'd run the scenario by you guys.

Yep,

May be a cracked converter housing, easy enough to diagnose. Reroute coolant hoses to stop flow to converter, block one side and put another hose on other side filled with water, run and watch for your bubbles.

If you want some fun and don't value your health you could hold a match above radiator filler??

prob just water corrosion inside the converter is common

I'd try what blackxbhardtop has said.

Thanks guys, I'll try bypassing the water hoses to the converter, but how long can I run it before it starts icing up?

not long they ice up real quick there isnt much maet in the converters so corrsion may be the culprit the other thing is that gas has a oder that smells like bad eggs so if you remove the cap u should smell it

Hi I seem to have the same problem.
I have also had my heads done and replaced them, but still have the same problem.
Are the bubbles small and seem to be foaming. It's not oil I have checked that.
When you say re rout the water lines do you mean by pass the converter all together?

Thank you nev1956

Yeah just bypass the convertor,put a joiner in there for the time your testing it.

You will normally geta slight lpg smell as well when you release the cap
