Spray outta radiator cap
 
Dunno if you guys w Hemi's and 180 tstats have this issue or not (some others do) but why do we get spray outta the rad cap??

Ok so I see 2 solutions. One new rad cap and/or hose clamp? It's easier to search threads w my comp opposed to my iPhone ;)

Over pressurising the system. Cap is set to 18psi anything more and it will relieve the pressure as it is the weakest link.

Mine does it to. I'd rather have that, than blow a line or worse.

The only solutions I can think of that will safely solve the problem is to tap the overflow in the rad neck to a larger fitting allowing it to move more fluid faster to the overflow tank therefor relieving the pressure.

hi ,

you should not have any leaks from the cap, if you do then you might have one or more problems,
1-the cap needs replacing
2-trapped air in the cooling system have it bled
3-a blown gasket :(
4- your cooling fan might be faulty

hope this helps

Thanks for this, good info to know!

It's not the cap its the connector hose next to it. It just gets too much presuure sometimes and it sprays out. Kind of a fail safe! :thumbsup:

I have the same issue when I drive the truck hard. Mine looks like it's coming from the rad cap, it sprays on the intake tube, etc
