I found this out years ago and this is what worked for me. After putting new tstats, rad caps, clamps, etc.


The coolant cant be at the full mark on the tank. Make sure its a little above add (about half way over).

And no more spray.

If you have the stant cap. Bend the taps inward with needle nose plyers. It allows the cap to close tighter and seal better.

I had the same problem for awhile and did all the recommended upgrades and still the same problem. I finally replaced the t-stat housing for a billet piece which I got from a forum member and problem has been solved. If you look at the flange on the stock piece it is very thin.

Blah blah blah... I had the same issues and did everything that everyone on here has recommended. In the end, the one that worked for me is to keep the coolant level in the overflow tank low just like Crookster said earlier. I can't explain why this worked for me but there are several if not dozens of posts on this. I have the level right at or just above the low mark. Never had any coolant spray since then.

It doesn't make any sense what-so-ever to say there is too much coolant in the system, but I'm telling you for whatever reason my spray stopped when I did that.

I got a new cap. I bent the tabs. I flushed the system (best I could). I removed the tank and painted it and cleaned and made sure the hose was good to go. I put on a one piece radiator hose and a new t-stat. I did all these things, and the last I did was to keep the level low in the tank. I read it a number of places but didn't think that would have any effect.

Thanks to SUPRAMAN93.

I've been battling the spray for about two months now. Replaced the OEM water neck with the billet one with a felpro gasket and the spray has stopped :)
