I installed my Cobra H/E the other day and relitively all is well. I am having one small problem and would like your thoughts on this.

After installing the H/E and plumbing in the hoses I removed the bleeder bolt from the top of the Stock H/E. Now when I was removing it it seemed to take a lot of effort to remove but it did com undone. So apon inspecting the plug I noticed that the threads looked a bit stripped from when it was installed from the factory. So I proceded to clean the threads so I could re install it. Now it took some effort toget it to screw back in but I got it to screw in all the way to the existing mark from the factory but I am still seeing some coolant seeping ever so slightly when the car reaches operating temp. I tried to tighten it a little more thinking that maybe I did not tighten it enough but it still weeps.

So for all you guys that have done the H/E mod, did any of you remove this plug and if so did you have any problems getting it out? Also When you reinstalled it what type of sealer did you use and did you have any problems putting it back in.

cheers and thanks for your input

 

Remove the screw and apply some thread tape(plumbing store ).
But I recommend the liquid version of thread sealer (loctite makes a good product) And reinstall it.

With a little more work you could drill and top it one size bigger and by a plug to match.

 

I first noticed how weak the lil bolt was and used a small cresent to take it out, then i applied plumbers paste. otherwise known as pipe dope. Looks like white thick toothpaste. works very well. tighten with cresent again and works like a champ.

 

I'm just afraid to take it back out but I guess I will have to. I new I should have put some sealant on there, my bad and now it may cost me. I will go see if I can buy a new plug and some sealant.

Thanks

 

yup that should work.

I found when doing mine that the bleeder screw didnt help me jack **** anyway.

just run the pump with the cap off, and keep filling, and check it after every drive for a few days and top up as necessary.

 

if the threads are messed up i would reccomend using the same plug... you may have created a new thread pitch by using it again there will be less chance of stripping it... just use lots of pipe dope (thread sealer liquid) and remember dont tighten! thats not what seals it its the pipe dope taking up the gap in the threads that will seal it... and worse case is you have to drill and tap

 

Yeh. The bleeder didn't do jack. OK, I will get some plumbers past and fix it when I have the chance. It is only weeping a bit.

Thanks
