I'm going to be installing a water temp gauge sensor in the pass head under the #8 spark plug. When I take the original bolt out of the head should I have a pan ready to catch any coolant or will this be a relatively dry proceedure? I've never really worked on heads before so I figured I'd ask. Thanks!

 

You should always wear a raincoat.

 

 

yeah its going to be wet.. it will pour pretty hard out of it... just pull it the plug, and try and get the new sensor in there as fast as you can, do you dont drain the whole thing.

 

Jack up the passenger side of the car before you do it.

Seriously....



I'm not sure how much will come out, but it'll be quite a bit. I am not scared of having coolant run out all over the driveway, I've got a waterhose to wash it into the neighbors backyard with.

Taking the coil packs off the driver side will probably help you gain access BTW.

 

Do you mean the coils off the pass side? If so I'll have to look into that.

Thanks fellas

 

Yeshhhhhhhh teh driver side. No damn way you're getting that plug out with them on. This would be a good time to change the #8 plug too, unless you have LT's.

 

I just wanted to see what this thread was really about.

 

I figure odd titles brings quick attention to posts. It worked to bring you in didn't it?

 

I "nailed it from the top side" No raincoat required
Did it when I replaced my plugs, so coil pack and plugs were out of the way.
(headers left in place) The head plug is a internal allen wrench. Was a bit tight but with a regular allen wrench and a cheater bar on it came right out. Before you go for the install make sure to have the adapter for the sender.
Napa sells a kit, for this application. I myself just took a metric bolt and drilled-n-tapped it to the 1/8npt worked great, which also gave me much more room once the sender was installed, for the next plug change.

 

I already ordered an adapter from Summit. But thats actually a pretty good idea. I didnt even think about drilling and tapping my own out of a bolt. If I manage to break this one I'm taking your idea. Thanks.

 

You can always buy the steel adapter from
fittingsandadapters.com

 

Well, after two hours and a burnt backhand the sender is in! You guys gave great advice and the job went "easy" (for what its worth).

My only concern is the overall tightness of my adapter in the head. I've heard horror stories about the adapters breaking so I tightened it maybe two full turns after hand tight until the adapter became fairly firm. Hope this is enough because I ain't ripping out those coils again any time soon. At least not until my cuts all heal!

 

You can rest assured that anything out of the ordinary will attract this guy.
