I had my throttle body gasket replaced about a year ago. I have been losing coolant so I dye tested it yesterday. I think the throttle body is the culprit again! Any suggestions for replacing it. The pictures show the coolant pretty good with the dye in it. Is it the gasket or something more sinister? Thanks. I will get out to work on it as soon as it warms up here in south Louisiana...its been in the 40's. I know some of you are laughing, but for here that is cold. haha.

Bypass that horrible piece of garbage. I did mine 2 days ago. The kit from the dealership is $25 bucks, you can't get just the gasket. I bypassed mine for under $2.00 and I will not have to worry about it leaking again and it took 15 minutes. Hell, Disco Mike bypassed his so I am confident this is a good fix.

 

Awesome, thanks for the info...bypass it is.

 

Do not by pass it.
Here is the gasket, it's $3.
Fix it correctly.

Use some fine sandpaper on the throttle body to clean up any corrosion and then use that purple permatex hi tack gasket sealant on the gasket both sides.

 

Okay...gasket it is. haha, Iam easily persuaded.

 

Wow! For $3 a pop you might as well stock up because you will be performing that job over and over and over and over and over............

 

That is a great idea.
For that price you could replace that gasket every time you did a coolant flush, which LR recommends every 36 months or 45,000 miles, whichever is sooner for the DII.
OR, you could stop using DexCool and never have to replace it ever again because the DexCool will no longer be eating the gasket and causing it to leak.

 

If you're in below freezing temperatures I'd recommend not to bypass it, the purpose is to prevent ice buildup in the manifold.
