S2 throttle body coolant leak

[Kings911]

Is there a quick easy fix for this?

unhook both hoses from the TB fittings and join them together with a barb connector/another piece of hose, bypass the TB entirely.

it's only there to prevent the TB from icing up which i don't think is much of a problem presently in NC?

Lol. No no problems there. What's the best way to cap the throttle body ports?

you can get little rubber caps in a variety of sizes are your local auto store.
though it'd be ok to just leave those open, to be honest.

it appears that your little fittings are leaking from where they join to the TB - you should be able to pull the fittings out with pliers. clean the hole in the TB and the fittings very well and you can re-install them with some epoxy (JBWeld) around the piece of the fitting that goes into the TB.

Great thanks!

I usually agree with you V2 but I think icing can occur in the S2 in NC easier than you think. I have seen carburetor and throttle body icing. Carb Heat is always applied when landing a piston powered aircraft, partial throttle operation is especially vulnerable to ice bridging, engine power slowly reduces and upon opening the throttle for more power the ice breaks loose and the engine coughs or quits from the slug of water and you land off field Apply carb heat before it's ices up so you don't get a slug of water when the carb heat melts the ice., always even if it's hot out. You loose a few horsepower with the hot Carb air but the fan keeps turning. I always though by-passing the TB heat to keep it cooler might add a few ponies though.

the ambient temperature has to get pretty low for it to ice. while i have also had carbs ice, they were exposed (dune buggy). this engine bay gets really warm, on average about 200 degrees F. once the engine is warm, i doubt it would be a problem.

that being said, what V2 has said will work, as long as it isn't too cold. i know a number of guys who have done it on a 968, which has the same setup. however, i would not do it in temperatures below about 45 degrees F.

Those black pieces are just press-fit into the aluminum throttle body. I had mine start to leak many years ago at a track day at Portland. Got that sickly sweet smell going down the back straight. I made a field repair with JB Weld in the paddock that lasted several years until I put in a 968 motor.
