The thread stripped on my 996 1999 plastic radiator. It's just a small leak but it's every day and worse when it's hot.

Is there a tape or work around to help this seal better?

Plumbers tape goes to 500 degrees, I wonder if that's enough?

One of these, cracked head from overheating, will cost you way more then a new tank. Get it fixed.

Dude did you just say that? I know of a couple people here that would take offense.

Get a new reservoir. Change it out man. I am all for the 'easy way' but in this case, THAT is the easy way.

I do. BUT if you go this route and get plumbers tape from Home Depot, make sure to get some latex paint from their to touch up your interior too.

Jesus anyone here not miserable in life lol?
Go for a walk or something.

It's a small leak because a plastic thread is a little stripped, if you can fix it with a little tape that's a little better than a grand.

Not rocket science here, just trying to stop a small leak in plastic threads. I guess I chose the wrong place to get help.

That made me laugh.

The leak is probably from the rubber seal, not necessarily the threads. Try a new cap first if yours is a 99 and has the original cap.

we're a little grumpy in the mornings... The cooling system should be repaired properly. Considering you own a 99 you have to expect to throw money at it from time to time no? Maybe you could find a used replacement part to keep the cost down?

Maybe not obvious but folks here ARE trying to help. The reason is although it's a small leak, if not repaired properly, there could be chain reactions that could lead to engine damage. Leak->no pressure->coolant boils->local super heated spots->engine damage. To replace the tank should not cost $1k (more like a few hundreds). Also, these tanks regularly leak as they age so you cannot avoid replacing it at some point in time anyway.

This is Rennlist where people try to make a rocket science out of everything.

A small leak in a non-pressurized application "might" be ok but pressurized applications can lead to big leaks. This is a $20k+ engine in case you didn't know. 2min(for a cap) or 1-2 hours for tank replacement(depending on if mk1 or mk2) and a little bit of dough isn't so bad vs risking a high priced motor IMO. It's your car and if you are comfortable with the risks, have at it.

Be happy it's not a Boxster that need the tank replaced, its a real PIA and takes much longer
