Hi everyone,

My Jetta has a radiator leak in the top left. It's a 650$ repair and I'm short on money right now since I just moved. The leak is slow enough that I only need to top off my overflow bottle once a day.

What are my options for this issue besides paying for a proper repair? I realize it's unlikely anything can fix the problem, but I imagine it may buy me some time.

Has anyone had good results with Bar's Stopleak?

If I could find the hole could I try some epoxy over it or something?

What about just letting it go and topping it off every night?

Thanks!

Hit the junkyard and get a new radiator. I owned a mk4 VW. You can do the radiator swap yourself in one afternoon.

This is most likely either rot or failed plastic and it might quickly get worse.
The only cure is a new rad.
If you google around, you can certainly find one for less than six-fiddy and installation shouldn't be too difficult.
Check Rock Auto as a first resort.

Willing to DIY? Most radiators are not all that difficult to replace...my beautiful wife that doesn't know jack about cars (until she met me of course) was able to change the radiator on my truck after I had surgery. You can do it too. Shop amazon and you might be able to get away with a 50-150$ radiator, look at reviews.

How can a radiator job be $650?

An aftermarket radiator for a mk4 jetta is between $40-$100 depending on brand.

I would youtube it and DIY.

I replaced radiators in my toyota cars before its a one hour job even for non mechanics.

If new radiator and/or diy not feasable now, THE most recommended product on bitog for radiator leaks is Bars Leaks Tablets. AC Delco tabs the same.

For the cost of the repair, you can buy a new radiator. Check RockAuto.

That is correct, by the book. More or less the entire front of the car needs removed.

You do not need to disconnect the AC condenser though, you can just move it away.

Ridiculous. I've done the same job in 2 hours. Ac costs $150 to have charged.

Ok so:

$100 for aftermarket rad
$200 for 2hrs labor
$150 to have the AC charged.

Seems that $650 isn't too far off there, especially if the price includes an OE rad.

But why should a mechanic make any money?

Well, if you have a set of sockets and a few torx bits, this is a $60 repair.

This looks like a straightforward r&r, no a/c work involved:

Amazon has the radiator for $45 delivered 2-day/prime (it says "used" but it is an open box return or cosmetic blem):

https://www.amazon.com/gp/offer-listing/B000C7VYSI/ref=dp_olp_all_mbc?ie=UTF8&condition=all

Add a gallon each of the right blood type of Pentofrost and of distilled and you're done. $60.

A few years ago, my Element went through 2 radiators over the course of a few months. At that point, I found that there was a metal bracket that was loose that was rattling against the radiator, eventually causing it to leak through. I found the leak by using a pressure testing kit, saw exactly where the coolant was shooting out.

I didn't have time to do the replacement again, so what I did was empty out the coolant, then use some Quiksteel epoxy putty to put over the hole. I put the cooling system under a slight vacuum with a hand vacuum pump hoping to help suck in the epoxy. 2 years later, it's still holding. I expected it to start leaking after the first winter. I even bought a new radiator, I just haven't put it in.

I'd personally be a little worried about putting anything into the coolant to try seal the leak, just in case it damages anything else.

Replacing the radiator is the easy part. It's removing all the interference (such as cooling fan assemblies and radiator hoses/clamps) and reinstalling it that is the harder part. Coolant hoses and clamps can be a bit touchy when trying to remove/reinstall/reseal them. My mechanic charged me $600 for a radiator diagnosis and replace. Turned out the leak was from the internal transmission cooler. The radiator was cheap. The labor wasn't. If it happened again, I'd probably tackle the job myself - having to remove much of the front end of the car.

How much would it have been for the diagnosis without the replace ?
