It really worked for me too,,, it’s been four years no prob at all till now ,,,

[@suzannesquivel1632]

Thank you. I'm 65 female on a small income. It would take me 4 months to save $1000 to fix at pep boys. I have a hairline crack in plastic radiator just below the big hose. I'm going to do this quick fix until I can save for new radiator if needed. Unless it fixes it permanently. I've no family. So this is my choice. Thanks again. It's a 2004 jeep grand Cherokee Laredo

Hi Suzanne! i'm in same predicament... curious to see if it worked for you? :)

[@marioexpropiacionpetronilo2753]

Nice video!!! Clearly explained, and you showed the engine running at operating temp ( most videos I've seen didn't). Thank you!!! Short and sweet.

[@user-BossMan]

3:10 MY WIFE REFUSED TO! 😂 Smart wife! Lol! She said repair it RIGHT! With J.B.Weld!! 😂😂😂

[@clixstormdiy4352]

Update: 8,000 miles later still holding.

[@CannonMan391]

Thanks brother, this is exactly what I was looking for.

[@Techisol]

@@CannonMan391 I've been looking for the same confirmation. Thanks!

[@martyjoseph9507]

Thanks for the update. I've got a real beater that hopefully can be on the road another 2 years, it just keeps starting and going. Not long enough to invest in a new radiator so hopefully a patch will work, just trying to figure out the best one.

[@bigjg904]

Tnx for sharing. My 98 Ford explorer top hose fitting just broke off while trying to tighten the clamp. Smh!! Just looking for ways to patch it up till the first of the month.

[@MrJupton1]

Great help! have same issue..97 Camry...Plastic cracked radiator... will give it a go! Thanks

[@dwayne0t]

What about if I snapped off the part where the radiator hose pushes on to, do you think it could work?

[@zxbzxb]

The biggest issue is the plastic radiator will deform and expand the crack once pressure buildup, especially the crack extends long enough. That's what happened on my radiator. Tried jb weld, doesn't work well

[@chrissy6569]

Tireman told me 600$ for new raider I was over heating cause I have a crack in my radiator I’m gonna go to auto zone to get the stop leak will it make my heater start working better again

[@beethoven8256]

What's the amount of the Bars Stop Leak you used?

[@phall7031]

How about using a patch made of appropriate material to apply to the outside of the break as reinforcement after joining the parts? Would be like doubling the wall thickness in the weakened area.

[@clixstormdiy4352]

I hadn't thought about that but see your ingenuity would have worked. I was using things I had access too. But I will keep that in mind.

[@americafirst2785]

That bars leak will clog you heater core,be warned.

[@hnajee]

Very educational for me. Unfortunately we don’t have JB Weld and Bar here. Will PC Fahrenheight Hi Temp work on a small crack of plastic crack . Will appreciate

[@clixstormdiy4352]

You need a solvent that hardens but has some flex to it. A tiny amount to give to driving engine heat.

[@vidablanks4669]

I have a Ford Escape where the radiator cap is not accessible. My reservoir is where I add coolant.. I put the stop leak in the reservoir. Temperature gauge still running hot with coolant full? Help

[@AlexGarcia-vv4ux]

My 2001 Acura MDX has a crack in the exact same spot and at 168,000 miles going to try this .

[@clixstormdiy4352]

Prep a rough surface as much as you can. Take your time and do it in layers.

[@AlexGarcia-vv4ux]

Clixstorm DIY sadly it didn’t work out for me I did 3 layers let it sit for 2 whole days and for some reason not sure why but it made it worse didn’t last more than few hours before it looked like tea kettle shooting steam out of it.

[@ronaldvazquez4373]

Didn’t work for my situation. My leak was at the inlet to the upper hose an I’m guess there is a lot of pressure and in that location it is very hot. Trying to use a high temperature self adhering silicone tape.

[@butchromig824]

the tank gets corroded on the inside from the hot water pushing against it,stopleak is great for plugging up the radiator!!! temp patch for sure

[@Mid-Ohio]

Similar to my crack….what’s the current update

[@bringthefresh4094]

Still holding up?

[@dannysmith6035]

Was ur radiator leaking on bottom like mine is ?

[@clixstormdiy4352]

Yes. Leaking from crack to the bottom

[@aprilmansanares1384]

is the solution still holding up well? I'm trying to fix up my radiator

[@clixstormdiy4352]

April Mansanares it's still holding. With all the heat, it's okay.

[@bigbosscaos3923]

After I just bought a new radiator :/

[@Butchsiek]

never put any thing in the radiator to stop a leak.. it will plug coolant passages and the tubes in the radiator, if they are partially blocked, the stop leak will block it the rest of the way.. same with the heater core.. not to mention heater valves.. also it can affect the thermostat..

[@clixstormdiy4352]

I'm The Law if you are unsure, rapir only the crack from the outside.

[@Butchsiek]

First off i used to rebuild/repair radiators and even repaired heater cores that radiator shops claim they cant be repaired.. which is a lie to sell a new core.. more profit.. Plastic Radiators degrade over time based on heat and time.. as the older the plastic radiator ( a Nylon Composite) gets and hot, it degrades, mainly around the intake side of the radiator and becomes soft.. so repairing the crack is basically a temporary fix but can last a long time, depending on the age an how hot it gets.. Im replacing a radiator that is 22 years old 180,000 miles and the plastic around the intake side where its cracked, can be scraped off with my finger nail.. that is really soft.. I wouldnt fix it unless the plastic is hard.. when repairing plastic never use epoxy because it can come off, due to the fact moisture from the crack, can get underneath the epoxy and cause it to separate from the repair.. one guy suggested using Crazy Glue and baking soda as it becomes rock hard.. but i dont know if it is porous or not.. or if it will stick to the radiator.. for metal, you are right, if it can be fixed, personally i like to use expensive metal, silver solder.. I can use a bottle of map gas or propane.. but 50/50 is what I used in a shop setting..

[@jgfrakes2736]

General Motors recommends radiator sealant wafers, which will seal just about any leaking cooling system in a vehicle. They put them in all of their vehicles right after they roll them off of the factory floor and first fire the engines. That being said, putting multiple sealants into your cooling system can clog it up, making the issue of a leaking radiator the least of your problems, because now you have insufficient coolant going through to the motor, and you will overheat. Overheating a modern engine is death.

[@Mr2pint]

Nearly all radiators are made of plastic these days even on high-end cars. If you get a crack in your radiator replace it, they're not that expensive and relatively easy to do yourself.

[@clixstormdiy4352]

What about those on Governments Shut down or unemployment. You assume everyone can afford $200. 67million different lives in the USA. Probly a few who can't. Im still driving the car on these cheap repairs.

[@Mr2pint]

@@clixstormdiy4352 fairpoint and yes you do what you have to do to survive. All the best.

[@jeffreybass5500]

Agreed.

[@scottconnors8419]

there nylon substrates...

[@suzannesquivel1632]

Yes it is expensive. Pep boys wants to charge me 900-1000 for a new radiator. I'm on a small set income. No family. It's a small hairline crack just below the big hose connection to radiator I wiped it and can feel the crack with my finger. I can see it leaks . But if this quick fix with jb works it will buy me time 4 months just to save 1000.

[@bluuedaniel]

Why did you put this crap in when you had the actual leak was fixed. It can plug heater radiator core, and the main radiator passages.

[@daniellima2973]

Spend 10 more and buy QBond

[@lovetrump1088]

It would help if you showed the process...otherwise, it's just words with a video of a radiator. Oh, and pics of Bars Leak - missed the whole HOW TO part of all of it.

[@clixstormdiy4352]

Pour it in.

[@got5at12]

temoary fix it will clog the therstat up.

[@Tonio_562]

Mine is just like that. I used the weld it worked for a while and then the crack came back out I used the jd weld again and it's cracked again!!!

[@clixstormdiy4352]

Preparation is key. Another comment suggested fiberglass tape to help hold the crack.

[@otisbailey5455]

Radiator replacement are not that expensive, replace the radiator or have one that may fail when you are on the road.
