head gasket sealer

Asked by Apr 04, 2017 at 07:16 AM about the 2000 Mitsubishi Eclipse

Question type: Maintenance & Repair

Just purchased a 2000 mitsubishi eclipse....well my son did (first car).  After
driving 2 days took it to the shop cause temp. gauge was high and found
out there is a bad head gasket.  Car was inspected 2 weeks prior to his
Mechanic quoted us 900-1500 w/out any promises on the car because of
its age.  Car was 1800.  He is either going to sell it for scrap or I though
maybe trying the sealer to see if he can at least have a car for a couple
months.   Any advice:(

I have tried many sealers over the years and none worked as claimed until I tried Red Devil, it did work temporarily, make sure you follow the directions exactly, and I also found a very low pressure radiator cap and ran that, it lasted about 3 months.


The correct repair of an issue like this is always the best option. If the leak is small a head gasket sealer product might work. Be sure to follow the instructions that come with the product exactly. Go for it, what have you got to lose. Let us know if it works and which product you used.


Morning people, I had a head gasket leak on a Ford Ranger before, all aluminum engine, and I used the Barrs Leak pellets on it. I ran that truck every day for another 2 years without a problem. I have heard a lot about the Red Devil product, Just wondering your opinion on the two products. I don't recommend doing this, but there are cases you have no choice, like this one, cost more to repair than the vehicle is worth.


Morning Rowefast, I have used Bars leak pellets also but did not have the luck you did, had to back flush it all out. However I have had good luck with it stopping heater core and minor radiator leaks.


Red Devil it is...if it ever comes to that for a customer. Thanks.
