Hi all,
Just wondering which radiator sealer stuff is ok for a rotary as I know quite a few are no nos due to them blocking up the water passages in the block!
Basically my coolent buzzer has just gone off again, not sure how much water has gone but I need to rule out the radiator before I get the engine rebuilt if its waterseals.
This has only started happening since I changed the rad over, I can\'t see any obvious leaks from either hose - the engine bay needs a clean so its slightly dusty meaning I can see leaks lol
Which sealers are ok for me to put into the system and leave?
k-seal.....?
I know there are lots of rad sealers but I need to make sure its rotary friendly first :rollin
the metal bit are really small and a few people on here have used it before with success in sealing the rad.
My personal experience of rad seals would lead me to tentatively suggest that you DON\'T USE THEM UNDER ANY CIRCUMSTANCES :Nono!
This is the state of the cooling system on my daily MR2 after some barbarian tried to bodge it with rad seal....repeatedly. Seriously, find the leak and fix it properly, it may be aggravating but believe me, it\'ll be less aggravating than digging gunge like this out of metres of coolant system :yes

Big difference between using it once and replacing the bloomin coolant in it\'s entirity!
I used the stuff Mazda Rotary Parts sells back in March last year- it\'s held ever since, including an absolute beasting at the \'Ring where my water temps hit 120!
Still runs sweetly, I\'m just waiting on my new rad getting delivered, but I\'ll post pictures if there is a real mess.
k seal is the one that people use in rotarys...

I personally don\'t want to use any, it might just be the sensor bung on the top of the rad though, so I will re-seal that, but it might just be water seal failure :rollin awesome
try k seal! it doesnt make a gunk like that, its just a liquid with small bits of copper in it... it goes in to cracks and forms a copper seal... thats all... mrp sell and recomend it!
I just read this on the k-seal website:
K-SEAL® OR SEAL-UP? What is the difference between Seal-Up and K-Seal®?
Seal-Up is the original cooling system formula and is based on Sodium Silicate technology. This is very effective at sealing leaks throughout the cooling system but it has one drawback. If Seal-Up mixes with antifreeze and is heated then a reaction can occur leading to coagulation of the compounds in the cooling system and potentially causing blockages. As a result it is essential that the system is drained before and after treatment (as per the instructions on the product). It is not necessary to use any special flushing products but some users like to run water through the system after draining it.
K-Seal® is a newer formula which has proved to be as effective as Seal-Up but has the added advantage of being compatible with all known types of antifreeze. As a result the product can be added directly to the cooling system without any special preparation. It can even be used as a preventative additive where no problems are present.
We continue to stock both products because Seal-Up still has an excellent reputation and loyal customer base with the trade. K-Seal® is now by far our most successful product and has become popular with the general public, trade and many enthusiasts clubs.
If you have to try K-seal - get it from GSF, it\'s the cheapest place I\'ve seen it.
However, as Mr Nik says - I wouldn\'t touch it. If you think it\'s your rad, replace the rad.
Get a pressure tester, and pressurise the system. Then you\'ll find the leak.
Yeah im going to check the rad over, might just be a slightly leaking drain plug maybe, I will check over the drain plugs on the rad and engine, the hoses are both dry but my engine doesn\'t sound like a tractor which is good, its just annoying as the rad seems fine :(
more than one rotary builder on here has said k seal is good and fine to use... hayward being one of them iirc
Jesus Mr Da Greek - what the hell???? Did the engine fail, or did it still live even with all that crap in it??? That\'s amazing....
I can imagine it was a hoot digging all that crap out of the 47,241 miles of an MR2\'s cooling system...

Ohhhhh, yuss! :Giggle It\'s an indestructible Toyota lump, short of the cambelt snapping and it eating its head there\'s not much that\'ll kill one outright. 148k miles and still going string, although it does sound like a diesel tractor :mmmm

Yes, it\'s was a lot more fun than fduking a monkey :3Confused Took a
lot of flushing, just hours of skooshing it all through with a hosepipe and running it up to temp, then cooling it down and flushing through again. Amazingly, it eventually managed to free up both the vent/bleed screws in the heater matrix and the rad, so even the Hose From Hell survived, and believe me, if you want to avoid one job on a Mister Two it\'s that one :eek:
There should be like an RSPCA for people that abuse cars like the barbarian who did that to the cooling system; they should be banned from ever owning another vehicle because of their abhorrent cruelty or something
ha ha mate of mine got a civic and we took a door card off to find egg shells... LOADS of them... i took the rad cap off just to check and it was full of egg lol!
I just bought some K seal to try and fix the leak on my heater matrix. It\'s only a small leak so Im hoping for a good result. I\'ll let you know how it goes mate.
