hadyn Posted December 14, 2007 Share Posted December 14, 2007 Hi all, Tommorow im getting a new radiator fitted to my tt. To finish it off i might put a 1.3 bar rad cap(trd blitz etc) on the new rad. I think I read somewhere that these caps can put extra strain on the cooling system. What exactly is put under strain when you fit an uprated cap? Im presuming I might be OK with a new rad and all?

Wez Posted December 14, 2007 Share Posted December 14, 2007 About 1.3bar maybe Link to comment Share on other sites More sharing options...
R Black Posted December 14, 2007 Share Posted December 14, 2007 About 1.3bar maybe Cheeky fecker but i like it Link to comment Share on other sites More sharing options...
Wez Posted December 14, 2007 Share Posted December 14, 2007 On a serious note, increasing the pressure raises the boiling point Link to comment Share on other sites More sharing options...
hadyn Posted December 14, 2007 Author Share Posted December 14, 2007 On a serious note, increasing the pressure raises the boiling point Exactly. Never had an issue on my 200SX when I used to run a blitz rad cap. Thing is although the rad will be new tommorow, the rest of the cooling system is like 15 years old. Im just wondering if putting one of these caps on will cause any kind of failure in the near future? Link to comment Share on other sites More sharing options...
Scooter Posted December 14, 2007 Share Posted December 14, 2007 my question would be why bother? why not fit a stock one? Link to comment Share on other sites More sharing options...
Terminator Posted December 14, 2007 Share Posted December 14, 2007 I suspect that any new cap will be better than the original if it is the same age as the radiator. When my rad cap failed, I got no warning, just a pool of coolant on the drive. When I took it off it was in several bits. An increase in pressure will show up any weakness already in the system. Unless you have weaping hoses already I doubt you will have any problem. I went from a Toyota three piece rad cap to a Greddy 1.3 bar on a 1995 water system with no issues.

hadyn Posted December 14, 2007 Author Share Posted December 14, 2007 Fitted a brand new stock cap last year as a precaution. My turbo coolant hoses have already perished this year - so the only thing to worry about is hoses etc going?? Im only interested in fitting one as they're supposed to make your rad cool a bit more efficiently by raising the boiling point... Link to comment Share on other sites More sharing options...
Digsy Posted December 15, 2007 Share Posted December 15, 2007 Im only interested in fitting one as they're supposed to make your rad cool a bit more efficiently by raising the boiling point... No, they allow you to run your engine hotter without it boiling over. If you suspect your coolant is boiling then it would make a difference. If not, then it won't.

JohnA Posted December 17, 2007 Share Posted December 17, 2007 However:innocent:, if I were suspecting that my coolant is boiling I'd rather find the root of the problem, instead of masking it up by raising the boiling point. There is a lot at stake, isn't there? Link to comment Share on other sites More sharing options...
hadyn Posted December 17, 2007 Author Share Posted December 17, 2007 So to summarise, raising the pressure of a cap to 1.3 bar from 1.1 bar on healthy engine and cooling system, has absolutely no performance benefit whatsoever??? Link to comment Share on other sites More sharing options...

Uness there's some physics at work that I'm unaware of, that would be my take on it. Link to comment Share on other sites More sharing options...

What did you expect, a few tenths on the quarter mile? Maybe it will give some short-term extra headroom in case of overheating. That's it.

Ryan.G Posted December 17, 2007 Share Posted December 17, 2007 Im not a fan of them TBH as although it does show any weak spots in the system ie leakes etc i also feel they can cause the failing of Heater matrix's with the added pressure. Waste of money in my mind Ryan Link to comment Share on other sites More sharing options...
