Gaz Walker Posted March 14, 2008 Share Posted March 14, 2008 They are rated to 1.3 bar rather than 0.9 bar. Increasing pressure in the cooling system increases the boiling point of the coolant. Higher boiling point means that the coolant in the rad is hotter and therefore has a higher differential temperature between that and the air being pulled through it. This in turn means more of the heat is transferred into the air and therefore taken away from the engine. Link to comment Share on other sites More sharing options...
Guest Gaz Shaw Posted March 14, 2008 Share Posted March 14, 2008 so def worth gettin? its £30! i got a j-spec n/a manual M reg cos it goes on about s type or N type ones? Link to comment Share on other sites More sharing options...
Scott Posted March 14, 2008 Share Posted March 14, 2008 If your going to be pushing your engine a bit more than daily driving then i would say its worth it. Scott =op Link to comment Share on other sites More sharing options...

Scott Posted March 14, 2008 Share Posted March 14, 2008 wow i always thought they were for kinda dressing the engine, to look pretty. Learn something new everyday. They are really, unless you are pushing the car hard and boiling your coolant a lot. Scott =op Link to comment Share on other sites More sharing options...

Homer Posted March 14, 2008 Share Posted March 14, 2008 I wouldn't recommend one if you are still using an original stock radiator. The cooling system pressure is raised significantly and in quite a few cars the dreaded hairline cracks have started appearing in the top of the rad a short time after fitting one. This has happened on cars with 10yr+ old radiators. They're pointless IMO Link to comment Share on other sites More sharing options...
Guest Gaz Shaw Posted March 14, 2008 Share Posted March 14, 2008 Hhhmmmm:innocent: well i dont really need to change my rad cos in not racing or anything or shall i? will it be worth doin and what type is best? Link to comment Share on other sites More sharing options...

This has happened on cars with 10yr+ old radiators. They're pointless IMO Very good point. Never thought about the age of most of the rad's. I think a stock rad would be ok though, would just need to be a newish/good condition one. Scott =op Link to comment Share on other sites More sharing options...

Jake Posted March 14, 2008 Share Posted March 14, 2008 Gaz, Ask anyone who's ever had to change a Supra heater matrix what they think of TRD fukcing rad caps! Link to comment Share on other sites More sharing options...
Chris Wilson Posted March 14, 2008 Share Posted March 14, 2008 Quite apart from the rad, which is relatively cheap to replace, increasing the cooling system pressure on an old car with well documented heater matrix failure problems is not wise. Unless you lose coolant to the expansion tank through boiling, which will not happen on the road, with a cooling system in factory stock, good condition, it's a gimmick anyway. Just make a TRD sticker for your stock cap and lie to people about the racing cooling system Link to comment Share on other sites More sharing options...

They're pointless IMO I wish this tread had been started a couple of weeks ago New TRD rad cap, stock rad, hairline crack to top of rad New rad, fans fitted more expenses Butt a nice shiny new rad when done TRD rad caps should be sold with a warning sticker or the trader selling them warning the buyer he may be on the road to spending even more!
