Sharpie Posted August 19, 2003 Share Posted August 19, 2003 I did wonder if my TRD cap contributed to my Heater matrix going with the increased pressure before it would overflow. Stock is 1.1bar / TRD is 1.3bar as far as I can remember. I also have a small pipe split on me see pic. Do you think the TRD cap could have caused this with the extra pressure ? Seems logical..... Note: pic was taken 2 months before the Matrix went. Link to comment Share on other sites More sharing options...
baldy Posted August 19, 2003 Author Share Posted August 19, 2003 leon's only concern was where the rad plastics meet metal on the seems.he said i should go 4 the fluidine rad instead which also comes with a 1.3 cap Link to comment Share on other sites More sharing options...
Branners Posted August 19, 2003 Share Posted August 19, 2003 rad cap went on my import so I fitted a blitz one 2 years ago and the car has not had any problems with the radiator at all. JB Link to comment Share on other sites More sharing options...
Steve W Posted August 19, 2003 Share Posted August 19, 2003 the idea is that the Toyota/normal pressure cap ALLOWS release of pressure, ON PURPOSE, before any hose/rad/matrix weak points 'pop'... .....that's the idea behind having an EXPANSION bottle.... it's supposed to expand/contract into/out-of the bottle. it's OK to use a higher-pressure cap, but, it WILL put slightly more strain on all the cooling system components.... OK as long as they're all in good condition. [OTHERWISE, Toyota/manufacturers would put 'SOLID' caps on all their cooling systems ! ! ] Link to comment Share on other sites More sharing options...

Guest Terry S Posted August 20, 2003 Share Posted August 20, 2003 I brought 2 TRD Caps, one for me and one for Leon. Mine was fine for 6 Months but then my Electric fans packed up( shitty Kenlow stat) and instead of the cap blowing, the entire plastic top section of the rad split in two. The pressure was amazing. The water went through the bonnet vents and covered the entire car including the rear spoiler. This is where Leon's reservations come from. The second cap tested out OK, but by then I had a fluidyne. Stock caps go bad too, but the spring just gets weaker and you'll see bubbling in the expansion tank. Leon never fitted the TRD cap and just went straight for a Fluidyne. GReddy may be fine, and as I say the 2nd TRD one seem to operate fine too. Link to comment Share on other sites More sharing options...
400BHP Posted August 20, 2003 Share Posted August 20, 2003 Funny I should see this thread, my Cap has just gone, when I squeeze the top hose, the coolant is just squirting straight into the expansion vessel, not good. 10quid from toyota, gonna go get it soon.
