What do you think of the silicone hoses and the TRD 1.3BAR cap??? Would that help in the summer? It increases the pressure - would that be ok for the radiator???
Reps given as usual!
I personally wouldn't bother with raising the pressure, The systems designed at 0.9 bar and generally copes ok so i wouldn't change it, Iv been running 0.9bar cap for over 3 years at 1.1bar on a hybrid and it's taken it no problem.
By that logic you shouldn't up the boost past standard as that is what the car is designed for.
That was exactly what I was thinking!!! But then, yes a lot of people drive without any changes to the coolant, but this can reduce the engine's life dramatically! It wasn't designed for it AGREED, nor it was to 1 BAR CT9 not to mention TD04. It works however!
But my car is by no means standard, my coolant system is, but everything bar the engine internals and inlet plenum is uprated. Not only to help it produce more power but to help the car run safer, so it's up to you as I said but I do know what im talking about no matter what starlet Sam may be trying to imply.
Also you mention td04 as if to imply it would put more load across the engine but actually the hybrid would create more heat at 1.1bar just FYI.
Cheers
Nah, I'm sure you're a genious but your logic on the cooling system is flawed if you don't modify it because it's not designed for it. Upping the pressure will allow the coolant to get hotter before it boils, that is all.
No, it won't magic more heat into it. It'll allow it to get hotter before it boils. If it boils you'll have gasses in your system which will create hotspots which will damage the engine, it'll also force coolant out of the system as steam takes more space than liquid. A 1.3bar cap will allow it to get to about 135 degrees before it boils, but of course it'll take your right foot and high ambient temps to get it there it won't just do it itself.Yeah, exactly, its not a good idea to up the temperature of the cooling system. Which upping the pressure will do..
Kind of defeats the object of the "cooling" system
as said get new thermostats, also i'd flush out the whole cooling system, including the heater matrix, you wouldn't believe the shit that gathers in there, and you should have loads of lovely heat then, toyota heaters are known for being very good. get that done and your sorted
On my experience, TRD doesn't make shitty mods, everything they make cost a fortune, but does improve whatever you replace!
Increasing the pressure will help to cool down the engine, but I don't want to do it on my car because of the gearbox, it's also connected to the radiator and that would mean that more pressure will go to the gearbox, I don't want that. By the way my radiator is double the thickness of the standard radiator!!!
I've been thinking about the design, why is the AC radiator is in front of the standard radiator? why is it so big? Have you touched it in the summer? It's always cold no matter what temperature outside! I assume it helps to cool the standard radiator as it is cold and the hot air in the summer passes through it and get's slightly cooled down!
I've seen under the bonnet after a good run on the hybrid of my mates, it's steaming!!! I'm not saying that it's hot, no it's not hot, it's EXTREMELY HOT! I bet that don't do any good to the engine!
Regarding the heater matrix - where is it located and how do I clean it???
Regarding the heaters - TRUST ME MATE, you can't be the VOLVO! -35C outside - I was sweating in a T-shirt inside the car!
On the other note - French cars....... SUCH a NIGHTMARE when it's cold, not only the diesel doesn't start properly, the heaters are horrible!
you'll find 2 pipes going into the bulkhead, pull both of those off and run some water in through one of them, it'll come out the other, run the water til it comes out clear, if your changing the thermostat, when its out run water through the other rad pipes, into the engine etc and flush the radiator , had to do it on a glanza i had, made a world of difference.
the gunk that came out was crazy
these are the pipes at the bulkhead
yeh we had near minus 20 here and not a bother to my diesel camry, toasty warm inside and started first turn
Thank you mate! Very good advise! AS I've changed the coolant already, do I have to drain the radiator now? or can I just flash the Matrix? Would the coolant be in those pipes? I've no idea how it works, but I would assume that it's connected to the radiator!
Below -20C - all the diesel cars would have BIG problems, unless the fuel tank has the heater or unless you use special WINTER type diesel!

You assume incorrectly. When the AC gasses get compressed it get hot, when they expand they cool dramatically and if the compressed gasses are already cold then they get seriously cold when they expand again. So the pump compresses it, the radiator cools it, and then it expands around the system again cooling the matrix and BAM, you have seriously cold air in the car. Exactly the same as your kitchen fridge. The radiator is there to cool the air con gasses, not cool the air going to the radiator.
@ Paul_JJ What turbo are you running in your car now and what turbo was in your old starlet
