Radiator Top Hose Modifications

So i have taken to putting in an aftermarket temp sensor and TEFBA inline filter into my cooling system. Naturally these both need to go into the top hose (outlet) which is sadly a very short and mildly convaluted.

I have modified the hose path to be able to get in the sensor uit and tefba filter with a set of hoses as shown.

I was just wondering from the people in the know (people just throwing out ideas and opinions try to hold back) if this is going to be ok and the cooling system is going to still work fine based on the hose path.

2 points worth noting.

-the hoses i have utilised are all sitting as per their original design. that is; there is no angles being forced on the hoses, nor any pulling or twisting going on that will cause the hose to crimp under heat/pressure.

-the hose is still always in an ascending gradient. it doesnt go up n down along its path from engine outlet to radiator inlet (see pics). it is still a steady upward gradient as per original design which im sure is necessary in coolant hoses.

This going to be fine or any reasons why not?

Obviously my main thought of issue is the 100 degree bend now utlised between the sensor and filter, which was not in the original RB25 design. However some cars do use such extreme bends in their radiator hosing so i can imagine why it would create and issue here...

cheers

Should be fine, but can I ask what purpose the filter serves? Naturally I can hazard a guess at what it does, but having seen a multitude of high performance engines and never coming across a filter in the cooling system before, I can't see why it would be necessary?

+1 for the inline filter.

If the cooling system is filled with the correct coolant, and replaced regularly; there is no need to filter anything.

Every joint you put in these hoses is just another potential point of failure.

Filter is good, Ive got one, when I had my engine rebuilt they installed one, it caught a heap of silicon and other shit from the rebuild, even though the motor was chemicaly cleaned it still got little bits of shit, mine is a RB25/30 so the block well over 20 yrs old, over that time no matter how good you maintain it the metals will breakdown, where does these little bits of rust and gunk go, through your water pump and/or blocking the cores of your radiator, unless you have a filter.

If they were not any use they wouldnt put them on new trucks and heavy plant, all our new trucks and heavy plant have colling system filters.

But if you happy to damage water pumps or have blockages in your radiator dont use one.

Engine rebuild 2 yrs ago (ish), coolant changed every oil change which is after every track day or on average 1000klm.

Track day tomorrow, this thread reminded me to check filter and clean.

Here is what it stops going through the system;

The proof is in the pudding.

couldnt agree more on the benefits of an in line radiator filter, the TEFBA filter has stainless mesh and is a quality item. . . im sure everyone knows here to use quality coolant and soft water but as just about all cars on this forum are secondhand who knows what the previous owner(s) have used in thier cooling systems?

why use one?!

this and this.

N iv had several skylines now n been through the joys of 2 clogging radiators. We have near on 20yr old cars now that are notorious for doing it...

Also im now running some higher power through it and i live in perth with out lovely 46 degree days in summer. Want that thing running properly...

fark yeah, for the cost of a radiator cleanout and the possibility of a cooked engine its good insurance to have a filter

it should be fine if its still below the air bleeder on your cooling system

yep. below the bleeder and even radiator cap.

CLeaned it out for the first time last night n the mesh was clear but the magnet had lost of rusty flake residue...

Glad this thing is there if it is removing this kind of gunk...

Will update this with comments as in the next few weeks im going to run a flush through the system so ill tell you what gets caught when i do that.

      Should I use rust converter on this?

      Should I use rust converter on this?

      By PranK · Posted

      One of the first jobs with the E39 is making sure the tailgate stays up. In BMW fashion they made a little cavity under the roof to hide the dampers rather than putting them down the side like everybody else.  As you can see I have these little cavities that house the dampers. When I cleared one out and vacuumed as much crap as I could out of it I noticed a fair bit of rust. The cavity is bone dry, even after all that rain we had only a few days ago so I'm assuming that whatever allowed the moisture in is fixed but I'd like to treat the rust in there.  I was thinking of just blasting it full of rust converter but I didn't know if this would be beneficial considering I can't actually get in there to prep anything.  Maybe there's a better product?  Thanks guys

      Help Understand GTT Boost Setup

      By GTSBoy · Posted

      The stock boost solenoid is just a valve. Power it and it is open. Unpowered, it is closed. When it is closed, there is no boost bleed out through the solenoid back to the inlet. The wastegate sees all the boost pressure, thus you get the wastegate's spring pressure as your boost pressure. 5 psi. When it is open, it lets some boost escape. This causes the static (boost) pressure in the line to the wastegate to be lower than the pressure in the intercooler pipe. There is probably a small restrictor in the solenoid or one of its lines to limit the flow rate of the escaping air, which limits how far the static pressure can fall, which limits the extra boost. The boost has to climb above the original/wastegate setpoint until the wastegate sees 5 psi. You get 7 psi in the intercooler pipework. A manual boost controller is exactly the same setup, just without the ability to change it on-off. It's always set to whatever you set it to. There is a small leak from the boost controller. The more you screw the adjuster in, the more it leaks, the lower the pressure seen at the wastegate and the higher the boost will be. So, yes, your diagrams are correct.

      Help Understand GTT Boost Setup

      By DraftySquash · Posted

      Hi everyone, Apologies in advance if this feels like a topic covered multiple times. I'm only asking because some of the old topics I found are missing images now. I'm in the process of getting a manual boost controller (BC). Nothing fancy, just getting a manual one for now as I don't plan to go crazy with it and would not go over 10 PSI. My car is not jacked up on boost steroids to do crazy numbers. I want to understand the OEM setup of the boost solenoid and vacuum lines on the R34 GTT so I know what needs to be changed when I do install the BC. I sketched the current setup to the best I could see and it's on the diagram attached. If the boost controller 'Wastegate Arrow' goes from nipple 1 to 2. My understanding is that the red vacuum line's "F" connector-end should be connected to BC nipple #2? Nipple #1 is meant to have the "pressure source" so what vacuum line would that be? Is it the green vacuum line?  From what I have read here, the OEM boost solenoid is not used at this point. So that can come out and then I can just plug the nipple that usually connects to the blue vacuum line?  So would the final setup look something like this?   Thanks in advance. I don't want to already be knee-deep into pulling out vacuum lines before understanding this. I'm a noob when it comes to boost setups so trying to learn as I go.
