Water temp issue

[Duncan]

great to hear it is sorted properly and an easy fix.  don't worry about the temp until it is north of 100.  the warmer they are they better they run, particularly in modern engines.

and score 1 point to Calln to guessing correctly

Should i bother draining water just from the radiator and keep doing it every few days til the drained water looks cleaner? Thanks

Drain and remove radiator

Remove thermostat

Run water through the engine until it's clean

Run water through radiator until clean (reverse direction, I think through the bottom?)

Reinstall radiator, thermostat, hoses etc.

Fill with appropriate water/antifreeze or whatever coolant, bleed via chopped drink bottle

Also dont forget heater hoses (flush the heater core) generally flushing the normal way works fine but I like to flush everything

82 is more than fine on cruise. 76 degrees is when the std thermo starts to open remember so your never going to keep it at 76. Mine used to do about 80-82 on a cold night from memory so id say your doing alright

I thought I'll do fine by just draining from the radiator and adding water. Keep doing that every day till water looks clean then use coolant. .. too much work to remove rad and stat...

But seriously will my idea work? Will most if not all water in the engine block be cycled out?

Reverse flushing with a hose will dislodge more cr@p than just relying on gravity.

Any DIY guide in sau? Really interested in doing this if that's the proper way. ..

Will a radiator flush remove those crap? I actually still have a bottle of liquimoly flush that I've bought like 5 years ago but was reluctant to use it because of stories like it eating seals away etc but what do i know?

Flush with water. You can't remove everything without taking out the end tanks or simply buying a new radiator, but reverse flush should be enough.

I can't remember seeing a guide, but set aside a full day to do it. Run with a thermostat, it's there for a reason, running without it means your engine takes longer to heat up. Nismo thermostat is unnecessary, standard is fine. Your engine should be around 80-90°C.

Guys quick one. .. so i used a damn flush and now there's a lot of bubbles in my cooling system. .. can i just remove the bleeder valve at the top and let all the small bubbles flow out? Injector is just below it so a bit worried. ..

 

yesterday i went for a quick drive and noticed the temp needle was a bit weird. .. do u think my motors head is warped due to bubbles ? :| only went for about 20 minutes drive though. ..

Bubbles? Like air bubbles or soap bubbles?

You did flush it with water after using whatever flushing agent you used?
And put coolant in afterwards? And bled it correctly?

Good question. Soap bubbles. My plan is to flush and replace water til the soap bubbles are gone. I figure out another 2 times. .. But so can i just remove the bleeder valve and let all the soap bubbles out? Will that be an issue as the injector is below?

Also was the third flush since using the radiator flush. ..

U seem to know something lol. Ìm still seeing f**king foam in the bleed valve. I just use plain water after using the flushing agent! It's like the 6th time after the flush and I'm still seeing foam! What am i doing wrong ?

I did warm up to make sure the thermo is open. The foam just won't go!!! [emoji35]

Pull the thermostat out and flush it. Stick the hose in there and let it flow for 15mins or so have the ignition on (not started obviously) and have the heater on to make sure you get anything out of the heater core also. Even better, pull one of the heater lines off and flush through the core that way

^^^what he said. Just pouring things down the radiator filler won't do it.

Pissing me off... after more than 55 liters of RO water!!!!! f**king flush just won't get diluted. the time, money and water i wasted... guess I'll try that thermostat one! !!!

My heater is removed by the mechanic that did the transplant. I see 2 pipe holes on the fire wall on passenger side.

Reason why i hesitated on using hose method was that i didn't want to use tap water. Imagine how difficult a small bottle of chemical to be removed let alone tap water?

Btw my understanding is remove the lower rad hose and thermostat and stick a running hose through the thermo housing? Don't need to start the engine. Water will flow out lower radiator . Correct?

Erm just got back from the mechanic. .. let me guess. .. you're asking bubbles or soap bubbles. ..

Can i guess if I'm seeing bubbles... means i have a blown head gasket?

Mechanic showed me bubbles when car was running and radiator Cap removed...

Man i knew that flush was a bad decision but then again i guess its just a matter of time. The flush just unmasked the issue ...

[89CAL]

That was my suspicion. But i know some people use laundry powder to flush sometimes so thought they may have been soapy bubbles

That sucks anyway but at least you know the problem now.

[-S-]

Yeah reading that other dudes blown neo head gasket thread now. Lol . Really hoping its just the head gasket. .. thing is temperature wasnt crazy hot. Guess the Trust radiator is better than the stock radiator. .. but who knows. ..
