infamous nissan coolant issues HELP!

[katillidie]

Alright people..2000 frontier Ka24de got hotter then usual but not on H.. Replaced thermostat w/3 aftermarket now nissan, then lower hose would not get hot.. T stat not opening, bleeder screw on intake broken off by previous owner... Then i broke a easy out in said screw.. Use vacuum bleeder to add coolant which held vacuum. replaced water pump, radiator, and cap then hydro carbon tested the coolant came up positive for exhaust fumes in coolant... Replaced headgasket with completely new decked head.. After head and gasket install with arp head studs i vacumm bled the coolant. Vacuum bleeder held vacuum for 10 mins prior to releasing the valve. Still getting same symptoms, upper hose gets super hot and gurgles while lower hose stays ice cold.. Thought cracked block.. Yet no coolant in oil or vise versa, and holds vacuum, and holds pressure with coolant pressure tester when hot .. Is it just the infamous nissan air pocket or is my s*** fubar!

dril a 3/16 hole in the flang of the thermostat to let air bubbles through

then find the steepest hill you can and park nose up hill turn your heater on full and try to bleed the air out of the cooling system giveing it some bursts of revs (dont rev the hell out of it)

[katillidie]

Are u saying to remove relief valve and make the hole bigger or keep the relief valve and drill a second hole

Good Deal. I've been reading along, and was wondering how to get that Stuck Stud out. They may have used some Red Locktite, or it may be rusted in place. I was taking the control's off of a Motorbike HandleBar once,, and they had Red Locktite on the center bolt holding the hand hold's. It's a miracle,, I got those bolt out.

You did good,, and I didn't even think of Drilling another Air Bleed hole.

Sound's to me, like you are the one that doesn't know.

On that Engine,, there is a Air Bleed Screw,, that was broken off,, and then the Easy Out Broke off as well.

The Remark's that you took the time to expell were not needed at all.

The Avatar that you have,, explains your Attitude as well.

true i have not worked on that particular motor but i have been in the trade for 25+ years tho (not including apprenticeship and 4 years with a Formula Vee team)

yes i read that and your point is?

i have worked on lots of cars / trucks that have bleeders on the cooling system and a lot of them are non functional for one reason or another and the process i have described is one of the best ways to get around the problem

i didnt see you helping

The Remark's that you took the time to expell were not needed at all.

look at what you just did and you didnt help at all and you attacked someone as well

well done

The Avatar that you have,, explains your Attitude as well.

at lest i took the time to fill out my profile instead of just doing as little as possible to get in to a forum and act like a troll like some people

All that may be True,, but in this Case, No Advice from you would have been better.

yes i read that and your point is?

I had the KA24E Version of that Engine,, and the Air Bleed Screw, Functioned as described in the Service Manual. Seemed to me that You were trying to get him to modify his Thermostat.

All that may be True as Well, However Adviseing Someone to Drive to the Nearest Hill and Burp the Air Out of The Cooling System Could well have done Damage to His Engine.

While Driveing to that Socalled Hill,, that Engine could and probably would have Spiked to an OverHeated Engine. That's why they put the Air Bleeder Screw, for that Engine. If You want to use your method, then Jacking up the Front End would be better,, cause if an Over Hot Engine Spike occur's,, you can shut the Engine off in a hurry.

Your Method may very well have them sitting on the Side of the Road,, Trying to figure out what now.

i didnt see you helping

No Advice is Better than Bad Advice.

If you had read just a little bit about the "OP",, you would have seen straight away,, that he is not a Novice.

^^That Thread, tell's me that the OP is not a novice ^^

You were the First to be Disrespectful. You know how to "Dish It",, but have a hard time "Takeing It".

[Adverse Effects]

well lots of things to say but i dont need to turn it in to a slinging match like some i wont post again in this thread unless asked a question

PS :- BRubble excluded

[katillidie]

bleeder screw... had to remove the intake manifold. drill a new hole to relocate the screw... once that was complete u could hear the air escape... thank u for ur help

[BRubble]

Great, I knew you could do it, after I read your other Thread putting on the DOHC in place of the SOHC.

Amazing to see someone post how they made it work.

The Air Bleed Screw,, alway's came out easy over the 20 year's that I had a ka24e. Previous Owner probly went over board with some sort of Sealant or Glue.

I sure wish the VQ40DE that I have now was as simple to work on.

Thank's for shareing.

[katillidie]

i didnt put a dohc in place of the sohc... the 2000 frontier has a dohc ka24de in it from the factory... the block is essentially a sohc that nissan put a dohc head on... the head differs from the s-chassis head only by there is no last cam journal... but i wasnt sure if it would actually bolt up... but it did..

[BRubble]

It sure look's professional to me.

That's complicated stuff,, getting the timeing mark's lined up correctly on the Cam's.

I've seen other thread's that were complicated like that and the OP, said that it help's them double check themselve's by takeing picture's and doing a write up, as well as helping other's that might have to do this too.

Thank's for shareing
