Hey guys long story short i have changed my radiator , thermostat , radiator hoses , radiator cap and water pump and since then my overflow bottle has gone bone dry 2 times and im freaking out as i have checked my oil cap and its not milky and the fact that i have basically changed the whole cooling system and this is happening.

has anyone else had this same problem or know what it could be cos from what iv seen i cant see any coolant leaking.

long story short i bought this car and it sat for 1 year as i was still on my ps and when i was getting a power steering belt changed i later on realised something must of hit the standard radiator and there was a hole so i swapped it out for a just jap one. upon getting my fulls i got it tuned there was a hairline crack in the water pump so that was swapped out and i thought id might as well do the thermostat as the rest of the cooling system was new

hey you bleed the cooling system of air... it could be just bleeding the air from the system and using the coolant from the overflow like it should.

cheers sam

system was bled and filled up after so i doubt it could be that.

If its not leaking on the ground then its probably going in a cylinder,most probably a head gasket.Check the spark plugs,if ones a bit chalky then thats the cylinder

coming to think of it i have had a really bad misfiring on idle so i will def give the spark plugs a check tomorrow

Could be air still working itself through the system keep on filling up and hope it stops, give it 5 more cold start-ups to be sure.

This happened to me, more then twice when i went for a drive checked the coolant in the morning and nothing was in the overflow

turned out my radiator cap was shot and no pressure was in my hoses (check for pressure in yours) changed it and 2-3 times after that it did the same

thing just not as bad and i just kept on feeling her up until coolant stayed. I reckon air still in the system ! i was afraid my head gasket or worse

cracked block was the problem, thank god it wasn't.

poppedd in to my mechanics today he is leaning towards a air leak as when he put more fuel into the tune the car started to idle better.

so its going in next monday for a smoke test and a pressure test on the cooling system

It still needs bleeding there hard to bleed. I keep bleeding it then let it cool down and check overflow bottle until level stablizes takes close to 10 times til fully bled so nothing to worry about, either keep topping it up til it stops losing or bleed it.

      R33 general questions

      By Kaptain · Posted

      Im not entirely sure exactly what or where its leaking from, he started to pull the boots to swap to my new tie rods + ends and it just vomited fluid, so he closed em up up, swapped the rod ends to the old rods and let me know so I can figure a solution out, im guessing its all origional as as I passed 103k miles earlier this year im sure its just in need of a full overhual/rebuild anyways.    If i could just yank it off and be good it wouldn't be an issue to ship it out and wait for the turnaround but the guy I work with doesnt really have space to keep my car for a week or two at a time, would rather drop it off and have a replacement ready to drop in

      What do you mean by "seals"? Internal hydraulic seals (ie, is it leaking PS fluid?) or the rack boots that close the rack onto the tie-rods? Because the former is a rebuild, and the latter is trivial that you or any nearby mechanic could do. Dunno about the cowl. Just buy what you think is required and get anything else you find/break afterwards. Wing? Dunno. Don't like R33s enough to pay attention to them. Mirror glass is just glass (on the surface that you want to polish). Go for it.

      R33 general questions

      By Kaptain · Posted

      Hello! Long time lurker, been using the forums to address concerns and questions from afar for a while but I've struggled to find some answers so I guess its about time I made an account and formally asked some more knowledgeable people, since finding local skyline owners is hard (and shops that are knowledgeable or trustworthy to work on 'rare' cars are non existent out where im at, as skylines are quite uncommon to find in the wild around here). So the main 3 questions I have, 1: Steering rack has blown seals, well.. they kind of hold but they are not sealed properly anymore and as my R33 is my DD, i cant exactly rip the rack out and send it off or attempt to fix myself. As most refurb ones are around $1,100 or more shipped, and I have other things I need to work on around the car, I was seeking clarification on whether an S15 rack will more or less bolt right in, and whether a common mechanic could do any other required work to get it to fit. I ask, as I've found a supplier than can sell a manufactured as oem one for around 400, if not I'll likely order a used one from Jacks JDM, and take a risk on the seals there. The second question i have is that im replacing the front wiper cowl and have planned to buy 4 new clips and a new center clip but wasnt sure if there were any other clips that would also need to get replaced while I was at it. Given im sure any that are there now will simply break when I remove the old cowl... Last thing would be a fairly straight forward question, i think. If I manage (strong if, finding one has proven to be a pain) to find a R33 GTR spoiler/wing will it require much modification to bolt to a S2 R33 GTST? I've read the bolt patterns dont match but otherwise would bolt in, only options I have found with much luck is China stuff on ebay and carbonetics, which has a nice $650 shipping fee... so if anyone has any pointers where a US chap could locate one that would be great Random side question as well, the mirrors as I understand are mirror glass, and as im planning to polish my windows from water spots and surface scratches, i was hopeful cerium oxide would be fine for them too, as my research points to, but clarification is always nice. Any pointers would be appreciated, and while I have scoured the internet for answers if I missed a prior post somewhere that may answer these directly please point me towards it, as i must have simply missed it. I have seen a post here or there that has mentioned it, but I usually get 50-50 answers, or half answers... I dont have a lot of fab experience or mechanic experience, outside of hydraulic and pneumatic stuff I did in the military and with how hard it is to source stuff in the US, id rather not wing it and hemmoraghe money lol. Thanks guys! Sorry for the monumental first post haha

      Did tie rods. Steering now not "springing" back.

      Yep, there's a very minor drift left that happens a few seconds after letting go of the steering wheel, but not enough to bother me. Enjoying the car still!
