Coolant Issue R33

[gL3nJaMiN88]

hey guys first things first , i'm having issues with my water pump i just got installed around 2 months ago .. As i work for autobarn i picked up a waterpump (TrueFlow) which is made in japan , so i thought for only 60 bucks what a good price .. I only just recently pulled of cam cover to find it looks like it has been leaking on the side where the pulley is . . I took it back to the mechanic and he told me the issue is that one of the bolts from the water pump doesn't match up to the block .. He thinks its an rb30 so im not gettin a good seal ? Is this ok to leave or should a fix it asap, obviously he isn't gonna help me out or anything .. Also on my power Fc my car is showing a water temp of around 85*c on normal driving but when a give it some loving it gets up to around 105-110*c and stays around that.. The gauge on dash seems to be in place it has always read ? Can anyone help me out with some info on my issues , cheers

105-100 is a bit high. i think better get a nissan water pump.

RB30, RB20, RB25 water pumps all the same.

Sounds like you're not getting a seal because he didn't blue-maxx the shit right whoever did the work, and hasn't tightened it enough.

drain the coolant, rip off the cover again, undo the belt and pulley, unbolt the water pump, clean off the old silicone shit, replace with new Loctite Blue-Maxx silicone around all of the stud and bolt holes and around the entire sealing surface. not too much, but enough to seal the entire thing. pop it back on, tighten it up until it's juuuuust tight. then nip it up. replace all your bits, tension your belt via alternator. open the bleed screw on top of your manifold, take it out but don't lose it. fill the radiator with coolant (red if you're running red, green if you're running green). leave the cap off and start the car. let it run, and keep on topping it. run it until the thermostat opens, and keep topping it up until you can't fit anymore into the radiator. then tighten the screw back on (easier when the car is off) and pop on your rad cap. fill up your overflow to half way and job's done.

truflow is a good brand, and better than powermax. but no substitute for an N1 GT-R water pump, genuine. GT-R Water Pumps are anti-cavitation water pumps, but still fit the entire RB range of engines.

normal temp should be between 76-82 and up to 90 when pushing personally i cut it off at 95 so 110 is wayyyyy too hot!!

the dash gauge is crap and unreliable.

plently of people use the rb30 pumps with success, maybe see if you can tighten up the bolts, ideally it should be removed and resealed.

or buy the pump that fits

RB30 pumps are definitely different to RB25 pumps. Very similar but the RB30 doesnt have the elongated hole for the small bolt. I got around this by drilling & tapping a thread in the block to line up with the RB30 water pump. If you pull it all apart & have access to a tap & die kit, I recommend it. Also, not sure of importance, but 1 water pump I got had bigger impellers & less of them so I swapped it for a different brand which matched 25 pump impeller exactly...

Sure dude?

They're the same part number listing. Perhaps they're different for series 2 RB25's.

This is CORRECT .. They are all different engines so they cant all be the same .. There is a hole which he stated was on the pump but there was no hole on the block ! Should i use a genuine gaskit ? Or that loctite stuff .. ? I just checked today and i'm not gettin pressure in my hose .. I changed thermostat and all the hoses , genuine nismo radiator cap and coolant and still isn't getting pressue in line .. I think the pump has failed as today i saw my temp rise to 145*c which i didn't see straight away so i think i've just f**ked my motor !

[Kane_R32]

WP898 correct?

I too work at a parts store and have seen these go out for rb20/rb25 only to have them returned because of the one bolt hole not lining up.

I'd suggest genuine if another aftermarket one cant be sourced.

prob done head gasket or f*ked the head cause thats mighty HOT!!!!!

[Dorigecko]

That's it kane. TF898 would be truflow p/n, but industry number still the same.

we don't get much call for RB25 water pumps out in the sticks but my listings all say 898 is correct and 890 is rb26dett.

better brands do make a difference. difference between nu-line pulleys and gates pulleys. same number - different size sometimes. aftermarket will never be 100% exact, but if it doesn't fit, it doesn't fit.

glenn, if it doesn't turn over, then yeah.. sorry.. you've f**ked it.

Stop spending money when you don't know what the issue is. go through your entire system and rule out EVERYTHING, if not get a mechanic to look at it. and stop driving it!
