Coolant Leak?

[_MRR33]

Hey,

Well, here's the problem I'm having with my R33 GTST at the moment, I had coolant spilling out of the overfill tank for a couple of days, however the coolant levels and running temp of the car was fine, it wasn't overheating at all just normal running temp.

I however, took the car to a radiator specialist and spoke to someone there about it, he said that the radiator cap needed replacing (even though I replaced it about 4-5mts ago). He also said that it wasn't sealing properly.

He also went on to say, best bet is to get a 16 pound radiator cap or replace it with a genuine Nissan one, which I will do tomorrow.

Nissan sell them for $21 and a 16 pound one from Autobarn is $50.

Anyhow, while the car was parked at work today there was a puddle of coolant on the passenger side of the car, it was really weird being dark I couldn't see where it was leaking from so I toped it up drove it home and it was alright.

Though, I'll have to have a look at it tomorrow when there's some more light, just wanted people advice/help on what things I should look out for, thanks.

Stock cap. High pressure radiator caps should NOT be used on a factory plastic radiator.

In the event there is too much pressure, rather than the cap blow, it will shatter your radiator to pieces and cause a mighty mess

Factory all the way

Yeah, I was never planning to buy the 16 pound one, just the genuine Nissan one.

Do you think that could be the only problem though? What else should I check for tomorrow?

Thanks R31Nismoid,

If the overflow isnt leaking, and the radiator cap is new.

You have a crack in the radiator somewhere i would imagine, or turbo line possibly as you said passenger side.

Maybe a leaky plug somewhere around a water gallery.

Things like that can be hard to find as the water runs along parts, so it could be coming from the other side of the car, best to trace the leak if the cap doesnt fix it.

The radiator cap lip is plastic isnt it? So it cant be that.

Here's the update..

I went and picked up a genuine Nissan cap this morning and put it on, started the car and noticed that there is coolant dripping from underneath the car, around the area of the oil sump and fan belts, can't seem to pin point where it is coming from though, any ideas?

sounds like the water pump bearings

check under the pump behind the pulley, there is a small hole there, if from there you need to replace your pump
