Parked mine up for the winter having done around 10,000 miles in it last year and time to sort some niggles ready for when she comes out again in the spring time.

 

I had a Water system issue with the car last year, it was forcing Water out of a little heater pipe join right against the bulk head, right at the top behind the engine. I replaced the hose and the metal joining piece and no more water was coming out of there and I continued to use the car.

 

The car however did still always smell hot after that and did always smell a bit of burning coolant at the end of the journey although the temp goes up and down as it should and always has done. What I found is that the Water level seems to drop if I fill the rad right up until I can see it but then its almost like it possibly finds a level which is out of site when opening the rad but seems to lose alot less if any at all at that point. I'm not sure if I should be filling it right up to the rad or not. I suspect that if the level shouldnt be right to the top of the rad then maybe I have been causing the problem all along by over filling it and then it over pressurises and spits it out of a weak point. Alternatively should I be filling the rad right up in which case the car has got a problem somewhere?

 

Someone did mention something to me during the year about some sort of Water bypass system and said that standard plumbing on the car wasnt good and is a common fault and there is an aftermarket system that is worth changing to. Is this the case?

Superb thanks very much. Everyones so helpful on here. Must admit I was a stingy git and didnt join last year because I didnt think I was going to keep the car but I am keeping the car and I am going to join up this year.

It’ll certainly be £20 well spent Scott. [emoji106] For me, if it wasn’t for this club, I would most definitely not still have a 300zx!

I always seem to lose a bit of coolant with no signs of how, hopefully a rad cap will sort it!
