Hi all,

I have a major problem (i think) with the car. Since the last service (2 fridays ago), the car has been running fine. But then today when I was coming back from a very long drive (180klms), I noticed that the temp needle was going up and then down a bit. I thought this was just normal, so I didnt bother with anything. But then later tonite, after I came back from my bros house (about 5 mins away), the needle went right up.

My dad and I opened the hood, and there was a horrible smell. We knew that it was due to leaking coolant or lack of coolant. The water pump looks to be intact, but below the engine, there was a lot of liquid. That means the coolant is leaking froms somewhere there. We have checked the pipes as well, everything seems to be ok. I dont know where else to look.

Do you guys know what I can look out for as the main culprits for the leakage? We have filled up the coolant reservoir and the radiator, with a mix of coolant and water. But its still leaking. I am thinking of taking it to GTAutos for them to have a look at it, but I would appreciate any advise/pointers that you guys can give me.

Thanks in advance.

coolant can come from

rear: turbo feed pipe that is behind the head, and is fed from the rear of the plenum. heater hoses

side: oil cooler, heater feed hoses, feed from thermo housing to the plenum. turbo water feed @ turbo

front: radiator hoses.

This could mean that your water pump needs replacing. Happened to my mates R33 and was told that there is a small hole that will leak water/coolant when your water pump has had it, nissan mae it this way as a warning sign. You can see it if you look hard from memory. He was also told that once it starts leaking it should be changed fairly soon as it won't last much longer.

If it is your water pump then arrange to get your timing belt changed at the same time if it's close to needing it.

Good luck with your vehicle man

Thanks for the info bud - but I changed the water pump 5 months ago (the timing belt and all were also changed). I do see something that looks like a crack, but hte pump is completely dry on the outside - nevertheless, I will get Wayne and Jarrod to have a look at it again.

passenger side in the middle ???

sounds like turbo's water feed :blush: bit fiddly to get to though

can be feed or return, banjo bolts at return at block, and the turbo for feed and return .. feed comes from a rubber hose from behind the head

First, if it is coming from the "middle" of your motor but cannot trace it back to a point source like a coolant hose, then it is likely your head gasket. Second, change your oil to make sure it does not look like chocolate milk. If it looks like chocolate milk, you have problems. It is either a cracked head or blown head gasket.

Thanks for the heads up guys.

Craved: Its on the drivers side (towards the middle) - so im guessing its got nothing to do with the turbo.

Darius: i have checked the oil - it seems to be ok. I had the car serviced just 2 fridays ago by RE Customs.

i might check with them to see if they noticed anything abnormal about the car when they did the service.

Update: Ok, we have found the culprit. Its one of the Cylinder wall plugs. Seems that the bastard has rusted, due to the improper coolant mix being used. Uh!!!!! Thank god its not a major problem like a blown gasket, but I believe that the repair work will take a long time!

Well, I have to get him to check it on monday. I could only see one that was rusted beyond recognition. Hopefully get the whole thing replaced. The waterpump is fine from what i can see.

Just wondering, how long would it take to replace these welsh plugs? Do they have to extract the whole engine? I know the have to flush out the coolant before they do anything, but if they have to remove the whole engine - then im gonna be charged shit loads.

    • The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.
    • When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.
    • Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.
    • This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.
    • Either the bearing has been installed backwards OR the gearbox input shaft bearing is loosey goosey.   When in doubt, just put in a Samsonas in.
