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!

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.

    • For these last 7 years of ownership, I've always had to use a small scissor jack under one of the front tow hooks to raise the front just enough so my low-profile jack fits under to reach my subframe jack point. I'm beginning to get annoyed of always having to do this. Are there any lower low-profile jacks that fit under the gtr lip on a dropped car?
    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
