Hey guys,

weirdest thing Happened today!

I was driving for more than an hour and needed to fill up, so i stopped into the servo topped up and went to start the car and *doh*

checked my PFC and it said my engine temp was 95C???? (Normal temp is 80C, ignition switched to "on", the car was not started).

that was the only thing that i could see on my HC that was out of the ordinary?

i left it for 5 mins and tried again and it started! so i nursed her home, keeping an eye on the temp which didnt go over 83 but even that is weird as its never gone over 80?

when i got home is was gurgling like crazy? and i could feel air bubbles passing through the top radiator hose?

Would my car not start because of its temp? any ideas guys?

cheers

Radiator could be slightly low. The 95 is normal if the car is turned off as the water does not cycle so you get what's called heat soak. The temps will rise around 10 deg and then stabilise. The gurgling in the top hose is due to the water boiling in the top section of the system.

Start by topping up the system, bleed it via the bleeder and replace the radiator cap as they are usually fubar and it's the last thing people replace on their car as most people don't have the equipment to test them.

Also, top up the expansion tank on the side. slightly overfill it so if the system needs to recover any more fluid, it can grab it from here. If the radiator is low but the expansion tank is full then it is likely the cap is stuffed. If the radiator is low but the expansion tank is empty then it could be a leak somewhere or headgasket etc.

You don;t have to use coolant for topping up, water works better but it does not have any corrosion inhibitor so the system will rust and wear if you dilute it too much.

I always advise using the heavy duty Tectaloy Radiator flush in the black bottle, completely drain the system and refill with plain or distilled water. Use Redline Water Wetter as a corrosion inhibitor. Water Wetter lowers the surface tension of water by reducing the amount of cavitation, thus creating a greater surface area for the water to absorb heat. This means you will also reduce engine temps.

thanks alot man,

i checked my over flow tank and it was empty :P so i topped it up. my actual radiator was a level though? its pretty dirtty though it well needs a flush.

where is the bleed valve the rid the air though?

Could my coolant problem be related to why my car didnt start?

      Questions on potential new purchase

      Could be. Could also be that they sit around broken more. To be fair, you almost never see one driving around. I see more R chassis GTRs than the Renault ones.

      Yeah. Nah. This is why I said My bold for my double emphasis. We're not talking about cars tuned to the edge of det here. We're talking about normal cars. Flame propagation speed and the amount of energy required to ignite the fuel are not significant factors when running at 1500-4000 rpm, and medium to light loads, like nearly every car on the road (except twin cab utes which are driven at 6k and 100% load all the time). There is no shortage of ignition energy available in any petrol engine. If there was, we'd all be in deep shit. The calorific value, on a volume basis, is significantly different, between 98 and 91, and that turns up immediately in consumption numbers. You can see the signal easily if you control for the other variables well enough, and/or collect enough stats. As to not seeing any benefit - we had a couple of EF and EL Falcons in the company fleet back in the late 90s and early 2000s. The EEC IV ECU in those things was particularly good at adding in timing as soon as knock headroom improved, which typically came from putting in some 95 or 98. The responsiveness and power improved noticeably, and the fuel consumption dropped considerably, just from going to 95. Less delta from there to 98 - almost not noticeable, compared to the big differences seen between 91 and 95. Way back in the day, when supermarkets first started selling fuel from their own stations, I did thousands of km in FNQ in a small Toyota. I can't remember if it was a Starlet or an early Yaris. Anyway - the supermarket servos were bringing in cheap fuel from Indonesia, and the other servos were still using locally refined gear. The fuel consumption was typically at least 5%, often as much as 8% worse on the Indo shit, presumably because they had a lot more oxygenated component in the brew, and were probably barely meeting the octane spec. Around the same time or maybe a bit later (like 25 years ago), I could tell the difference between Shell 98 and BP 98, and typically preferred to only use Shell then because the Skyline ran so much better on it. Years later I found the realtionship between them had swapped, as a consequence of yet more refinery closures. So I've only used BP 98 since. Although, I must say that I could not fault the odd tank of United 98 that I've run. It's probably the same stuff. It is also very important to remember that these findings are often dependent on region. With most of the refineries in Oz now dead, there's less variability in local stuff, and he majority of our fuels are not even refined here any more anyway. It probably depends more on which SE Asian refinery is currently cheapest to operate.

      You don't have an R34 service manual for the body do you? Have found plenty for the engine and drivetrain but nothing else

      Tein Circuit Master- rebuild worth it?

      By MBS206 · Posted

      If they can dyno them, get them dyno'd, make sure they're not leaking, and if they look okay on the dyno and are performing relatively well, put them in the car.   If they're leaking oil etc, and you feel so inclined, open them up yourself and see what you can do to fix it. The main thing you're trying to do is replace the parts that perish, like seals. You're not attempting to change the valving. You might even be able to find somewhere that has the Tein parts/rebuild kit if you dig hard.

      Can you also make sure the invoices on the box (And none exist in the boxes) are below our import duty limits... I jest, there's nothing I need to actually purchase and order in. (Unless you can find me a rear diff carrier, brand new, for stupidly cheap, that is for a Toyota Landcruiser, HZJ105R GXL, 2000 year model...)
