Tempreture is HOT?

[pushead]

was driving around today then suddenly the tempreture dial is really close to "H".. What factors can cause the tempreture to rise so fast and high? what should i check besides the coolant and how often should i top up the coolant?

Thanks.

You shouldn't really need to have to top up the coolant, have you changed you coolant recently??. Make sure your coolant color is okay and there are no leaks in the system, make sure the overflow bottle is topped up.

Thanks dude, I have a closer look, not sure though, might have aleak.

I topped up the coolant in the white bottle as well as the alternator last night, this morning all the coolant dried up

topped it up again, look under the car and it is leaking!!!!

Helpp guys, anyway to stop the leak? what causes coolant to leak??

[predator]

bad bad bad!!

is it from the radiator? or from the block?? If it is from the block it could be a busted head gasket and its going to cost big $$$ If you continue to drive it you will warp or crack the head resulting in even bigger $$$

If you are lucky.. it is just busted radiator, or split radiator hose. Not that you should be driving it in this condition, but pop the bonnet.. you should see steam shooting out from somewhere - which will narrow it down. If you are lucky it will just be a hose.

My recommendation is not to drive the car at all until you can work out the problem. It most likely is quite serious.

Temperature problems can be FATAL to an engine..especially a modern engine.

got your PM pred and thankyou for your help... damn, now im shitting my pants, don't know where exactly it is leaking.. i looked under the car and it has the black shield covering under it so i couldn't tell whether it is the hose, or the block but it is defintely 100% coolant(green liquid). Just went down to the local mobil petrol station and brought some radiator stop leak treatment bottle.. going to add it and hope it helps..

Check the hoses, or remove the cover. Just follow the hoses down to where they end like the bottom one see if there is any fluid leaking. Best Bet is jack it up and take the cover off. I could be the water pump (how many k's) some of them go early before 100k. Or could be a cracked radiator as suggested above. (which is alot less common).

I'll put money on it being your water pump. Check the water pump, there is an inspection hole that will allow coolant to slowly leak when the pump seals shit themselves (telling you it's time to replace the pump). With the undertray in place you'll never be able to pin-point the source of the leak. The tray comes off easily.

If the pump is the cause you're up for a new one, & you may as well replace the timing belt while you're there. You need to take the same bits off - so why do it twice?

New pump from Nissan (same as RB30 VL pump) - $90-100

Timing belt - $80-90

Labour - ~$150 (dunno' exactly on this one?)

I very much doubt it'll be a major problem, so don't stress too much

Alternator - coolant? WTF! Coolant & the alternator don't mix well dude!

???? so you put water instead of coolant in the alternator? i followed a black hose which goes to a white bottle(the backup bottle) which labels coolant.

Checkout the attached Picture:

yah man that right. it's to the overflow bottle thats what it is called. The thin black hose if for the overflow bottle. There are big hoses coming off the radiator the top and bottom to the engine. check those for leaks.

[Guest RedLineGTR]

Any success with the leaks??

[pushead]

at work today dude will check tomorrow and let you know..

cheers and thanks for your help RedlineGTR..

[Ender]

you lucky bastard with the temp that hot ur lucky nothing blew

mine ran hot once and blew the seals on the plastic radiator end tanks - goodbye radiator

the water pump is a c*** to get off cos of the crank pulley bolt. you will more than likely need a rattle gun to get this off

the water pump may not be dead, it my just be the seal, in which case pull the pump off, put new sealant around it (doesnt use a gasket) and put it back together

you can drive around with a leak BUT make sure u keep the system topped up

if it starts sucking air or depressurises it will overheat again and u may not be so lucky

take it to a mechanic and there are pressure tests you can do on the radiator so check for a leak/crack. you can also run a test to see if there are exh gases in the system (leaking head gasket) so you will be able to pin-point the problem

just finally, cooling systems are ****s to work on and fix, if youre going to repair it make sure u do it right cos its the kind of thing which if not done properly will cause alot of headaches

I would say this is invaluable advice.

Our pumps are cheap which is good.

You want to do pump, timing and accessories belts at once to save labour.

$150 for labour is damn cheap though.

I paid $350ish (think it was 350? Certainly under 400) for a new genuine Nissan w/pump & timing belt. Both installed. Thanks Vince (Rigoli).

I didn't want to take any chances so I got them both done. That way I knew they were new

Thanks for your detailed info dude.. really needed it...yep. same as the RB30 VL pump.. what hole are you refering to which you can tell the water pump shit itself?.. i couldn't seem to find it.. is it near the fan belt?
