car heating up too fast?

[paps02]

from cold starts it takes my car maybe 2 or 3 minutes MAX of driving to warm up... but when i compare this to my brothers delsol it takes about 5-10 minutes of driving to heat up.

so how long should it take for my car to heat up and how long does it take your h22 to heat up?? is mine heating too fast and possibly have a head gasket issue???

cheers

but does it overheat?

if not, then dont worry about it

[Zinyo]

if its doesnt overheat (as in no more than half way on the meter)...i dont think there's a problem with it. My dc5r does the same thing, when i do drive without warming up the car, the temp goes up to normal temperature quite quickly (3mins or so). But yeh, just warm up the engine before hand...

[outatime]

it's probably because your car uses thinner engine oil viscosity than your brother's..

its probably your brothers thrmostat being f*cked most cars should only take 3-5 min if everything i working fine

guys, we're not living in the 60's or 70's anymore, nor do we have rotaries. even if its -20 degrees out there, only let it idle for 15 - 20 seconds before driving off. best way to warm up a car is to drive it gently.

an idling engine is bad in heaps of ways. fuel is not completely burnt so it condenses in drops on the cylinder walls. the fuel washes the oil off the walls and causes unneccesary wear. unburnt fuel can also flow down the walls into the sump which can contaminate the oil. when idling, temperature of spark plugs drop which leads to dirty plugs which reduces the km u get out of a tank. lastly, longer u keep idling there, the longer the water droplets will remain in ur exhaust on a cold morning. water in exhaust leads to rust, which is kinda obviously bad...

from another thread, here is what i posted


warming a car up is the worse thing you can do, for a few reasons, if you have a search youll find them all, but here is a quick run down

1. idling causes fuel wash. the excess fuel in the cylinder not being burnt literally washes the oil off the cylinder walls, removing lubrication
2. emissions control devices, specifically the catalytic convertor work when heated up. idling the car isnt going to heat it up, so for the 5 minutes its warming up all the toxic nastys are spewing out the exhaust.
3. youre wasting fuel warming up. the ecu automatically supplies more fuel when cold to prevent stalling. thus wasting petrol (and causing fuel wash)
4. you sit there for 5 mins warming the engine up thinking youre sweet, then pull out and give it a hit thinking its all fine. well its not. where does the power go through before it hits the wheels? the gearbox/rest of the drivetrain. you hit it, and your 'box is cold still and you cause wear on the drivetrain.


thats a basic run down on why its not necessary. simply get in, start the car up and drive away, taking it easy until the temp reaches operating temperature, that way everything warms up at the same time and you dont damage anything

How revs do you go up to on cold ?

[DLO01]

2-3 mins in fine. :thumbsup:

How revs do you go up to on cold ?

try to keep ur shifts at 3,000rpm

[paps02]

my gauge sits just a little bit over half way. but i think its broken..

because on the dyno the tuner told me my engine was running at like 94deg and he had to let it cool down after only a few pulls... he was worried it might be a head gasket and when i told him how quickly it warmed up he thought yep probably gasket. but he changed something in the computer settings and got it running at about 84-86 which i think is normal??

mines takes longer than 10 minutes to get a quarter dc2

you need a new thermostat mate.

and george... im sure its nothing major. might just be the heat sensor..
possibly thermostat.

[paps02]

just that when i compared it to niko's delsol mine seems lightning fast. but his thermo must be fkd also..

how long is urs taking now with the new thermostat??? not that you can drive and test it out lol...

see u tonight?

[VTECMACHINE]

It very much depends on outside temperature. You are talking about Water temps. It's a different car, and radiators are different etc... If it's not overheating... it's perfectly fine. If it's overheating... then your thermo might be gone.

But seriously... no need to worry about it, if your car is not overheating.

[CRXDEL501]

mine takes 3-5 mins.
it has been tested dont worry lol
yeah tonight is alrightt
