94 Vti-R running cool (not in a good way)

[trentd]

They sit low, hondas are good with there water temps.
if it is sitting very low then it could be numerous things such as;
thermostat.
oil to thick.
and too much coolant.

otherwise if its sitting at least the third of the way up then you should be happy. because the furthur you stay away from that 'H' the better

Good call. Preferably it should sit between 2/3 and slightly less than 1/2 way.

Wow, i remember when this thread was in it's infancy. This thermo is a common problem for DC2 'tegs, so I'm not surprised its been active for so long.

Props to the DC integra! Its a cult classic!

Ahh man this was really helpful. I just bought my DC2 VTi-R and I was wondering why it took so ridiculously long to warm up on the move. Changed the thermostat and bada-bing! It works properly now! I'm really enjoying driving my first VTEC car!

[BONDAVILLE]

Ok you all know that vtec only works when the engine is at normal op temp. Thermostat is most likly coz (it's probly jammed shut) or stuck half way lol

Hey guys, would you recommend i change mine? Mine sits to the left of Cold for about 20-30 minutes... then after driving for ages, it'll go about 1/4-1/3 (on a hot day). My family members are saying "yeah dw it's fine, just an old car"... but my fuel efficiency is eating dick and i think something is wrong.

I think you should. That's not normal. It should sit just to the left of half way. 2 things i can think of which are side effects of this are:

1. certain things that require the engine to be at certain temperature will not work, eg VTEC
2. Engine components if not warmed to its optimal temperature may not expand as per normal which could increase wear and tear.

I have a GSi, so no VTEC. The main problem is just fuel economy... i'm not even getting 300km from a tank at the moment.

you pretty much answered your own question.

Lets put your situation into perspective.
You got 2 options.

1 - you leave it.....
You're forever thinking about why you've got a dick for fuel consumption, always a pin prick at the back of your mind digging away.

2 - you change it.......
you've gotten it off your chest and if it fixes your dick consumption problems. Excellent.
If it doesn't then it probably needed to be done anyway sooner or later. its done. move onto the next item in question. (if changing it didn't rectify the problem)

You make up your own mind.

Youve already laid it all out on the talbe.

now grow some balls and make a decision.

told mechanic about the temp gauge not going up and shit fuel economy. He said to do two more tanks and record the l/100kms. I got 11.5l/100km on the last tank. Is that shit for stock gsi? Current tanks almost empty and only done 250km

[dbzerk]

I had the same problem with my vti-r running always cool. I pulled out the thermostat only to discover that it was jammed open because the central guide pin was bent. Easy fix and cheap to do.. All should check this if yours always run cool! Ill try to get a pic of it up soon

[charliebrown]

Just refilled yesterday and got 12L/100km, my mechanic said anywhere between 12-14L/100km is acceptable for a car that old. And that replacing the thermostat carries other risks, often not worth it for a little bit better fuel economy.

Holy biiitch balls! Charliebrown just change the damn thing. Why is this even a question? Your engine is unable to get warm quick enough (and I bet once you start cruising your temp goes all the way back down) causing your engine to wear out faster than it normally should. It also costs barely anything. It's a bit fiddly to do but WHAT risks? If you do it yourself it'll be less than $50 (assuming you have to buy some el-cheapo tools considering you're so scared of doing anything) and you'll get your money back ASAP (at $1.30/L, you're paying around $4 more per 100km than everyone else).

Also, no offence to your mechanic, but you need a new one...

Not having a go at you (and I am trying to help you) but this is a no brainer. If you were in Sydney I'd change it for you myself. Good luck.................................
