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

if thermo is registering low, then oil will be warm..

If the thermostat has failed and the coolant temperature gauge is working fine, then it shows that your coolant temperature is low. Low coolant temperature that is circulating through the radiator, will remove heat from the engine block, lowering the temperature of the block and the engine oil.

i have the same problem with my 98 vti-r, the mechanic changed my thermostat with a genuine honda one, but it still does the exact same thing could it be a different problem?, i went back to the mechanic and he told me i might need a different type of thermostat, one that opens only a small bit at boiling point, he told me. is this a good idea?

anyone know??

[rmalov]

could it be my temperature sensor or anything else??

Check the temperature sensor if you have already installed a new Honda thermostat.

I'm glad I ended up reading this thread. The first time I saw it I just overlooked it.

Today, I went to Astoria Honda to get a new Thermostat for $54.95 (including the gasket). The Service centre quoted $149 and 2 hours with my car to replace it...apparently it needed to fully cool down. Screw that!

I took it to my local mechanic (a good one) and he said he'd do it for $20 in 20 minutes. True to his word, 20 minutes later I drove away with my car feeling totally smoother.

woot!

I was just wondering would this faulty thermostat influence the bad fuel economy? Because my '98 model dc2 has the same faulty thermostat problem and I still haven't got around to gain my fuel economy up.

My fuel economy was pretty average. I was babying it about (as it wouldn't warm up) and getting about 11ltr/100km. Now that it's fixed I drive normally with the occasional boot in and I get 9-10ltr/100km.

So I'd say yeah, it could cause economy problems.

screwed thermo caused my car to run rich(er) and just run crap in general. didnt feel strong at all ( B18c7) and it took a couple of motorway trips to workout what was wrong.

If your temp DROPS on a long drive then change the thermo asap !

I've reset my ECU following Big'O's DIY and i finally see my temp go up a bit, but it still drops slowly when i run at 70km/h. So i guess i'm changing it no matter what. I bought the thermostat + gasket for $63 at Essendon Honda Parts store. Just one more question, what coolant should I use? original Honda coolants or any other coolants available?

[T-onedc2]

Only use Honda coolant is what I've heard many times.
