taking a while to warm up

[bennjamin]

Could also be a coolant problem as if you don't get the right mix the coolant can affect the temp of the car's water temp.

Rem to change the coolant with some OEM stuff after then themostat is replaced. I had this problem before also.

The premixed Honda coolant (comes in 5-6 litre containers , there are two types , green mix and blue mix...) works out great

btw... i use Toyota coolant in my honda so i shouldn't talk. Its Red and its got an extra chemical called Benze.... something that protects the car.

Definetly your thermostat:

Air is heated by passing through the radiator, if your thermostat is stuck & not letting enough hot water to pass through radiator, then you wont be getting much hot air inside the car. If your thermostat was running correctly, there would be a large amount of hot coolant in the radiator, the air passing through it will also be a lot warmer...

Hopefully this answers your questions...

not 100% sure on that explanation mate. if the thermostat is stuck open, you are getting coolant circulating through the radiator ALL the time, ie at startup when you dont want it to be.
in fact, the problem is that there is a large amount of COOL coolant in the radiator, when in fact you want the coolant to be circulating around the block.

the reason that the heater does not work when the car is cold is that the coolant is yet to circulate through the radiator, and thus no heat is being drawn from it

hmz my EG takes quite a long time to warm up (more than 3 times longer than the Euro), but the thermistat seems to be working ok. The warmed-up temperature is at the normal position, just under the half way mark.

If the thermistat was stuck open, wouldnt the temp sit lower than normal when warmed up?

its possible but that wouldnt be a good way to diagnose it.
a better way would be to drive on the freeway once you have reached normal temp. if the temp drops once you get cruising at 100km/h or so, its a good indicator that the thermostsat is stuck open, because at these speeds there is enough airflow over the engine itself that thermostat should be closed, and thus no coolant circulating the radiator

[EuroDude]

I see. Well if mine is indeed stuck open, at least it didnt get stuck closed this time lol... that wasn't fun at all.

[Mr_will]

haha damn right, stuck open is far better.
changing thermostat is pretty easy, and i think someone here has a B series one for sale..DIY yo.

yeh ive already replace it myself once, very easy to do.

If its faulty again then this is the second time in 250,000km.
Is it just me or do EG's have Thermostat, Distributor, and CV boot (RHS torn) issues?

you couldn't be more correct! LOL

My gf’s em1 also takes aaaagggeees to heat up and it never reaches half way, the most is 1/3, is this also a thermostat problem?

2 pages and 100 threads later..

Just unhook your radiator hose and pump water through it.. if water gets plums through then it must be stuck open..

its it plums back,.. then try again with engine started... then if it plums back again.. your thermo is fine.. remove it and change collant..

else replace both collant and thermo

Problem solved

I am running Redline Water-Wetter (with water) as my coolant.. and when i initially changed from (OEM?) the original coolant, there was a slight drop in the 'operating temp' as indicated by my temp guage.. however I made this change to Water-Wetter before my B16 swap.

and mine takes AGES to warm up and if warm and cruising on the open-road, the temp guage will continue to drop.. however I did notice this started just before winter.. it was a noticable difference so I am assuming it's the thermostat.. but just wondering how say watter wetter may affect the thermostat's functionality.
