I drive a 2003 Hond Civic, bought used at 110k, Nearly 180k miles now. Radiator replaced at 120k or so.

Sixty-thousand miles accumulated, a problem occurs. Throughout last winter, cabin heat would mot work; until reaching speeds of 40-45 mph, and only after driving for 30 minites or so. Coolant check, oil change, check. Continue without much problem.

I begin to notice that when I turn my cabin temp to hot, regardless of turning air-flow on, my temp gague on my dash rockets up to unsustainable levels.

My questionis whether or not I oughta investigate the thermostat, the thermoswitch for the the belt fan, should I check my water pump (i also see a greater effect ofthe same described phenomenon once going uphill for a prolonged period), do i just have an air pocket in my air system? I have spiders in my vents too. what should i do?

I have some expendable monies in the range of less than 1k.

Did you even attempt to let the car warm up, before turning the heat on?

Umm dude... cabin heating uses the heat of the engine... of course it barely works until your engine is at operating temperature wich takes about 15-30 minutes of driving...

Got lots of experience with that engine. This is screaming head gasket to me. They always end up failing when the mileage gets up their. Compression/leakdown test before you put any money into that thing. You’ve probably warped the head due to the xcees heat so you could potentially not be able to resurface the head and slap a new gasket on.

You got issues coming m8. Go on 7thgencivic and research. It’s dead now but a wealth of knowledge is still available (mostly)

I've owned many cars in my lifetime (51 to be exact) and I've owned some good ones like a 1990 Eagle Talon TSI AWD turbo that I modified to make 586 awhp, multiple Cadillacs, I even built a 92 Dodge Colt hatch with a 4g63t swap that ran 11s, but this Civic has been my favorite because it's reliable, easy to build and work on, and nobody expects it to be as fast as it is. I'm upset

OP here

This took a really brash turn.

What im saying is that the cabin heat used to run just fine, and now it doesnt.

Not like I need it now. But the engine thermostat reads hot after 2 minutes of switching the cabin heat knob to hot.

Not to derail the thread but I have a smilar problem in my 1988 Honda Prelude, 3G

Has quite the mileage on it but it still runs well. She's my baby & I'm trying to fix her up.

The transmission started going out & I thought it was one, already had the engine replaced. Turned out it just needed fluid.. Japanese & their tiny hands man, took my friends dad 20m to find the trans fluid to fill it up.

Thing is the car is overheating, especially if it idles a while. I can't drive it more than 30m before the engine temp skyrocets. I may need a new radiator but I don't think that's it.

Fairly vague with my assessment here but any advice appreciated, I love the crap out of Third Gen's. Goal is to keep mine as a parts car & find one with 4WS
