bizzaro land coolant temps
 

the past week, my car has been trying to overheat when i am at a stop light. temps are chilly-chill all other times and it's been in the 30's F tempwise so it makes me laugh a little.

note that this is with the heater on.

normal driving temp is around 190F

stoplight for 2 minutes brings it to 220-225F (which I dont consider dangerous)

as soon as I roll away, it falls back down to 190.

it could be a dead fan or air bubbles or something, but since I haven't checked anything yet, i'm just posting because it's weirdly timed with cold weather.

pinhole leak?

cap leak?

thermostat stuck?

fans working?

Check to see if the fans are working first.

FWIW, my motor runs pretty hot all the time. Like 210-220 ish. I'm'a do a reroute one day and see if that changes.

I'm about to buy a swirl pot.

I'm about to buy a netti-pot.

I'm about to buy a tea pot.

I remember when you visited bizarro land air temps

yes, but that was a dumbass wiring error :)

Damn you for making me look up what that was. I'd managed to forget about Rick's nasal escapades... :barf:

you tube videos ftw!

peter pan coolant reroute wiring error?

Sounds like my car with broken fanz.

the true test will be friday when it's going to be 8° :(

My car has been stuck at like 200-210 highway. At stop lights 190-200. Without ducting or cover, a koyo 37mm, & stock fans. I'm going to have this race prep shop make me ducting so I can get the temps down a little lower.

This is relieving. I thought my car was running mad hot.

I'll tea-bag your netty-pot.

For over a year now I've been trying to figure out why my car over heated.. I never could find anything in the tune, the fans ran, I upgraded the rad, replaced the cap, the thermo, etc..

Same boat here, except I haven't replaced the rad yet.

both fans were on when I got home tonight. I didn't notice it get above 210 though. :dunno:

<burp>

but how did the air get in there if I haven't touched the system in months? did I <burp> my head gasket??

peak coolant temps in the datalog were 111C / 232F. hmm.

normal temps in the same log (driving) were 87-88C / 188-190F. doublehmm.

Small leak can cause air ingestion.

bringin it back alive:

so there was some serious missing coolant and I temporarily filled it up with water until I get a chance to flush the thing.

and I noticed a little dribble of water from the bottom of the radiator drain plug. I dont know if that's where it's coming from because it's the lowest point, but it's pretty minor I think.

next question: anyone know a good place to get an aluminum koyo radiator fixed up to patch leaks in northern virginia?

Anyone who can TIG should be able to patch it up.

I FOUND IT.

it isn't the radiator--technically. The drain plug failed. Not sure how, but it's plastic and I guess heat cycled or something. Or I overtightened it (hard on a philips head drain plug like that).

When I tried to pull it out to drain the rad, it just broke into pieces. I had to drill it out.

So I replaced it with a bolt and some silicone hose to make a compression gasket. Hopefully it wont leak now.

lame!

my drain plug leaks slowly, i really need to fix that shit.

#10 flange head bolt and some 10mm silicone hose about a half inch long.
