Bp swap overheating

[Nerd Racing]

I've got a civic radiator with a 14" slim fan and a 180 degree thermostat in my Protege (4wd BP swapped) and it cools it adequately enough.

Your rad might just be clogged. A new one cured my Festy's overheatig problem.

I was thinking about that too. I'll be doing what I can to it friday before I head out for 4thstiva

well a side from some scale knocked loose and making the coolant merky brown. I would say the fan switch is faulty. I would go ahead and hook up a toggle switch for now. If you see it climbing to half way just turn the fan on for a bit and drop the temp down. It should be ok on the highway, you should only need the fan in town traffic. Or just unplug the fan switch and let it run till you get there. Don't pull the rad or thermostat till we get a look at it. Smedley's BP swap car was doing the same thing when I looked at it.

I'm just gonna run with it unplugged for now. I'm gonna drain the dirty coolant and put new in tomorrow and drive it around a bit. I'll leave the rest for all you "pros" to check out at the meet!

Drained old coolant and installed new. Also got a new radiator cap since the old one was pretty much dunzo. Verified that the fan actually does work when plugged in so hopefully I'll make it to 4thstiva tomorrow without a problem and get some real "doctors" to take a look at it!

I would check the temperature differences between the top and lower rad hoses and also the heater core to see if something is plugged or the t-stat isn't opening.

Uhh did you flush the coolant or just drain and fill?

I'm thinking the tstat may be bad but I'm probably wrong

Didn't do a full flush, just a drain and fill for now. I was mainly checking to make sure the radiator wasn't clogged. The crew at 4thstiva will be looking at it for me tomorrow.
It's weird because after I put new coolant in I was checking to see what's up with the rad. fan. As soon as I started the car the fan came on (it was plugged in) and stayed on until the car actually started to get hot, then it cut off. So then I unplugged it at the temp. sensor and it still didn't come back on

That is weird, there must be an epademic lots of people are having fan trouble lately.

I would burp the system via the sensor in the therm housing. Keep it finger tight and when you get to temp loosen very slowly to let it dribble out. A lot of high power srt-4 engines recently have been messed up because of this oversight.

How did this turn out and what was the culprit?

Only thing I did before the meet was drain and refill rad. fluid.....did great on the way to the meet and back (and I took the long way both times). It might just be the fact that I get super worried about my cars after all the problems I've had. I think I still need to keep an eye on it and go from there.

^^ Did you replace that radiator cap too?

Oh yeah, did that too! Got one of the sweet ones like you have Mark

[Zanzer]

^^ Cool deal! (pun intended LOL)

Hopefully that'll have you all fixed up until we can flush the system properly :thumbup:
