Resolved GVR-4 - Another coolant boiling thread

[DarkKnight86]

So I'm having this problem with my coolant boiling in the overflow but my car temp gauge is staying in the middle. When I log the data using ecmlink my temps go from 180 then 200-223. The highest temp I seen was 226. I have done a compression test and have 160 across the board, replaced my head gasket twice and head l19 head botls are tq'd to 100 lbs, replaced the thermostat twice, changed from a 90 style water neck back to the coolant neck with the coolant temp sensor on top. When I burped the coolant system I notice the coolant isn't circulating, rather just rises. I just went from a 16g to hy35 turbo. My water pipe isn't wrapped, I am using a scircco radiator from amazon. I have searched countless of overheating threads on the form, galantvr4.org, dsmtalk and googled. I'm going to replace the water pump in the morning and if that doesn't work I will get my spare head resurfaced and redo the head gasket again.

I'm thinking it could be the radiator I'm using from amazon. My water pump is a gates water pump, current head gasket is a fel pro that I copper sprayed on both sides. At this point I'm lost and probably put the car back on jackstands.

What about the thermostat .....What is the rating of it and do you know for sure it is opening.

Well after getting the head back from the machine shop and putting a new head gasket as well. I'm still pushing coolant into the reservoir. I will be getting new studs, doing the head gasket again. I did a coolant test and the fluid changed from blue to green. I bled the coolant for an hr and temps climbed up to 226, coolant was bubbling in the funnel as well.

I wouldn’t do that. You don’t want to throw parts at it. Diagnose and find where it’s getting air from. It could be a cracked block for all you know.

Have you checked the passages on the block and radiator to see if any of those are not blocked? A blocked rad wont help so narrow it down some more

The fans should come on at operating temperature.

This is the radiator I bought:

So far this is what I've done.
- headgasket
- water pump
-3 180* thermostats: tested all in boiling water and they opened up at 180 degrees
- 3 radiator caps: 13psi and 16psi cap
- using 50/50 prestone coolant
- I got a 90 dsm style water neck from extreme psi

My fans cut on right as temps hit 180 and stay on. The block I am using was originally in my car before I pulled it due to a oil leak from the front case gasket. The last 2 things I am going to try before I say screw it and just rebuild my spare block is another radiator and get a new set of L19 studs. I never had a problem before with coolant and I'm stumped at this point.

Fixed my issue, coolant tempts are holding between 174-190. It was the radiator I was using from amazon. I had a old mishimoto civic radiator laying around. I just thought maybe I should try it. After bleeding the coolant and I let it idle for over a n hour in the garage and temps was holding. I then took it our and cruised for about 45 minutes and no more boiling coolant in the reservoir. Logging on ecmlink temps never went over 196. All this time it was the radiator hahaha. After I spent the cash on getting my spare heard resurfaced, 3 head gasket, 3 thermostats, 3 radiator caps, water pump, and multiple times doing the timing belt. I finally get to sleep at night and not think what could my issue be.

Arh see so my suggestion on the rad was right at the end! If all else fails you have to check components and i would of done this after the leak down test if that came back as fine.

We are glad its resolved and now know you can buy a proper radiator (no amazon crap)
