stud through heat exchanger- question

[Tyloooor]

put a stud through my heat exchanger on Sunday. My overheat light came on and I shut the sled right off.

Let my sled sit for 3 to 5 min to cool down- started it-no temp light came on, but towed it home and it leaked the whole way and is still leaking out

how will I know if my head gasket is finished or not?

Compression test, milky oil.

I'm in the process of taking my engine out because a stud ripped exchanger.

I don't have a 10mm adapter for my tester and I want to do a complete look over of the engine before I put everything back together. It will also be easier to weld when everything is out.

I was reading that you didn't need to pull the motor to get the heat exchanger out- just the subframe and the side piece behind the oil tank

I have a local welding shop that's going to weld it up for me. All i need to do is get the skid, track and drive shaft out

just read a lot of threads, about the head gasket blowing and warping the head

Put a huge gash in the front on my old A/C Firecat after a stud ripped the track.
Cleaned up the jagged aluminum pieces with a Dremel, isopropanol alcohol wipe down then used JB Weld in thin layers to fill the gap.
Didn't even remove from sled.
Took 2 days but set up solid & held for 2 more seasons with no problems.

You will be ok I did sane thing last year no problems... now if us ran it till it sits itself then you got problems like I have now

got her back together last night and took her for a little test ride....seems good so far, but will be taking her for a good ride tonight

Did you get all the air out & pressure test it as well before riding?

 

[Tyloooor]

I had it pressure tested at the welding shop

I do believe we got all the air out of it....was a bitch and had to add a lot of coolant- put the sled on little incline , without the rad cap and let it idle to try and get all the air out.

Before I put the skid in, I cracked the plug in tunnel exchanger while I was filling the anti-freeze to insure it was getting coolant.

after sled warmed up- I check both rads- no leaks and they were getting warm

Is there anything else I should check? I don't have a 4-stroke compression tester

You need a bleed down, not compression test. If your confident it didn't get HOT, (you mentioned it leaked on the tow) you "might be ok. It's worth a good run and after a couple of km's or miles you'll know, warning lights or stop and check your overflow. I have a feeling if your sled was that wet, you'll be ok. IMO

 

[Tyloooor]

took it out for 80 mile ride last night.....everything seemed fine....

 

[Tyloooor]

what's the best way to "bleed the system"?

 

[1975FA]

My nytro came with a leaking head gasket when I bought it. What a deal. It would sit and idle all day long and not push out antifreeze, but as soon as I went down the trail she would start pushing it out the overflow. I say take a 10 mile run with your unit and see what happens. If it's pushing antifreeze out it's head gasket time.

 

[Tyloooor]

I went 80 kms or 49 miles last night....no light came on, nor did it puke any coolant....did some tight trails, fast trails, and lakes

I hope it's fine...

 

[canoehead]

I'd say after 80 km's and every things normal you lucked out! The best way to bleed is park the sled in a slight nose up angle, leave the rad cap off and run it until you see circulation for a couple of minutes. Then you'll see if more coolant is required.
