Hey all. I've done a LS to GSR swap a couple of months ago and I've noticed that my coolant is leaking. For some reason though I can't seem to see where it is leaking. I can smell it burning however. I have to warm the car up for like 10 mins everyday before a drive and the temp needle stays at the "C." EVen after a 30 min drive, the needle still stays near the C and not at the quarter mark. Is it the thermostat? I'm guessing it could be the sending unit too. Also, my A/C isn't putting out cold air if this helps any.

Thanks in advance for any help.

Anyone?

 

I would say that you need a new thermostat for sure. It's very possible that the coolant could be leaking around the water pump, water pipe on the back of the block, head gasket, any coolant hose, radiator, etc. If it's not obvious where it's coming from, the best thing to do is have a clean surface like a piece of cardboard or something similar and put it under the car and check for drips. From there just trace the leak from that location and chances are you'll find it.
