Ok so my buddy bought a turbo ls hatch stock ls turbo ok I noticed one day that the coolent resivoir was bubbling and over flowing doesn't happen during driving only when the car is parked and still running due to the turbo timer also noticed when it's running off the time the fan goes off so I started to look around a lil and also saw there is no thermostat and the radiator is filled only with water idk wat to think is it cause there's no thermo and only water and no fan wen parked lmk wat you guys think and recomend thanks

you opened up the thermostat housing and there was no thermostat?

does the cluster read a temp?

have you tried bleeding the coolant system? i would start there

 

Have you tried a new radiator cap??

 

Ya no thermo I put a new cap on it it's a oem one on a aluminum rad

 

And the guage doesn't go up

 

And after the new cap it still does this?

 

Ya

 

well put a thermostat n, replace cap, bleed system and if ur still having probs check head, replace hg. Is there oil in ur coolant? vice versa? if so head gasket or r u losing coolant and cant find where its leakin than its the hg.

 

No oil In coolant and no coolnt in oil but I think it is losing coolnt not sure wer but should I tryn bleed it and throw thermo in

 

If I do the h gasket I gotta resurface the head as well right or can I jus slap
the gasket on

 

if the headgasket is the issue you must resurface the head or the issue will re occur

 

No you need to check for bad valves/valve seals and resurface.

 

water boils at 212*F. Engines operate around the 200* mark.

Get a proper coolant mix and rewire your turbo timer to include your cooling fan circuit.

 

check the head for straightness to see if it requires machining

and definitely refill with coolant, not water.

 

Ok so I drained all the water out and filled with coolnt an bled the whole thing squeezed the hose and coolnt came from the cap so I changed to another. Pulled it outta the garage and the exhaust had a lil white smoke comin out was still cold then reved a lil and it stoped took it for a decent drive and by time I got home there was smoke coming from the cap and can see it squirted a lil coolnt out as well but no boiling in the resivor wat you guys think now

u need a thermostate in there period. U may b able to throw a hg on it if thats the problem but u should get the head checked and milled if the machine shop says its necessary.

 

Do u think forsure it's the hg or poss the rad cap

 

Ttt

 

Try another cap.

 

Ya I think the top of the rad wer the cap goes on is kinda messed up so poss need another rad hopen the white smoke was jus all the crap burnen off from only haven water in there and the car was still lil cold

 

Yeah I was gona say if another cap doesnt work then theres something wrong where the cap goes on the radiator
