Hi guys. Long time no post. Hopefully you guys are good and healthy and all that good stuff.
Anyways, kinda need some help. Kinda long story. Hiks.
TL;DR - Car is overheating for the, idk, bazillionth time. Top overhaul?
My car has been overheating a few times since I did the engine transplant (JB-JL, around feb 2014).
Last year, about 4 months after the transplant, the hose (betul ke?), the small L shaped hose thing under the intercooler cracked, and the water in the radiator leaked. After changing all that, all was well again.
Then, somehow a few months after that, temp increased again. No leak this time. Decided to flush radiator, and sent for service to specialist. Pretty much cleaned the inside and the radiator sampai berkilat. And all was well again.
Then about last week, after reaching home from berjimba, as soon as I got out of the car, heard rumbling noises from engine bay. Temperature didnt increase this time. Thought it was the aircond belt, because that thing has been making that similar sound sometimes. Didnt care to check.
Then last night, went to KL and back (live in shah alam), about 2km from home, temp raised again. Stopped, and heard the same noise as last week. Apparently the water in the spare tank was boiling like crazy. Waited till cool, went home.
This morning, checked, all the water was gone. Refilled, let the engine run for awhile (15mins+-) then fan kicked in. So i guess fan is working. Kot.
Im not sure whether this time its the:
-waterpump or
-radiator cap or
-leak again or
-radiator fan.
Conclusion: Is a top overhaul in order? If so, where can I go to do this so I dont get conned? Im a noob.

I have had to stop at the side of the road too many times now, and honestly Im tired of it. Ive been driving slow after flushing the radiator until now simply because I was kinda traumatized by it. Im scared of overheating again. And last night memang betul betul jadi lagi. Very stressful. Im driving a turbo charged car, yet i drive slower than an N/A. This sucks. Please help.
Thanks guys
