we installed misimoto radiator and rad cap and after market fans

 

still overheating when driving long periods ( 45mins) and i smell alot of burnt oil. i dont over heat in traffic

 

 

the radiator hose both top and bottom are not clogged and there is no air lock in the system

 

there is a crackling noise under the turbos an a lot of steam at the rear of the engine.

 

i thinking either

 

waterpump

 

thermostat (after i remove do i have to replace since i like in the caribbean)

 

or even head gasket ( not seeing an bubbles when the car idling so doubt it)

 

i used proper weighted amsoil oil and i dont have an oil cooler

 

only running 15 psi right now which is stock

 

 

 

.. on the brighter side i beat ths fuk out of a ninja this morning.. and yes he was trying to race me,,, i crushed him... felt great(best birthday gift ever).. cant wait to get this problem solved and run my single turbo setup:)

 

 

 

Any positive suggestions would be widely appreciated :0

So you're car is not right and you are racing motorbikes in it. Prime example why ownership should be limited to people who actually care about cars.

 

 

Amen to that Dave :)

 

on another note Ravi i am sure the more clued up members will be along in a min to help u out :)

If you are getting a lot of steam on the rear of engine, then the first thing to check is the heater hose that goes on top of the cylinder head at the rear, they do go hard and brittle over time.

 

Good call.

 

If you have steam then you have a leak somewhere.

yeah but with that problem, it would only overheat when the water runs low.. top it back up and it would be okay untill it leaked out..

 

not sure what your on about, any water leak on a car engine will eventually cause overheating, obviously if you top it up it wont overheat until the leak gets bad enough

 

The op says he's not losing water yet has steam at the back of the engine, i dont see how that is possible as the only way you get steam is from having a water leak.

 

Better info is required from the op to help sort his problem in my opinion
