Oil in coolant tank of my Chevrolet Cruze; Need a solution

This is most likely due to the oil cooler gasket leak, but I have gone to 3 different garages including the erstwhile authorized Chevrolet A.S.S ,and each one has a different diagnosis ranging from head gasket to oil cooler.

BHPian Cruzecontrol recently shared this with other enthusiasts.

Hi,

This being a first post, please excuse if the placement of this query in this forum is incorrect. I have a Chevrolet Cruze LTZ 2012 model with an odo of 1,35000 kms, and running fine except for oil in the coolant bottle. This is most likely due to the oil cooler gasket leak, but I have gone to 3 different garages including the erstwhile authorized Chevrolet A.S.S ,and each one has a different diagnosis ranging from head gasket to oil cooler. Can anyone recommend a trusted and knowledgeable FNG in Gurgaon for this job? Thanks in anticipation.

Regards,

Here's what BHPian Indian2003 had to say on the matter:

You have only 2 possibilities. The head gasket or the oil cooler/heat exchanger. It is not up to you to tell them what to do. They should diagnose the fault and fix it. I would try to find another shop which has the gear to test the head gasket.

A pressure gauge will easily indicate a leaking head gasket. This is the first thing that is done for a suspected leaking gasket.

Take it to someone who knows what they are doing.

As an amateur mechanic, I would lean on the head gasket as a leaking oil cooler normally sends coolant to the engine oil and not oil to the coolant.

If you diagnose the fault for them they will blame you for the wrongs they do.

Here's what BHPian Shreyans_Jain had to say on that matter:

Did the car overheat? In that case, it is the head gasket that has gone. You can contact Anupam Shukla of Worlds of Service, Noida. The number is there in a dedicated Worlds of Service thread, and also in the FNG thread.

Please note that the engine has undergone damage, and will in all probability never be the same again. If not performance, then in terms of reliability or emission compliance. Your best course of action will be to sell the car off at the earliest. As a 2012 model, it is anyway nearing the 10 year limit for diesel cars in NCR.

Here's what BHPian Kedrock had to say on the matter:

Hi,

Please check if there are any traces of coolant in oil sump (pull the dip stick out and inspect). If not, replace the oil cooler along with gasket and flush the cooling system. If yes, the engine might have overheated and will need to be dismantled and undergo further inspection.

I would recommend to get the above work done at an authorized Chevy service station only. You will get warranty if the issue crops up again within a year or 20000 km (whichever is earlier).
