Hello and welcome. My name is ***** ***** you for visiting the site. *** A BAD RATING HAS NOTHING TO DO WITH ANY DEPOSIT YOU MADE *****

.

Let me just say that any money that you paid, or if you have a subscription, that money stays in your account until the answers are rated, (positive) regardless of how fast or how long it may take to get finished. You can FOLLOW UP AT ANYTIME, even after rating.

.

Not that a bad head gasket will cause those codes to set. However, to be sure it does need a head gasket.

.

The first thing that you want to do is check the cooling system for any exhaust gases. Make sure that it’s full first. There is a tester for that, that you can get from Autozone for about $20. They will normally lend you the tester and you just buy the fluid for about $8. It comes with instructions, but there is a blue fluid that is used in it, if the fluid turns yellow, that is exhaust gases.

.

Block tester available is:

Napa BK.(###) ###-####/p>

OEM/Block Tester AUTOZONE

Part Number:
27145

http://www.autozone.com/autozone/accessories/Tools/Block-Tester/_/N-25dh?filterByKeyWord=block+tester&fromString=search

.

*****You will want to check it at different RPM’s and at different temperatures***

..

.

If there are any exhaust gases in the cooling system, that will cause more pressure than desired and will allow the engine to burn coolant and/or heat the coolant up too high. Most times not filling the crankcase with coolant either and not smoke out the exhaust.

If there are, then there would be an internal engine problem, like a head gasket or head.

.

Please don’t forget to rate the answer, **** THAT IS THE ONLY WAY I GET PAID **** if you need any more on it, I will be here.
