Subaru Head Gasket
Subaru Head Gasket
Those of us that live in Western MA were pretty lucky this year when it comes to cold weather (if you don’t like snow or cold that is). We only had a few weeks of really cold weather, but other than that the temperatures have stayed pretty warm. A long time customer had come in a few weeks back concerned about a loss of heat in his Subaru. When he would warm the car up in the morning the temperature coming out of the vents would stay icy cold no matter how long he ran the car. Sometimes the fix can be something simple such as a loose clamp or a faulty thermostat. Unfortunately for this customer he needed a Subaru Head Gasket Replacement
Subaru Coolant Leak
It’s very common in the winter to see cars coming in with heat loss and in the summer we see cars come in overheating. Both concerns are typically (but not always) caused by the same issue, a Coolant Leak. For this Subaru Repair we road tested the car to verify what was happening. When we pulled the car into the shop we found that there was a significant loss of coolant. This will most definitely cause the customer’s concern.
We then applied some pressure to the cooling system to help us identify where the coolant is leaking and hoist the vehicle on a lift to check for any obvious leaks. Coolant was actually leaking out of the driver side Subaru Head Gasket. When inspecting the passenger side of the engine there was a large amount of coolant staining that indicted there was a small leak from that side of the engine. If left untreated this small leak will most definitely turn into a larger leak. It was determined that both cylinder heads would need to come off this engine to be checked for warpage or cracks.

This is one of the cylinder heads after being cleaned up and serviced at the machine shop
We removed both Subaru Cylinder Heads and had one of our Certified Technicians look them over. There were no obvious issues but to be safe we sent them to a machine shop to have them properly cleaned and serviced. The machine shop makes the mounting surface perfectly smooth so that the gasket can seal properly. Then they clean all of the valves and replace any seals in the cylinder heads. The heads always come back a day or so later looking and functioning like brand new Subaru Cylinder Heads.
Subaru Head Gasket Replacement Tip
A few months back we put a picture of another Subaru Head Gasket Replacement on our social media. There were some question as to how we were doing the job. For those that don’t know, most shops that do this job once or
The trick is using some special tools that we have had specially fabricated to make this job go much smoother. You can also achieve the same result without the special tools by using carefully positioned wedges of wood that will give you the proper angles to remove the heads while keeping the intake out of the way. Doing this puts no stress or strain on anything in the engine compartment and allows plenty of room to remove and reinstall the cylinder heads. There really is no need whatsoever to remove the entire engine. It’s just a wasted expense that the customer really doesn’t need to incur.
Now it’s time for the whole job to go back together. Because of the mileage on the vehicle we installed a new timing belt and water pump too. The vehicle was roughly 10,000 miles away based on the service history but the customer decided to replace them while the engine was going back together instead of reinstalling the old ones, then have to take it all back apart again in a few months when he hits the required mileage. It saved him quite a bit of money doing it this way. After all parts were installed we performed all the necessary scheduled maintenance so that this customer can just enjoy their car for a while and not have to worry about anything.
It’s important that when cleaning the block to make sure none of the metal shavings get into the cylinders, oil passages, or coolant passages. We plug them all with shop towels while prepping them
We see a lot of Subaru Repairs that require the replacement of the Head Gaskets. Unfortunately it’s a very common issue on these cars. But the repair process is pretty quick and the price is reasonable. We then back the repair with our 2 year, 24,000 mile Nationwide warranty and Free 12 month roadside assistance.
