What do customers ask about Cooling System Repair?

Common questions and tips from our work with Commerce customers.

What coolant should go in my diesel truck?

It depends on what the engine was built to run. Older diesels often take conventional green coolant, while most modern diesels use an extended-life OAT or HOAT formula, and mixing the two can gel additives and shorten water pump life. We check what is in the system now, match the correct formula and 50/50 water mix, and label the result so the next service stays consistent.

How long does a cooling system repair take?

Most cooling repairs on a diesel pickup are finished in a few hours to one day, depending on the part. A thermostat or hose swap is quick once the system is drained. A radiator or water pump replacement takes longer because of access work around the front of the engine. We confirm the actual scope after pressure testing, before any wrench turns.

Should I top off coolant and keep driving?

For a short hop to the shop, topping off can get you there, but watch the gauge closely. Diesel cooling systems pressurize to roughly 15 to 16 PSI when hot, and a leak usually worsens under that pressure. If coolant disappears fast, the temp climbs, or you smell sweetness in the cab, stop driving. Continued heat on a diesel risks head gasket damage.

Can I find a coolant leak myself?

You can check visible items: hose clamps, the reservoir level, wet spots under the truck after it sits overnight, and a worn belt. Cold checks are safe. Opening the radiator cap hot is not, since pressurized coolant can scald. Anything deeper, like a head gasket or heater core, needs a pressure test and block test that a shop can run.

Tip

Catch small coolant loss early

Check the reservoir every couple of fill-ups, especially before towing through Georgia summer heat. A level that drops an inch over weeks points to a seep a pressure test will find quickly. A level that drops in a day means park it. Catching seeps early is the whole difference between a hose clamp and a head job.
