The 6.4 Powerstroke cracks its radiator, its exhaust up-pipes, and then its EGR cooler — usually in that order. We replace all of it in one visit, at your home.
The 6.4 Powerstroke's factory radiator has a known weak point: the core cracks along the seams from the constant expansion and contraction of heavy towing cycles. You'll find a pink puddle under the front of the truck after a hard run — sometimes only when it's fully hot, which is why it can be maddening to catch.
At the same time, the up-pipes — the exhaust pipes feeding the twin turbos — crack at their expansion joints. That's the metallic tick you hear under load, and it's not just noise: leaking exhaust before the turbos means lost drive pressure, lazy spool, and soot blowing where it shouldn't be.
Here's how they connect: once the radiator leak drops your coolant level, the EGR cooler is the first thing to run dry. An EGR cooler running low on coolant overheats and fails internally — and now you're losing coolant with no external leak at all, because it's going out the exhaust. Fixing the radiator without checking the EGR cooler, or vice versa, is how owners end up paying for this job twice. We do all three together.
If your Ford is doing any of these, this is the likely cause:
A cracked radiator on a 6.4 isn't a stable leak — the crack grows with every heat cycle, and the day it lets go properly you're overheating on the 401 with a trailer behind you. The bigger cost is what low coolant does next: it kills the EGR cooler, and a failed EGR cooler pushes coolant through the engine. Cracked up-pipes, meanwhile, are slowly washing hot exhaust over everything near them. None of these get cheaper by waiting; they recruit other parts.
Yes. Radiator, up-pipes, and EGR cooler are all in-truck repairs — no lift required, no cab removal. We do it in one full day at your home with a level parking spot. We bring the coolant, the tools, and take the mess away.
Because it isn't just a radiator job — the up-pipes are buried and slow to access, and dealers bill every hour of that at their door rate plus list-price parts. We give you one flat price for the complete package — radiator, up-pipes, EGR cooler, coolant — agreed before we start. No running meter, no mid-job surprises.
It may not be — that's the EGR cooler signature. When coolant disappears with no external leak, it's usually going out the exhaust through a failed cooler core. That's exactly why we test the whole system instead of just swapping the radiator and hoping.
Cracked up-pipe expansion joints. The crack opens when the exhaust gets hot and pressurized — load and towing — and quiets down at idle. It costs you boost and turbo response, and the escaping exhaust heat cooks nearby components, so it's worth fixing alongside the cooling work while everything is apart.
