EMPI Super Kooler Oil Cooler | Doghouse | VW Type 1/2/3 1971–1979 | Cerakote (98-1189-B)

EMPI Super Kooler Oil Cooler — Doghouse | Cerakote (98-1189-B)

This is the doghouse cooler — 1971 and later. Open your engine lid: if there's a rectangular oil cooler box hanging off the outside of the fan shroud on the driver's side, you have a doghouse and this is your cooler. If the cooler stands upright inside the shroud, you have an early upright engine and you want the upright Super Kooler, 98-1186-B instead. Can't tell? Send us a photo of your engine bay and we'll tell you — we look at these all day.

The EMPI Super Kooler isn't a plain replacement, it's a hardware upgrade. EMPI had CSF Radiators build it — a company that makes radiators for a living — specifically for doghouse fan shroud engines.

Vehicle Fitment

Fits Type 1 engines with doghouse cooling, stock 1600cc through high-displacement performance builds:

• VW Beetle & Super Beetle: 1971–1979
• VW Bus (Type 2): 1971–1979, Type 1 / doghouse engine only
• VW Karmann Ghia: 1971–1974
• VW Thing (Type 181): 1973–1974
• VW Type 3: 1971–1973, doghouse-equipped engines
• Dune buggy / sand rail: any doghouse Type 1 build

Doghouse fan shrouds only. It will not seal on an upright (pre-1971) shroud.

Key Performance Features

• Bar-and-plate core: EMPI puts it at 10% more cooling volume than the OE tube-and-fin in the same footprint.
• Cerakote ceramic coating: an ultra-thin thermal barrier that sheds heat faster than paint or raw aluminum.
• Pressure tested to 120 psi (8.3 bar) — it will take a high-volume oil pump without fatigue.
• Billet CNC top, cast bottom for structural integrity.
• Built-in M10x1.0 sensor bung: put a real oil temp or pressure sender in the cooler instead of guessing off a dipstick gauge.
• Comes complete: the "Hoover bit" air tin and premium Elring seals are in the box, so you're not hunting parts halfway through the job.

EMPI's Tested Numbers

These are EMPI's published test figures, not ours:

• 47% colder at the cooler outlet than the OE unit in equivalent conditions
• 5% better than the larger Type 4 oil cooler
• 86% colder at the outlet when paired with the EMPI Super Shroud

Worth saying plainly: that's the temperature of the oil leaving the cooler, not the temperature in your sump. Your sump temp still depends on your tin, your timing, your jetting and how hard you drive it. But the direction is right and the construction is honest.

Fit the Hoover Bit

The "Hoover bit" is the small piece of tin that seals the gap between the cooler and the shroud. Its whole job is to stop air taking the easy path around the cooler. Leave it out and the fan pushes air past the cooler instead of through it — you'll have bolted on an expensive part that does almost nothing. It's included here. Fit it.

Frequently Asked Questions

• How do I know if I have a doghouse shroud? Open your engine lid. A rectangular oil cooler box on the outside of the shroud, driver's side, means doghouse — 1971 and later. A cooler standing up inside the shroud means upright — 1970 and earlier.
• Will it fit a stock 1600cc engine? Yes — any doghouse-shroud Type 1 engine from stock 1600cc up through high-displacement builds.
• Do I need a high-volume oil pump? Not required, but one pairs well on built engines (1776cc+).
• Will my stock tin still fit? Yes — the included Hoover bit replaces the stock cooler tin and fits the standard doghouse shroud.
• What sensor fits the M10 bung? Standard M10 x 1.0 temperature or pressure senders — AutoMeter, VDO and most aftermarket gauge senders are this thread.
• Is the Cerakote durable? Yes — it's the ceramic finish used on firearms and engine components. It won't chip, fade or burn off like paint.
• Should I do the shroud at the same time? The 86% figure is the cooler and shroud working as a pair, so if you're in there it's worth pricing both. See the Oil & Cooling collection.
