Me too but probably since the late 80s… used to be a Sunday morning ritual, brushing gunk into a slightly warm engine…. Lovely smell !

Unfortunately Gunk lost all its power some time back when it changed to a water based product :~
Little use on heavily contaminated parts- Screwfix sells a degreaser under their own brand "No Nonsense" 5Ltr and was/is a good price for another water based product but equal to Gunk & cheaper? (Both are suitable for mild cleaning though) On a modern car with all those electrical connectors & associated parts then care must be taken with water particularly pressure washing. Shine on! Bob. |

This is my opinion, others will not agree, I respect that, but....
On Volvo's there is no danger from carefully power washing the engine bay. All electrical connectors are well sealed, all modules/ECU's are well covered. Coil packs are sealed and well out of the way. On Volvos, all of the analogue engine sensors (i.e. not those that are simply on/off) are bridge type in that they have a 5v feed, ground and signal - there is a reference resistor within the sensor so even if the connector is contaminated, it doesn't sway the signal. Even the alternator is okay to get wet (although I wouldn't spray it driectly so as not to damage the insulation on the windings), it's 12v so water isn't going to cause a short and all of the voltage regulator etc. is potted and water proof. What kills alternators is oil and fuel contamination. Hence I'd rather wash an engine off with a pressure washer and cold water than use any solvents, alkaline soaps or detergents. I have a cheap entry level £100 Karcher power washer which is relatively low power that I use for that purpose, only ever had one very temporary issue on wife's VW when I really went to town on it. Next time I clean one of my engines I will post a vid...

Getting decent fluid for parts washers is hard now as well.

Be aware if pressure washing a C70 Mk2 engine bay, in particular with regard to getting any water in the air filter box.
There is a cooling duct which runs from inside the airbox down to the ECU located in the front nearside wheelarch (RHD). I discovered this when inspecting the ECU in my car whereupon I further discovered the signs of water ingress/corrosion on the ECU casing. Last edited by Lancee; May 5th, 2024 at 16:29. |

Lots of conflicting opinions. I’ve ordered a 5l drum of G101 and will give it a combination of spray/agitate/jetwash and post the results. I’ll try some silicone spray in the plastics too.
